Applying for a credit card in the United States as an immigrant is possible, even if you don't have a Social Security number (SSN) or established credit history. This guide provides general information about the process and shares helpful tips.
Applying for a credit card in the U.S. is generally a straightforward process. Issuers typically request documentation for identity verification and risk assessment purposes. Requirements may vary by issuer, but you can generally expect the following:
Identification
Tax ID number
You'll typically need one of the following: SSN or ITIN (Individual Taxpayer Identification Number) issued by the IRS. It's important to note that not all credit card issuers accept ITINs. However, some financial institutions and fintech providers may offer alternatives.
Income information
Credit history
Contact information
Yes. Some credit card issuers accept an ITIN instead of a Social Security Number. You can apply for an ITIN by submitting Form W-7 to the IRS.
It is recommended to look for service providers whose requirements match your current needs and documentation. For example, you may be able to open an account with Común using more than 100 valid Latin American IDs, which can be a helpful first step before applying for a credit card.
Before applying for credit, while not always required, it is generally recommended to open a debit account in the U.S. Having one may improve your chances of approval and help simplify the process. It can also help demonstrate income activity and provide a way to make payments on your credit account.
Look for service providers whose requirements align with your current documentation status. For example, some traditional banks may accept an ITIN to open a debit account. Others, such as Común, offer the ability to open a debit account online with more than 100 valid Latin American IDs. Visit comun.app to learn more.
To begin establishing a financial footprint in the U.S., it is often suggested to use a debit account consistently. This may include receiving direct deposits and maintaining regular account activity. While this does not create a credit history on its own, it may help establish a relationship with financial institutions and may support access to credit-building products.
Secured credit cards:
These cards typically require a refundable deposit, for example, $200. The deposit usually becomes your credit limit. This structure helps reduce risk for the issuer and may make approval more accessible.
Credit cards for individuals with limited or no credit history:
These credit cards are designed for individuals without an established credit history. They may not require a deposit but can have stricter approval criteria. Some issuers may offer products that accept an ITIN.
To submit your application, depending on the issuer you may apply online or at a bank branch. You will typically be required to provide personal details, such as your name, address, date of birth, an SSN or ITIN and your income information.
It is generally recommended to avoid submitting multiple applications in a short period of time, as each application may result in a 'hard inquiry' which can temporarily impact your credit score.
Debit card:
Credit card:
You may generate your first credit score within approximately 3 to 6 months after opening a credit account.
In most cases, to apply for a credit card you'll need some form of identification, such as a passport, and an ITIN. Some institutions offer options for individuals without an SSN, but applications without any documentation are generally not accepted.
A credit score is a number that reflects how you manage credit, based on your payment history and use of borrowed money.
No. Lenders generally don't deny applications based on immigration status alone. However, an application may not be approved if you don't have a credit history, sufficient income, or the required identification requested by the issuer.
In most cases, no. Most U.S. lenders don't have access to international credit data, so you'll need to start building credit history in the U.S.
Starting somewhere can make the process feel more manageable. For many people, building credit in the U.S. begins with something simple such as opening a debit account. Común offers a debit account that can be opened with more than 100 valid Latin American IDs, with an app available in Spanish. Visit comun.app to learn more.

Have you just obtained your permanent residence in the United States? Without a doubt, it’s a great achievement for every immigrant who has gone through the immigration process for a long time, though it also comes with a series of responsibilities and restrictions.
A recurring issue within the immigrant community is the general lack of awareness about the risks that can affect their legal status if they don’t act appropriately in the country.
In this article, we aim to keep you informed about these restrictions and provide practical advice to maintain your permanent residence smoothly.
The first thing you should understand is that being a resident is not the same as being a U.S. citizen, as there are clear legal differences that set them apart.
These are the main restrictions you should keep in mind.
Unlike U.S. citizenship, permanent resident status does not grant the right to participate in federal or state elections, which is a disadvantage in exercising voting rights.
Although permanent residents can work for the U.S. government, some positions are only available to citizens, particularly those related to national security or public trust roles.
While obeying the law is mandatory regardless of your immigration status, it’s important to remember that committing crimes such as fraud or drug trafficking can lead to the revocation of your Green Card.
One of the key requirements you must keep in mind from the moment you began your Green Card process is the obligation to maintain continuous residence in the United States before and after approval.
Keep these risk scenarios in mind to avoid problems with U.S. immigration authorities.
It is advisable to plan your trips abroad in advance and, if necessary, obtain a reentry permit before leaving. Also, stay up to date with your tax payments and seek legal advice if needed.
