When you open a bank account, you receive a unique identifier known as a bank account number. This number is crucial for ensuring financial transactions like deposits, withdrawals, or transfers are routed to the correct account within the banking system. This article will dig into what your bank account number represents, how it's structured, and its importance in your financial activities.
What Is a Bank Account Number?
A bank account number is a unique sequence of digits assigned to an account holder by a financial institution. It works much like a physical address for your account within the broader network of financial institutions, distinguishing your account from others and ensuring transactions are recorded accurately.
Structure of a Bank Account Number
The structure of a bank account number varies by financial institution and country, but generally includes several key components:
Importance of Your Bank Account Number
Managing Your Bank Account Number
While a bank account number is a powerful tool for managing financial transactions, it also requires careful handling:
Your bank account number is more than just a sequence of digits — it's a crucial part of your financial identity, essential for directing and protecting the flow of your money. By understanding how your account number works and implementing robust security measures, you can secure your financial health and keep your funds safe. Whether you're receiving a paper check, setting up a direct deposit, or making online transactions, the integrity of your bank account number is paramount.
Things to Know: Bank Account Number vs. Routing Number
Bank account numbers and routing numbers are both critical components of the banking system, but they serve different purposes and have distinct characteristics. Understanding the difference between these two numbers is important for handling financial transactions effectively. Here's how they differ:
A bank account number uniquely identifies an individual's personal account within a bank. It specifies where funds should be deposited or withdrawn.
A routing number (also known as a sort code in some countries) identifies the bank itself, and sometimes the branch where the account is held. It's used to route money transfers like direct deposits and bill payments to the correct bank.
Additionally, the geographic validity of these numbers varies. A bank account number is valid across the entire bank and doesn't change even if the account holder moves to another branch, unless the banking system specifies otherwise. A routing number, on the other hand, is often specific to a region or branch, particularly in larger banking systems like those in the United States. This specificity helps manage and route payments accurately within the complex network of branches and banks.
When setting up processes like automatic bill payments or direct deposits, both numbers are generally required. The routing number first guides the payment to the correct bank or branch, ensuring the institution is properly identified. The bank account number is then used to route the funds to the individual's specific account. Together, these numbers work to streamline financial transactions, making them secure and efficient across the banking network.

Conclusion
In conclusion, understanding the purpose of your bank account number is crucial. This also comes with understanding its distinction from a routing number to effectively manage your finances and ensure the security and accuracy of your transactions. A bank account number serves as a unique identifier for your specific account within a financial institution, playing a vital role in correctly directing funds, whether for deposits, withdrawals, or automatic bill payments. A routing number, on the other hand, identifies the financial institution and sometimes the specific branch, essential for routing transactions to the correct bank.
The geographic validity of these numbers — where the bank account number stays constant across branches while the routing number can vary by region or branch — highlights the complexity and structured approach banks use to manage and route payments. Both numbers are indispensable in modern banking, from setting up direct deposits to processing paper checks and making secure online transactions.
By maintaining a solid understanding of how these numbers work and applying rigorous security measures, like keeping your information confidential and monitoring account activity, you can protect your financial health and ensure your banking interactions are both smooth and secure. This knowledge not only empowers you to manage your accounts more effectively, but also protects you from potential fraud and errors in an increasingly digital world.

Immigration

The ITIN is obtained through IRS Form W-7 along with identity and foreign status documentation. A passport is the only document that satisfies both requirements on its own. The process takes between 7 and 11 weeks.
The ITIN allows you to file tax returns with the IRS, including claiming credits such as the Child Tax Credit and the Earned Income Tax Credit.
Some banks and credit unions accept an ITIN as an alternative ID to an SSN for opening accounts. Platforms like Común do not require either an SSN or an ITIN.
For entrepreneurs, the ITIN is vital for filing business taxes and applying for an Employer Identification Number (EIN).
Consistently filing taxes with an ITIN can demonstrate good moral character, a factor considered in some immigration cases.
In the absence of an SSN, the ITIN is recognized by financial institutions and government agencies as a valid identification number.
In some states, the ITIN allows access to a driver’s license, health insurance, or in-state college tuition rates.
Using the ITIN consistently links your tax data to your identification number, reducing the risk that someone files a return in your name.
The ITIN allows you to file tax returns with the IRS, claim tax credits such as the Child Tax Credit, open bank accounts at institutions that accept it, and in some states access services such as driver’s licenses or in-state tuition. It is the tax identification number for those who do not qualify for an SSN.
No. The ITIN is exclusively for tax purposes. It does not authorize you to work legally in the U.S., does not generate Social Security credits, does not provide automatic access to federal benefits such as Medicare or unemployment, and is not equivalent to an SSN for most government procedures. It is a tool for tax inclusion, not immigration status.
In general, filing taxes with an ITIN can be beneficial in immigration processes because it demonstrates a history of tax compliance and “good moral character,” one of the criteria evaluated in some adjustment-of-status cases. However, the impact varies by case — consult an immigration attorney before using it as an immigration strategy.
Some banks do accept an ITIN. Bank of America and certain local banks have specific programs for ITIN holders. However, many large banks require an SSN. Alternatives like Común do not require either an SSN or an ITIN — they accept a passport, consular ID, or other Latin American IDs for immediate account opening.
Yes, partially. Some credit card issuers and lenders accept an ITIN. Certain mortgage programs (ITIN loans) allow you to buy a home without an SSN. Building credit history with an ITIN is possible, although more limited than with an SSN. Credit built with an ITIN generally does not automatically transfer if you later obtain an SSN.
You submit IRS Form W-7 along with identity and foreign-status documentation — a passport is the only document that satisfies both requirements on its own. You can mail it with your tax return, go in person to an IRS Taxpayer Assistance Center, or apply through an authorized Certifying Acceptance Agent (CAA), which is the fastest and safest method.