One of the main advantages of having a Green Card is the ability to sponsor family members for the same status. However, unlike U.S. citizens, residents have access to limited eligibility categories.
Although permanent residence offers certain benefits for holders, these restrictions can be frustrating for immigrants seeking family reunification hindered by regulations.
It’s true that there are risks that can lead to losing your permanent residence, but most can be avoided with good practices and responsibility.
Keep these tips in mind to avoid problems with the U.S. government.
Stay current with your annual tax filings; remember that the deadline is usually April 15 each year. It is essential to meet this requirement, even if you spend time outside the country, to demonstrate your responsibility as a permanent resident.
It is essential that your main residence is in the United States and that you can show clear ties in the country, such as work, studies, or family.
As mentioned before, being away for more than 6 months may be interpreted as abandoning permanent residence. Try to leave the country only in emergencies, after applying for Form I-131.
After 5 years as a permanent resident without extended absences and meeting other legal requirements, you can apply for citizenship and remove these restrictions.
Although naturalization is a long process with several steps, it is the most practical path to long-term stability in the country and full rights.
In this article, we explained the “fine print” of the permanent resident card, showing you the risk factors that could lead to losing your status, as well as its benefits.
A common concern for immigrants seeking permanent residence is staying connected with their loved ones despite the distance. Común is the fintech platform that helps you organize your money and send support easily.
Discover all the benefits of Común!
Open your account with Común today and manage your money in the U.S. with clarity and confidence.
If you still have questions, check the following section.
The Green Card, or permanent resident card, is the physical document that certifies that a person holds lawful permanent residence. Residency, on the other hand, is the status granting the right to remain in the country indefinitely.
The Green Card is valid for 10 years and can be renewed indefinitely as long as requirements are met. For conditional residency, it lasts 2 years, after which you must apply to remove the condition to renew it for 10 years.
If you don’t renew your permanent residence, your status remains valid, but you might face issues reentering the country, at work, or when handling legal procedures. It’s best to keep this document current to avoid complications.

One way to improve personal finances and optimize expenses is to apply modern, automated savings alternatives linked to daily purchases through various payment methods.
Los programas de recompensas con reembolso son una alternativa para que tu dinero rinda más, ya que ofrecen recompensas que te permiten obtener reembolsos en tus compras.
There are different ways to access these types of benefits: through automatic promotions from some credit cards, shopping platforms that reward users for shopping at their partner stores, and certain mobile applications that credit cashback for purchases like fuel.
Knowing and applying these strategies will help you improve your financial management and reduce your worries. Comun is the platform that helps you improve your financial relationship and make your life easier.
Below, we’ll explain how cashback reward works and share some tips to get the most out of it with the right financial platforms.
Cashback can be understood as a discount on your purchases. You earn cashback after buying a qualifying product or at a participating store.
Cashback appears in everyday purchases — for example, when you go to a café and pay with an eligible card, when you shop through an app that offers this benefit, or when you pay for gas with a cashback-enabled card.
Although the ultimate goal of cashback is to reduce part of the cost, it has some differences compared to traditional discounts.
Cashback Reward
Traditional discounts
Definition
Returns a percentage of your purchases after you make them.
Reduces a product’s price before purchase.
Advantages
Disadvantages
The cashback reward can take several days or weeks to be credited. Available only with participating cards or mobile apps.
The cashback reward varies depending on the financial institution or program offering it. To calculate it, use the following formula if cashback reward is by percentage:
Total Cashback Reward = (purchase amount) × (cashback percentage)
For example, if your debit or credit card offers 2% cashback and you spend $100, you get $2 back.
Here are the some of the ways to receive the cashback reward, depending on the program:
Cashback reward is a very useful tool to make the most of every dollar spent, saving amounts that might seem small at first but make a difference later when buying essentials.
Therefore, cashback reward encourages financial education by promoting consistency and smart shopping habits.
Here are some practical advantages of cashback reward:
Remember that consistency is key when using cashback reward to ease future expenses such as gas, groceries, or medicine — and to increase your ability to save and send more money to your loved ones in your home country.
Using cashback reward is itself a smart way to handle daily purchases. Keep these tips in mind to make the most of this benefit.
Use cashback reward only for purchases already included in your budget. This allows you to earn rewards from items you always buy, without falling into poor spending habits.
The fact that a product offers a cashback reward, no matter how high, isn’t reason enough to buy it if you don’t really need it.