Checking account
8 min de lectura
Checking accounts are an essential tool for managing your personal finances, and the main type of account you'll use day-to-day in the United States. In this article, we'll walk you through everything you need to know about them and how to choose the best option for you.
What Is a Checking Account and Why Do You Need One?
A checking account is a type of bank account that lets you deposit and withdraw money easily. It's the account most commonly used for everyday transactions like paying bills, making purchases, and receiving your paycheck. You need one because it gives you a safe place to keep your money and lets you handle financial transactions efficiently.
Advantages of Having a Checking Account
Checking accounts offer several advantages:
Differences Between Checking Accounts and Savings Accounts
While a checking account is designed for everyday transactions, a savings account is designed for storing money long-term. Savings accounts usually offer higher interest rates, letting you earn money on your savings. However, they aren't as accessible as checking accounts and may have restrictions on how many transactions you can make.
Common Requirements to Open a Checking Account
Required Documentation
To open a checking account, you'll generally need to provide a photo ID, proof of address, and your Social Security number or tax ID number.
At Común, online banking for immigrants in the United States, the main documents you'll need are:
Opening a checking account with Común is 100% online and can be done in under 5 minutes.
Minimum Deposit and Other Conditions
Some banks require a minimum deposit to open a checking account. They may also charge fees if your balance drops below a certain level. For example, Chase Bank offers the Chase Total Checking account, and Citi Bank offers the Citi Basic Banking Package, both of which include access to thousands of ATMs and online and mobile banking service. However, like many other traditional banks, they charge a monthly service fee of around $8 to $12 unless you meet certain average monthly balance requirements or a minimum amount deposited through monthly direct deposits. On top of that, they may charge overdraft fees of $39 or more.
With Común, however, there's no minimum deposit amount, no minimum monthly balance, and no monthly service fee — and no hidden costs in the fine print.
What They Don't Tell You About Checking Accounts in the United States
You can generally access the funds in your account through ATM withdrawals, checks, electronic transfers, and debit cards. It's important to know, though, that each bank may charge fees for each of these operations, so it's worth knowing them before opening an account so you can compare your options and find what's most practical for you.
Many banks also require an initial deposit to open a checking account. The amount varies by bank, but can range from $25 to $100. Común's checking account has no such cost — the initial deposit required to open one is $0.
Checking accounts can also come with fees beyond the monthly maintenance fee, like ATM fees, overdraft fees, and more. Some banks waive the monthly fee if you maintain a minimum balance or have regular direct deposit. With Común, you can deposit and withdraw cash at no cost at more than 55,000 ATMs across the United States, found at places like Walgreens, CVS, Target, and more.
Some banks offer overdraft protection that keeps checks from bouncing or your debit card from being declined if you don't have enough money in your account. This service can come with high fees, though, so it's important to understand the terms.
And if you're living in the 21st century, access to online and mobile banking lets you check your balance, pay bills, deposit checks, and transfer money from anywhere.
One special feature of checking accounts is FDIC insurance. Banks in the U.S. are typically insured by the Federal Deposit Insurance Corporation (FDIC). This means that even if the bank fails, your money — up to $250,000 — is protected. Común's accounts, for example, are FDIC-insured up to $250,000 through partner bank Community Federal Savings Bank (CFSB).
Checking accounts are an essential tool for managing your personal finances. They give you a safe place to keep your money and let you handle financial transactions efficiently. When choosing a checking account, you should consider factors like fees, services offered, the bank's location and reputation, and interest rates. With the right information, you can choose the checking account that best fits your needs.
If you're looking to open a checking account and get a debit card, what are you waiting for? Do it with Común.

Opening an online banking account is very easy these days. We’ll show you the key factors you should consider when choosing the digital bank that best fits your profile, since there are multiple options on the market. We’ll also explain how to open an online account effectively.
Opening an online banking account in the U.S. can be done in minutes from your cell phone. All you need is a valid ID, a U.S. phone number, and your address. Platforms like Común do not require an SSN and accept more than 100 Latin American IDs, making the process accessible for immigrants from day one.
Online banking consists of managing your money and carrying out financial transactions through the internet or a mobile app, without needing to visit a physical bank branch. This includes checking your balance, making transfers, paying bills, depositing checks, and more.
The main advantages are 24/7 availability, access from anywhere, no lines or office hours, and generally lower fees than traditional banks because they do not have physical infrastructure costs.
Not all online banks are the same, especially for immigrants. The most important factors to consider are:
The general process for opening an online banking account in the U.S. is as follows:
Many traditional banks require an SSN to open an account. However, Común allows you to open an account with a passport, consular ID, or other forms of Latin American identification. There is no minimum balance, no monthly fee, and the process is completely in Spanish. The account includes a VISA debit card, access to Zelle, early direct deposit, and remittances starting at $2.99.
Yes. Digital banks like Común let you open an account 100% online from your phone, without visiting any branch. All you need is your ID and a U.S. phone number. The process takes about 3 minutes, and approval is instant in most cases.
It depends on the bank. Traditional banks generally ask for an SSN or ITIN, photo ID, and proof of address. Común accepts more than 100 Latin American IDs — passport, consular ID, national ID — without needing an SSN or minimum balance. You only need a U.S. phone number and your current official identification.
Yes, if they are backed by the FDIC. Regulated digital banks in the U.S. offer the same level of protection as traditional banks: up to $250,000 per account holder insured federally. They also use SSL encryption, two-factor authentication, and anti-fraud systems. Común operates through Community Federal Savings Bank, an FDIC member.
Yes, there is no legal limit. Many people have accounts at multiple banks: for example, one for everyday spending and another for savings. You can have a Común account for day-to-day use in the U.S. and keep your account in your home country to receive funds when you travel.
Most digital banks approve the account within minutes. The physical card arrives by mail in 5-10 business days. However, the virtual card is available as soon as you are approved, allowing you to make online purchases or add the card to Apple Pay or Google Pay right away.
Yes. All online banking accounts that have a routing number and account number accept payroll direct deposit. Común has its own routing number and lets you generate a pre-filled form to give to your employer. Many digital accounts also advance the deposit up to 2 days before the official date.

Financial Education

If you’re new to the United States or facing financial challenges, it’s very important to have strategies to prepare for any eventuality.
An emergency fund is an excellent way to do this, and it also builds your financial literacy. It’s a cash reserve meant to cover unexpected expenses such as illness, job loss, home repairs, etc.
Having this cushion gives you peace of mind and removes uncertainty about the future, since it provides the liquidity you need to handle the unexpected.
You might think you need to earn a lot to build an emergency fund. Below, we’ll show that even with limited resources, you can start securing a future without financial complications.
Surely at some point during your time in the U.S., you’ve faced financial emergencies that made it hard to cover daily expenses—traffic fines, immigration procedures, illnesses, unemployment, repairs, etc.
An emergency fund is meant to support your finances precisely when those events occur. It’s savings set aside to handle all kinds of unforeseen expenses.
Beyond a stash of money, think of the emergency fund as a way to maintain peace of mind and reduce stress; it helps you preserve financial stability and avoid going into debt.
Knowing how to size an emergency fund is the first dilemma for many who aren’t used to long-term saving. While the ideal target is 3–6 months of basic expenses, if your income is limited you can start with small savings goals.
Below is a comparison of how your emergency fund would grow assuming expenses equal to 50% of total monthly income.
Monthly income
Approx. monthly expenses
3-month savings target
6-month savings target
$1,500
$750
$2,250
$4,500
$2,500
$1,250
$3,750
$7,500
$3,500
$1,750
$5,250
$10,500
It’s very important to choose a safe, easy-access place for your emergency fund and keep it separate from the money you use for daily expenses.
Today there’s a wide variety of savings accounts, both from traditional financial institutions and online platforms.
Whatever you choose, the following options are not recommended for storing your emergency fund.
Whether under the mattress or in a piggy bank, keeping your emergency fund in cash is not a good idea for several reasons. First, there’s the risk of theft or loss. Also, the cash earns no interest and loses value to inflation. Another drawback is low accessibility if you need to cover expenses digitally.
While it’s true that opening a checking account can be challenging for immigrants in the U.S., there are accessible options so you don’t have to keep the emergency fund in cash.
Although investments have advantages, high-risk ones involve sharp fluctuations that could cause losses. They also often require locking funds for a long period.
If you’re new to personal finance, the first thing to know is that an emergency fund isn’t just for high earners. The key is to examine your lifestyle and spend according to a savings plan.
The first step is to list all your fixed monthly expenses and the amount for each.
Example:
Then list your variable expenses and calculate a budget. To be more accurate, track all your spending by category.
Example:
Finally, total your monthly spending. In the example above, monthly expenses add up to $2,100.
At first, reaching 3–6 months of expenses can sound impossible. You don’t have to give up what you enjoy—start with a small amount each month and increase gradually.
Your first savings target depends on your income, your expenses, and the resulting capacity to save.
After doing the math, add “savings” as a fixed expense so you set that money aside every month.
Ideally, open a new account so your emergency fund doesn’t mix with daily-use money.
An easy way to fund it is with automatic transfers so you don’t have to remember to move money each time.
After a few months of hitting a small goal, reassess your budget and consider increasing your savings as you’re able.
As you can see, an emergency fund provides financial security for unexpected events. It’s also easy to start with small goals and increase gradually until you reach financial peace of mind.
The next step is choosing a safe place to keep your emergency fund secure.