It’s advisable to track how much cashback you earned each month and ensure it’s credited back correctly, which helps you know exactly how much you’re saving and motivates you to maintain good financial habits.
You can use spreadsheets or cashback reward mobile apps that include financial management tools to help with this.
In this article, we explained what cashback reward means, its benefits, how it works, and ways to use it wisely.
The habit of saving is essential, especially for immigrants living in the United States who seek to improve their quality of life and that of their families. While cashback reward helps optimize regular purchases, Comun simplifies financial management through a comprehensive platform.
Comun is the financial platform designed to ease financial management for immigrants in the United States.
Discover all the benefits Comun has for you!
Remember that managing the savings you earn through cashback reward will allow you to support your family’s projects and goals.
Turn your cashback reward into more opportunities for you and your family.
If you still have questions, check the section below.
Yes, cashback reward is designed to give you a percentage back from everyday purchases such as gas, groceries, and public transportation. However, it’s not recommended to use cashback reward as motivation to make unnecessary purchases.
Although credit cards are one of the most common ways to earn cashback reward, they are not required — there are other alternatives such as debit cards with cashback or digital accounts, as well as platforms like Rakuten, Ibotta, Upside, or Honey.
Cashback on credit cards is a way to earn a percentage of cashback for your purchases. Some financial institutions also offer bonuses or additional benefits. If you use a credit card, make sure to pay the full balance to avoid interest charges.
It’s a benefit that gives you a percentage of your purchases back directly to your debit card.

International Money Transfers

Every year, people all over the United States send remittances to support their family and friends back home. These transfers are more than just simple transactions, these are the economic lifeline for them. This is why choosing the right service provider for your remittances based on your needs is key to ensuring you and your loved ones have the support you need.
What is a remittance?
Simply put remittances are money transfers made by people who live and work in one country to family members, friends, or other beneficiaries who are residing in another country.
Sending a remittance from the U.S. follows a fairly standard process, these are the steps regardless of who is the remittance service provider:
The combination of fees + exchange rate markup is what ultimately determines the real cost of the remittances transfer. Many remittance providers advertise low fees when their business gains are achieved by offering a much weaker exchange rate, which results in reducing the amount your recipient actually receives.
The U.S. remittance service provider market is diverse, and providers generally fall into the following categories:
These are the traditional remittance companies with physical locations for in-person payments and cash pickups.
Examples: MoneyGram, Western Union, Walmart (MoneyGram at Walmart).
Pros: Physical accessibility, ideal for people without bank accounts.
Cons: Often higher service fees, a slower process, and often has exchange-rate markups.
Some financial institutions offer international wire transfers through SWIFT processes for remittance programs.
Pros: Physical locations, direct bank-to-bank transfers.
Cons: Requires a bank account, usually the most expensive option (as SWIFT processes tend to have costly fees and exchange rates) and it could require longer processing times.
These companies operate entirely online or through mobile apps. They can be faster and more transparent.
Examples: Remitly, Felix, Comun, etc.
Pros: Convenience, speed, competitive fees, trackable transfers.
Cons: Limited cash pickup options in some regions.
Choosing the right remittance service provider can have a significant impact on how much money actually reaches your loved ones. Between varying fees, differences in the exchange rate, documentation requirements, and the growing list of additional services, not all remittance providers offer the same services nor require the same things. Whether you send money home occasionally or on a weekly basis, it is important to choose a remittance provider that maximizes the value of what your loved ones receive.
Every remittance provider has some form of fees for providing their services, however not all fees are presented the same way (this is why it's important to fully understand the costs associated with your remittance).
What could be an unexpected fee?
What to look for?
In many cases, the cheapest provider isn’t the one with the lowest visible fee. It could be the one offering the most competitive exchange rate or a fixed fee that makes sense with your transfer activity. The best service provider will always be one that serves the specific needs you have.
The exchange rate (or tipo de cambio) used by the provider determines how many pesos, quetzales, soles, or other currency your recipient will receive. When sending money abroad, senders can sometimes focus only on the visible fee (for example, a charge of $3.99 per transfer). But in many cases, the biggest cost can come in the exchange rate. If two companies offer the same fee but one has a weaker exchange rate, your family may receive less money.
For example: A difference of choosing an exchange rate with just 1 mexican peso less per USD could mean that the recipient would get $100 mexican pesos less on a $100 USD remittance.
Understanding the real costs of your remittance is essential to choosing the best remittance provider.
What questions can I ask myself before choosing the right remittances service provider?
What could be something to look out for?