Your emergency fund is intended to cover unexpected events like medical bills, appliance breakdowns, layoffs, etc. When that happens, use it—and keep saving afterward.

Getting married is a major milestone. When one spouse is a U.S. citizen and the other lives abroad, the immigration process can feel overwhelming, especially when you start seeing terms like IR1 visa, CR1 visa, Form I-130, NVC, and consular interview.
Whether your spouse is waiting in Mexico, Colombia, or another country in Latin America, understanding the process can help you reduce stress and prepare for each stage.
This guide explains the IR1 visa and CR1 visa process in plain language, including timelines, costs, required documents, and what to expect during the consular interview.
The guide is for informational purposes only and does not constitute legal advice.
The IR1 and CR1 visas are both immigrant visas available to spouses of U.S. citizens, allowing them to enter the United States as lawful permanent residents. The key difference between them lies in the length of the marriage at the time of visa issuance. In both cases, permanent resident status begins upon entry into the U.S., and the physical green card is mailed to the holder shortly after arrival.
Generally, you may qualify if:
Unlike fiancé visas, the IR1 / CR1 are designed for couples who are already legally married.
For many immigrant families, the process begins while one spouse remains in countries such as Mexico or Colombia and waits for consular processing at locations like Ciudad Juárez, Mexico City, or Bogotá.
Although the IR1 and CR1 visas follow the same application process, they lead to different types of green cards. The key distinction is whether the marriage is less than two years old or at least two years old when the green card is issued.
| Feature | CR1 visa | IR1 visa |
|---|---|---|
| Marriage length | Less than 2 years | 2 years or longer |
| Green card type | Conditional permanent residence | Permanent residence |
| Green card validity | 2 years | 10 years |
| Additional filing required | Must later remove conditions | No removal of conditions required |
| Eligibility basis | Married to U.S. citizen | Married to U.S. citizen |
If the marriage is less than two years old when permanent residence is granted, the spouse typically receives conditional residence through a CR1 visa. Couples later file to remove those conditions. If the marriage is at least two years old, the spouse generally receives an IR1 visa and a standard permanent resident card.
Before starting an application, it's important to understand which visa category matches your circumstances. IR1, CR1, K-1, and K-3 visas were created for different stages of a relationship.
These visas are intended for couples who are already married. After approval and entry into the United States, the spouse becomes a permanent resident.
The K-1 visa is for couples who are not married yet. The foreign fiancé enters the United States, the couple marries, and then applies for adjustment of status.
Although the K-3 category still exists in immigration law, it is rarely used in practice today. Most married couples follow the IR1 or CR1 process instead.
For couples who are already married and living apart because of immigration processing, the spouse visa route is typically the path being considered.
From start to finish, the IR1/CR1 process is designed to verify the relationship, review financial sponsorship, and confirm that the immigrant spouse is eligible for permanent residence. While the exact timeline varies, most couples move through the same series of steps before the visa is issued.
The U.S. citizen spouse begins the process by filing Form I-130, Petition for Alien Relative, with USCIS.
The purpose of the petition is to establish that a valid marital relationship exists.
Supporting evidence often includes:
USCIS reviews the petition and supporting documentation. If additional information is needed, USCIS may issue a Request for Evidence (RFE).
Once approved, the case is forwarded to the National Visa Center (NVC).
The NVC assigns a case number and requests additional forms, fees, civil documents, and financial sponsorship documentation.
This stage typically includes:
Before the interview, the immigrant spouse must complete a medical examination with an authorized panel physician. Required vaccinations may also apply.
Once the case is complete, the interview is scheduled at the appropriate U.S. embassy or consulate.
For many applicants in Latin America, this may occur in:
If the visa is approved, the spouse can travel to the United States and enter as a permanent resident. The green card is then issued after arrival.
Document preparation is one of the most important parts of the IR1/CR1 process. Missing records, incomplete forms, or inconsistencies between documents can delay a case, so it helps to gather key paperwork as early as possible rather than waiting for each stage to begin.
Although every case is different, applicants commonly need:
Original documents and certified translations may be required depending on the country and specific case. Many of the documents required throughout the IR1/CR1 process will be reviewed more than once by different government agencies. Keeping organized copies and checking that names, dates, and personal information are consistent across records can be helpful.
Time and cost are not determined by a single application fee. The process involves separate stages administered by USCIS, the National Visa Center, and a U.S. embassy or consulate, each with its own processing requirements and associated expenses.
Processing times can vary depending on:
Unlike some immigration categories, the IR1 and CR1 process does not have a fixed timeline. Some cases move faster than others, while others can take well over a year from filing to visa issuance.
Common costs
While costs are not fixed and every case is unique, the typical expenses you can expect may include:
Government fees can change over time, so applicants should always verify the most updated costs directly through USCIS and the U.S. Department of State.
The consular interview is the final major step before a spouse visa can be issued. By this stage, the government has already reviewed the petition, supporting documents, financial sponsorship forms, and medical examination results. The interview gives a consular officer an opportunity to verify the information in the application and address any remaining questions.
While every interview is unique, the officer may ask questions about:
The goal of the interview is to confirm that the marriage is genuine and that all eligibility requirements are met. If the visa is approved, the consular officer typically keeps the passport temporarily so the immigrant visa can be issued.
Receiving an IR1 visa or CR1 visa is a major milestone, but it is only the beginning of establishing life together in the United States.
Many newly arrived immigrants need to:
A common challenge newly arrived immigrants face is opening a bank account before receiving a Social Security number.
For couples separated during the immigration process, Común offers remittance services for people in the United States who need to send money to family members in Latin America; they can do it directly from the app. This can be useful during the months of waiting between USCIS approval, NVC processing, and the visa interview.
When the immigrant spouse arrives in the United States, Común offers eligible customers the possibility of opening an account using a passport or more than 100 accepted Latin American IDs. Additionally, Común offers services for everyday payments, direct deposit acceptance available from day one, customer support in Spanish and a virtual debit card from day one of account opening.
The IR1 visa and CR1 visa process can feel complicated at first, but understanding and preparing for each stage can make the process feel more manageable.
For many immigrant families, the journey can include months of waiting, collecting documents, attending medical appointments, and preparing for the consular interview. The process requires patience, but it also creates a pathway for spouses to build a life together in the United States.
While you wait, Común can help you send money to your spouse in Latin America from the app. When they arrive, eligible customers can open an account with a passport or more than 100 accepted Latin American IDs so that they can begin managing everyday finances while settling into life in the United States.
The main difference is the length of the marriage. A CR1 visa is generally issued when the marriage is less than two years old, while an IR1 visa applies when the marriage has reached at least two years.
Processing times vary considerably depending on USCIS, the National Visa Center, and the consulate handling the case. Timelines should be verified through official government sources.
Costs commonly include government filing fees, visa processing fees, medical exams, vaccinations, translations, and travel expenses. The exact total varies by case and country.
Applicants commonly need a passport, marriage certificate, birth certificate, financial sponsorship documents, visa application forms, medical examination records, and evidence supporting the marriage.
Yes, after entering the United States as a permanent resident through an approved IR1 or CR1 visa.
A consular officer reviews the application and asks questions about the relationship, eligibility, and supporting documentation. The purpose is to verify the information already submitted.
Some couples complete the process on their own, while others seek professional guidance. The decision often depends on the complexity of the case, prior immigration history, or other legal considerations.
The IR1 and CR1 categories are generally associated with consular processing abroad. Individuals already in the United States may have other immigration options depending on their circumstances. Because situations vary, reviewing official USCIS guidance is important.