Even a small difference in the exchange rate can significantly reduce the final amount your family or friends receive if you send a lot.
Each remittance provider must comply with U.S. financial regulations, but their onboarding requirements vary from service provider to service provider.
What are some common documentation steps or documents needed?
What to look for?
If a provider asks for excessive documentation or makes the process confusing, consider choosing one with smoother compliance systems. For example, some remittance services accept documentation without a United States passport when the sender can demonstrate residency in the United States.
While some people prioritize low cost, others prioritize speed. This is completely impacted by the recipient's needs back home.
What can I focus on to ensure my transfer arrives quickly and safely?
When urgency hits speed matters, but always make sure your money is safe.
Choosing a remittance provider also requires confidence in the company’s ability to protect both your information and funds.
What are some key indicators of a trustworthy service provider?
To keep your money safe it is important to consider avoiding remittance providers with unclear credentials or repeated complaints about blocked transfers and delayed payouts.
A remittance provider is more than just a money-sending tool. Many now offer value-added features that can save you time or money.
Common additional services
What to look for?
Extra services should add convenience not complexity. For example, at Comun you can either use your own debit card to fund the remittance, or open a Comun checking account if you don’t have a debit card.
There’s no one-size-fits-all for a remittance service provider. Some people value speed, others care about the costs, while others need in-person services or cash pickup locations. To get the most out of your next transfer, focus on what matters to you whether it’s:
Taking a few minutes to compare the options with different service providers can make a significant difference in what your family and friends receive and how you optimize your finances according to your needs.
Comun offers remittances services where you can either use your own debit card, or open a checking account with Comun if you don’t have a debit card. With Comun there are no annual nor monthly fees. Furthermore, Comun’s services are available in Spanish. Download our app or reach out if you’d like to learn more about Comun.

Living and working abroad? Remittances might be for you if you want to send money to family members, friends, or other beneficiaries in another country.
Remittance is money transfers from one person to another, usually across borders. They are most commonly sent by immigrants who send a portion of their income to support their families back home. However, remittances can also be personal gifts, financial support, or payments between relatives or friends who maintain social or economic ties despite the distance.
Remittances can be money transfers, however what is commonly understood as remittances are voluntary person-to-person transfers, usually between family members. For example: a worker in Texas sending money to their parents in Mexico, a nurse in Florida sending money to her siblings in Honduras, or a student helping their grandparents in Guatemala. Bank transfers on the other hand, can include payments between companies, international trade payments, foreign direct investment, loans between corporations, or government aid.
In summary, remittances are personal, cross-border, person-to-person transfers.
Today there are more options than ever to send money to Latin America from the U.S. The process is usually very simple:
Your remittance service provider can be a financial mobile application, a traditional bank like Wells Fargo, a specialized money transfer service like Western Union or MoneyGram, or a fintech company like Remitly.
Each company offers different delivery options depending on their services and local partnerships. Delivery options vary in cost depending on the provider and the urgency.
The amount received by the recipient varies by the exchange rate used by the provider and the service fee they charge. Some companies might charge no fees, but their business model relies on the exchange rate markup.
With so many options available, remittances can be paid with various methods including:
It can take minutes to days for the recipient to receive the funds, depending on how the funds are received or by the type of remittance provider used to send the remittance.
The total cost depends on two main factors:
This is the fee the provider charges to send the remittance. It can range from $0 to over $20 USD per transaction depending on the provider and payment method used.
Some companies have different exchange rates, making the remittance more expensive even if the service fee is advertised as “$0.” Sometimes the fee for the service provider is included within the added margins in exchange rates.
These may include cash pickup fees, limits for high transaction amounts, or fees charged by participating banks. It is important to understand the fees in remittance costs to be able to manage your funds in a way that makes sense to you.
To choose the best option, you can always consider:
In the U.S., there are several types of companies offering remittance services:
Traditional money transfer companies, for example: Western Union, MoneyGram, and Ria Money Transfer. These companies have physical branches in many locations. Fees could be higher than alternatives and the exchange rates can be less competitive.
Traditional banks: However, not all banks provide this service, but institutions like Bank of America and Wells Fargo allow international transfers through online banking or in-branch. However, it is important to consider that the fees can reach up to $60 USD depending on the bank, and transfers can take up to 5 business days. For this option, a bank account with the institution is needed or cash transfers are done directly at a branch.
Digital first companies (apps): Examples include Remitly, Wise, WorldRemit, and Xoom (from PayPal). These companies can offer more competitive pricing and faster transfers. These options are presented as an alternative to traditional banks or Western Union. Comun is one of these platforms, combining a fintech experience with extra benefits like a digital account and an easy-to-use app available in Spanish.
Convenience stores: For example, Walmart offers in-person remittance services. For example companies like Comun can also offer services like cash funding in retails or ATM locations. With a Comun open account you can deposit cash at one of over 90,000 retail locations (Walmart, 7-Eleven, Walgreens, and more) and then complete the remittances conveniently from your app.
Requirements vary by provider and they depend on:
-How the remittance is sent, and
-How the remittance is received.
For example, if sending money for cash pickup, the most important information is the recipient’s full legal name as it appears on their official ID, since they’ll potentially need to present it to pick up the money.
For a bank-to-bank international transfer, the essential information includes the bank details for the receiving account.
Traditional banks and companies like Western Union generally require:
Sending a remittance with Comun is very simple. You have two options at the palm of your hand, you can send it through the app or via WhatsApp. Here’s a detailed step by step on how to do it:
Through the Comun App
*To add a recipient, you’ll need: full name as on their ID, phone number, and—if sending a bank transfer—their bank details.
To make sure your get the best out of your hard-earned money, it is recommended to keep some good practices in mind:
Ideally, choose a provider that uses an exchange rate as close as possible to the real market rate as this impacts the actual amount your recipient will receive. Understanding transaction costs can help make better financial decisions for your needs.
2. Look for transparent, fixed fees
Comparing fees can be confusing because many services use variable pricing based on multiple factors. Ideally it is recommended to choose a provider that offers fixed fees and transparent pricing.
Keep in mind that transfers may be delayed during weekends or holidays in either country, so processing times may be slower than on regular business days.

Having a driver’s license makes everyday tasks easier, such as going to work, the supermarket, school, medical appointments, and more. This process is especially important for immigrants living in the United States, as it gives them independence and stability in the country.
Although the process to obtain a driver’s license varies in each state, foreign nationals do have the possibility and the right to obtain one. Below, we explain all the details so you can get this permit soon.
If you have recently arrived in the United States and need to get around in your own car, you may temporarily use the driver’s license from your home country, as long as it is issued in English or accompanied by an international driving permit.
As a new driver in the United States, you must understand the difference between an international license and a local one: the former supplements your national license and allows you to drive in the U.S. for a few months; the latter is issued by the Department of Motor Vehicles (DMV) in each state and grants you a permanent permit to operate a motor vehicle in the country.
Regulations differ in each state: for example, in California you can drive with a valid foreign license until you become a resident. In contrast, in Texas your national license is valid for 90 days, and you must always carry your passport or visa.
The maximum time allowed to drive with a foreign license varies depending on each state’s local regulations. In general, the period can range from 30 days to one year, from the day you arrive until you establish yourself as a permanent resident.
If you plan to live in the United States for a longer period, you need a U.S. driver’s license to drive. It is also essential if you plan to buy a car.
Also, remember that in some states the period to drive with a foreign license is limited, so you should consider applying for a U.S. license before that deadline expires.
The requirements to obtain a driver’s license also vary by state, although the general structure is similar.
This is the documentation needed to obtain a driving permit in the United States.
Keep in mind that states such as New York and Illinois allow applicants to obtain a driver’s license without considering immigration status.
Learn here how to send money without a bank account.
Getting your driver’s license may seem like a complex and tedious process. In reality, you only need to stay organized and take the time to understand the guidelines.
Before going to a DMV office, make sure to prepare the required documents. In the previous section we outlined what you generally need, but remember to check for variations in the state where you live.
Then, visit the DMV website and book an appointment. On the scheduled day, your documents will be reviewed and you will be given a date for the written exam.
The written exam evaluates your knowledge of traffic rules and road safety. Each state offers a driver’s manual to study for the test, and some are available in other languages, such as Spanish.
If you pass, you will receive a learner’s permit that will allow you to take the driving test under the guidance of an instructor.
The next step is probably the most challenging, as you must apply your theoretical knowledge in real driving practice. During the test, the instructor will evaluate your ability to follow traffic signs, park, turn, and follow safety rules.
Once you pass your driving test, you must pay a fee that varies by state. Initially, you will receive a temporary license and later receive your permanent license by mail.
The cost of a driver’s license in the United States depends on each state, but generally includes the cost of the written exam, driving test, and issuance. The validity also varies by state, but it is usually between 4 and 8 years.