Starting today, all Común customers will have access to free international money transfers for a limited time. Afterward, the fee will start at $2.99.
Sending international money transfers, also known as remittances, can be costly given the additional fees consumers face from financial institutions and other non-bank service providers. This is a particularly relevant area for the Latino community. According to a recent report from the Inter-American Development Bank, remittances to Latin America and the Caribbean reached a record high in 2023, reaching $155 billion, a 9.5% increase compared with 2022 ($142 billion). At Común, we believe remittance sending should not come at a high cost. Today, we are pleased to announce that all Común customers can send money to Latin America at no cost for a limited time. Afterward, the fee will start at $2.99, lower than what other providers offer.
To put into perspective how much Latinos can save in fees with international money transfers, Común analyzed and compared the cost of using providers such as Western Union or Remitly versus Común. In addition, we wanted to know how customers interact with Común’s new money transfer feature, which became available in March 2024.
For the analysis, we first examined the average number of remittance transfers Común customers send monthly; in this case, it was two transfers. Using Común customer insights, the report analyzed the most common countries to which customers send money. Finally, we examined how much a consumer could save in remittance fees over a one-year and five-year period if they used Común versus Western Union or Remitly, assuming they sent two money transfers each month.

Checking account
8 min de lectura
A bank account is a financial account a customer holds at a bank. A bank account lets customers deposit and withdraw money, as well as write checks. That's why it's also called a checking account.
The advantages of having a bank account include:
How Do You Open a Bank Account?
Opening a bank account is relatively easy. You'll need to provide some personal information, like your name, date of birth, and address. You'll also be asked for ID — usually a Social Security Number (SSN) is enough. More modern banks, like Común, let you replace your SSN with a passport or consular ID. You may also be asked for documentation proving your address.
The Different Types of Bank Accounts Available
There are different bank accounts to choose from. The most common type is the checking account, which lets you deposit and withdraw money and write checks. A checking account is a great option if you want easy access to your money without carrying cash, since your account's debit card lets you pay at any business.
Another common type of bank account is the savings account. Savings accounts let you save money and earn interest on your deposits. It's a great option if you want to build up your savings over time.

These include some of the most popular banks in the United States: Bank of America, JPMorgan Chase, Citigroup, and Wells Fargo. Here are some of the fees they charge:
Certain banks also limit Spanish-language support in their digital interfaces or customer service centers. Be sure to research the fees charged and the language support offered before opening an account with any bank.

Reaching the point where you're preparing for the citizenship exam is already a major milestone. It reflects time, effort, and a commitment to building your future in the United States.
In this guide, you'll find the 100 civic questions for the U.S. Citizenship exam provided by the U.S. Citizenship and Immigration Services (USCIS), the government agency that reviews and processes citizenship applications. These are the questions from the civics test, translated into Spanish with their answers and organized by category aimed to support you while you prepare. The exam is administered by USCIS and is oral, not written. You'll be asked up to 10 questions out of the 100.
The U.S. citizenship exam generally consists of two parts, an English test and a civics test. Understanding how each one of them works could make the process feel more manageable. The English evaluation is conducted through an interview, in which an officer evaluates your English language skills through simple speaking, reading, and writing exercises. In the civics portion, the officer asks up to 10 questions out of a list of 100. They are about U.S. history, government, geography and holidays. To pass the test you must answer at least 6 of them correctly. It is important to consider that this entire part of the exam is oral.
If you do not pass a section the first time, you will usually have a second opportunity to retake the failed portion within 60 to 90 days. To start the application for citizenship, you must submit a form called Form N-400, which is the official application for naturalization, and as of 2026, the filing cost is $760, however, fees are subject to change.
If you are 65 or older and have been a permanent resident for at least 20 years, you may qualify to take the civics test in Spanish. This special rule, provided by USCIS, is designed to make the process more accessible for long-term residents. In this case, you do not need to study all 100 questions, you only need to study 20 of the 100 questions. In our list we will mark them with an asterisk (*). It is recommended to always consult and review the specific requirements of your own case with the corresponding authorities.
Here you will find the 100 official questions that USCIS may ask you during your citizenship exam, along with their answers in Spanish. However, keep in mind that the actual interview is conducted in English, unless you qualify for an exemption.

During the civics portion, an officer from USCIS will ask up to 10 questions out of a list of 100. You need to answer at least 6 correctly to pass this part of the test.
The exam is conducted in English, including both the English and civics portions. However, applicants who qualify for the 65/20 exemption can take the civics test in Spanish. Make sure you verify if the exemption applies in your specific case with the corresponding authorities.
If you fail either the English or civics section, you are given a second opportunity to retake the part you did not pass. This second interview typically takes place within 60 to 90 days.
The exam itself does not have a separate fee, but it is included in the naturalization application. As of 2026, the cost to file Form N-400 is $760, though it's always a good idea to verify updates directly with USCIS.
The list of questions is updated occasionally by USCIS. The current version is based on the reinstated 2008 civics test, which remains the standard as of 2026.
Yes, many applicants study the questions in Spanish to better understand the content. However, the actual exam is conducted in English unless you qualify for an exemption like the 65/20 rule.
Preparing for the citizenship test doesn't have to feel overwhelming. Approaching it with a plan and consistency could be the key for a smoother experience. Here are some general tips we've enlisted for preparing for your citizenship exam:
Study by category, avoid trying to learn all of them at once.
Break the 100 questions into topics like history, government, and geography. This makes it easier to understand patterns instead of trying to memorize everything in one go.
Practice your answers out loud.
The exam is oral, so it's important to get comfortable saying your answers, not just recognizing them. This helps with confidence during the interview.
Start with questions that change.
Aim to focus first on answers that can vary, like the current president or your state's senators. Learning these early helps you avoid confusion later in the process.
Use flashcards and try to study with someone.
Flashcards are a great tool for repetition and reinforcing memory. If possible try practicing with a friend or family member to simulate the real experience of being asked questions.
Don't panic if you don't know everything.
You don't need a perfect score. You only need to answer 6 out of 10 questions correctly, so focus on being consistent, not perfect.

Being far from family and friends is one of the main challenges faced by immigrants living in the United States. Fortunately, sending mail is a way to maintain the bond with loved ones across borders.
In the United States there are several options for sending packages to Mexico. Below we explain the features of each service so you can choose the one that best fits your budget and needs.
There are two shipping options from the United States to Mexico: through USPS or private courier companies.
These are the main United States Postal Service (USPS) shipping services and their characteristics. Please refer to their website for the most up-to-date information.
There are also private courier company alternatives that offer excellent service and additional shipping options. Please refer to each courier’s website for most up-to-date information.
Below is a comparison table to help you view the information more clearly.

As seen in the previous section, it is impossible to precisely estimate the shipping cost and time for each courier service from the U.S. to Mexico. Several factors influence the final result, explained below.
This is the main factor that affects the final cost of an international shipment — the heavier and bulkier the package, the higher the rate. Also check whether the company has a maximum shipping weight.
The final destination also matters. Sending a package to Mexico City is usually cheaper than to a rural area.
Express or priority shipping services are faster and therefore more expensive.
If you ship during Christmas, New Year or high-demand dates, expect possible delays or extra costs.
Before going to your preferred shipping carrier’s office, make sure all information is ready to avoid delays and ensure your package reaches your loved ones without issues.
Make sure your package does not contain restricted items for entry into Mexico, such as perishable food, flammable liquids or counterfeit goods. If unsure, check customs rules.
Use a proper box or purchase one at the post office. If the contents are fragile, protect them well and place the label correctly when closing the box.
Double-check as many times as needed that recipient details (name, ZIP code, neighborhood) are accurate. Even small errors can send a package to the wrong place.
Finally, keep the tracking number and receipt; they let you track the package and clarify any issues if needed.
We understand how important it is for immigrants to send packages to Mexico from the United States. More than a packaged product, it represents birthday gifts, greetings from afar, and fulfilled dreams for the people you love most.
That’s why it’s important to follow these tips when sending a package to Mexico.
Sending packages to your loved ones in Mexico is a way to show them they’re still important to you. That’s why planning your shipments—and your finances—is essential.
Get to know Común, the digital platform that helps immigrants manage their money in the most accessible way, as you can open an account using a qualifying official identification from your home country.
Just as your packages travel with care, Común supports your financial well-being.
Open your account with Común and stay connected with your loved ones through remittances.
If you still have questions, check the following section.
It depends on the courier company, but in general, an express service takes 3 to 5 business days.
When you send your package, you’ll receive a tracking number so you can follow it until it reaches its destination. Some courier options only provide tracking until it leaves the United States.
The USPS First-Class Package International Service is ideal for economical shipments, though the delivery time is usually longer.

Immigration procedures in the United States are often exhausting and confusing because of the number of requirements and the associated wait times.
You don’t have to feel alone during these processes: you can rely on a recommendation letter, which gathers family, community, or workplace support from people who truly trust your integrity and are willing to offer genuine backing that could bear on USCIS’s final decision.
Below is a user-friendly, practical guide on how to write an immigration recommendation letter, what it should include, mistakes to avoid, sample letters, and tips to convey credibility and improve your chances in a visa or Green Card process.
A recommendation letter is a personal document that supports U.S. immigration processes and is valued by USCIS. It serves as testimonial evidence of the applicant’s moral character, work ethic, and community contribution.
This supporting letter may be requested to complement documentation for various proceedings:
Applicants commonly must show “good moral character,” employment stability, and community ties.
The letter helps reinforce the applicant’s credibility and show they have support in the United States as a contributing community member.
Professionals or researchers often need a recommendation letter from expert peers to substantiate their track record and expertise.
Recommendation letters are not always requested, but they can support evidence of the applicant’s good conduct.
Don’t confuse this with an employment or academic letter; the purpose of an immigration recommendation letter is to attest to the applicant’s good behavior and moral character.
An immigration recommendation letter should be written by someone with a genuine, close relationship to the applicant who can attest to their positive impact—through family, social, or workplace ties.
These are the main profiles you can ask for a recommendation letter:
They can testify to the applicant’s role in the family and commitment to loved ones.
A close friend can focus on qualities like loyalty, honesty, and trustworthiness to emphasize the applicant’s human side.
They provide key testimony of the applicant’s work ethic and professional responsibility.
These individuals can speak to the applicant’s community involvement and positive impact.
Keep in mind that what matters most is not the recommender’s title, but their sincerity and credibility in vouching for the applicant’s reputation.
Although an immigration recommendation letter focuses on the applicant’s ethics and moral character, it is still a document evaluated for order and formality by U.S. authorities.
For that reason, be sure to include the following details.
Include the applicant’s full name, address, date, and a formal salutation to USCIS or the relevant authority.
The sender should state their full name and then explain their relationship to the applicant, how long they’ve known them, and the letter’s purpose.
This is the most important part and should reflect aspects such as:
Include concrete examples to reinforce credibility, such as: “Alicia Martínez is known in the community as someone who looks out for others’ well-being, like the times she has actively taken part in trash-collection programs and efforts to help homeless children.”
The sender should reaffirm support for the applicant and be open to being contacted to clarify any point, so contact details are necessary.
At the end, they should include their name and handwritten signature.
Below is a reference letter template to make drafting your document easier.
Sender’s full name
Address
Phone number
Date
To the attention of U.S. Citizenship and Immigration Services (USCIS):
My name is [Sender’s name], and I have known [Applicant’s name] for [number of years] through our professional relationship at [describe job title and company]. I am honored to provide my testimony in support of their U.S. immigration process.
Over the time I have known them, I have observed qualities such as punctuality in reporting to work and professionalism toward both colleagues and clients.
I am confident that [the applicant] will be a valuable member of U.S. society because of their human values and professional capabilities.
I remain at your disposal and include my contact information in case any questions arise.
[Signature][Full name]
You can use this example as a base, but you should adapt it to the relationship between you and the recommender and add any additional information to convey authenticity and sincerity. Be sure to include the introduction, qualities, examples, and a formal closing.
Here we’ve shown what an immigration support letter is and how to write one in Spanish, who can write it, its structure, and a practical example.
The main objective of a recommendation letter is to support you in U.S. immigration procedures; likewise, Común supports your financial life upon arrival in the country.

If you still have questions, see the section below:
There is no specific number. A single well-written letter may be sufficient. For extraordinary-ability visas or National Interest Waivers (NIW), more than four may be required to support the applicant’s professional record.
You can ask an immigration attorney to prepare a statement explaining why no one is available to provide a letter.
Ideally, submit the letter in English or include a certified translation to avoid issues during the visa application.

The bank routing number, or ABA Routing Number, is essential information for making money transfers. It is a 9-digit code used to identify each financial institution in the United States.
This code is so important because it ensures that electronic transactions are carried out correctly and that funds reach the designated bank.
In this article, we offer a complete guide to help you understand what a bank routing number is, what it does, where to find it, and how it is used in everyday electronic financial transactions.
An ABA routing number, or transit routing number, is a unique 9-digit code that serves as an identifier for each financial institution in the United States.
It differs from a bank account number in that an account number is personal, valid for the use of a single user only. By contrast, the routing number is a unique identifier for banks, credit unions, and digital banks.
The primary function of the routing number is to allow financial institutions to precisely identify which bank to send to or receive from during routine operations such as direct deposit of payroll, automatic payments (ACH), and electronic transfers.
It is important to note that this code is different from a bank account number and is not equivalent to the IBAN (International Bank Account Number), which is a set of numbers used especially in Europe to identify international bank accounts and is composed of the country code, check digits (the checksum of the bank account number), and a bank account number.
In the United States, however, the SWIFT/BIC code is used for international money transfers, not the IBAN.
Here are some crucial functions of the bank routing number in digital transactions.
The bank routing number helps prevent errors when identifying a specific bank and processing a transfer from one institution to another, even when they have similar names or many branches across the country.
This code is also indispensable so that ACH systems and wire transfers can send funds to the correct destination, quickly and securely.
The ABA number is also essential for employers to make direct deposits, using that code together with the checking account number, without the need for checks or cash.
To set up automated payments for services such as electricity, water, and online subscriptions, you must provide the bank routing number so the billing system can process the transaction automatically.
This number is also indispensable for transactions involving multiple financial institutions, such as interbank transfers or check clearing.
By now, the importance of the ABA number is clear. But how do you find a bank routing code? Knowing this information is the first step to making transfers correctly.
Likewise, it is essential to understand how to find your bank account number and to tell one number from the other to avoid confusion.
The routing number consists of 9 digits and identifies the bank. The account number has usually 10 to 12 digits and identifies the individual account within the bank.
To find your account number, look at the bottom of a check; it is the series of numbers that follows the routing number. You can also find it at the top of a statement or directly in the mobile application.
It is essential to make sure you have the correct routing number before making a transfer. Therefore, it is advisable to confirm it directly with your financial institution to avoid errors.
Many users ask where to find the routing number on a physical debit card. However, the routing number is not printed on such instrument because it is intended for digital transfers, not for payments at physical merchants.
These are the most common places to find the routing number for your bank or financial institution.
On your checks
Check the lower left corner of your personal or business checks; the routing number is the 9 digits shown there.Another relevant detail is the check number, which is usually at the top.
Mobile application
Another way to find this code is to access your mobile application and go to the transfers or direct deposit information section.
Bank statements
Check your latest bank statement, whether physical or digital; the routing number may appear in a section of that document.
Direct contact with your bank
If you have any doubt about the routing number, you can contact your bank by phone or visit a branch so they can clarify any questions before you make a bank transfer.
Throughout this article, we have learned the importance of both the bank routing number and the bank account number in the U.S. financial system. Both are indispensable for carrying out fast and secure digital transactions.
Being clear about what a bank’s ABA number is not only lets you carry out digital transactions with ease but also gives you financial autonomy to allocate your resources toward the services you need for your well-being.
The U.S. financial system can seem complicated, especially for immigrant communities. That is why Comun seeks to streamline processes and offer transactions without complications.