Additionally, a positive update for immigrants is that more states are removing immigration status requirements to issue a driver’s license; this is the case in California, New York, and Illinois.
If you have questions about the specific requirements in your state, check the updates on the official DMV website.
Having a U.S. driver’s license represents another step toward achieving financial independence and making it easier to move around your city. Therefore, it is essential to understand the process to obtain one, as well as the differences in each state.
In other words, having a license simplifies and improves your life by making everyday tasks more accessible. Likewise, Comun is the financial platform that helps you manage your money safely and without complications.
Open your account with Comun and take the next step toward your independence in the United States. Manage your money with confidence, clarity, and support at every step.
If you still have questions, check the following section.
The duration varies depending on the state you are in, but generally ranges from three months to one year.
If your immigration status changes after you obtain your driver’s license, it is recommended to update your information at the DMV. You may need to apply for a new license or present updated immigration documentation.
Although the international driving permit (IDP) is accepted in most states, it must be accompanied by a valid national license. Additionally, there may be restrictions on how long it can be used in each state.
Yes, it is possible to apply for a driver’s license without an SSN in several states. In this case, you must present an ineligibility letter issued by the Social Security Administration (SSA).

Nowadays, making purchases with a credit or debit card in physical stores and online is an essential activity for acquiring everyday goods.
Security in these operations is essential. For this, these payment methods use the CVV or CVC code, which means Card Verification Value or Card Verification Code respectively, and its purpose is to verify that the cardholder has the physical card and to protect online and phone purchases.
Below, we will explain in detail what the CVV is, where to find it, the types of security codes, and tips to keep your cards secure.
If you are going to make purchases online or by phone, you will need to provide the security code of your debit or credit card to verify it belongs to you.
In most cases, the CVV is located on the back of the card and consists of 3 or 4 numbers.
Here is a quick guide to locating the verification code depending on the card type.
Card type
Where to find the CVV?
How many digits does it have?
Visa
Usually on the back, next to the magnetic stripe.
3
Mastercard
Usually on the back, next to the signature.
3
Discover
Usually on the back, to the right of the signature.
3
American Express
Usually on the front, next to the card number.
4
One way to strengthen security during electronic transactions is the use of a dynamic CVV, which is found in digital applications or cards and is valid only for a limited time to make a single purchase. This reduces the risk of misuse of your personal data if it is exposed.
The CVV number is a security lock that allows you to use your physical and digital cards with confidence that a third party cannot access your money.
These are the most important functions of this security code.
It is especially useful for protecting electronic operations by verifying that the cardholder is the one making the purchase.
When making an online purchase, you must enter the card’s CVV to validate the transaction. This process is more secure when using a dynamic CVV because it reduces the risk in case of fraud.
Unlike other data usually included on physical cards, such as the number and expiration date, the CVV is not stored in online store systems, so your data remains safe in case of potential identity theft.
The purpose of the CVV is to provide you with security and peace of mind when making online purchases.
You may notice different types of CVV since the name can vary depending on the card issuer.
These are the security codes most commonly used by financial institutions to protect users’ cards.
The CVV (Card Verification Value) is the security code created for Visa cards. It consists of 3 or 4 digits and is used to confirm that the person making the purchase actually has the card.
The CVC (Card Verification Code) is the version of the CVV used by Mastercard cards. It has the same function and a similar composition.
The CVV2 (Card Verification Value 2) is a digital version of the CVV used to provide greater protection in online purchases. While the traditional CVV is used during payments at card terminals, the CVV2 is requested to confirm remote transactions.
Some people avoid or minimize the use of physical or digital cards due to fear of having their personal data stolen and generating unauthorized charges. However, financial institutions and digital platforms currently offer the necessary security measures to protect your assets.
Thanks to the implementation of codes such as the CVV, the risk of experiencing a security incident is minimal and decreases even more when you have the right information to apply practical strategies like the following.
Bank cards are useful tools that require responsible and cautious use. Learning to use your card safely and confidently is also part of building financial stability.
This time we explained what the CVV or CVC is, why it is important, and gave you some tips to keep your checking accounts secure.
The security provided by the CVV is the same you need in all your financial operations, such as digital payments, cash deposits, and international money transfers. For this, you have Comun, the digital platform specially designed for immigrants living in the United States who want to manage their money safely and without complications, with clear and competitive fees.
Comun is the financial platform that truly understands your needs and offers fair, tailored solutions.
Open your Comun account and start managing your money in the United States with confidence. Send, receive, and monitor your expenses from the mobile app.
If you still have questions, check the following section.
It is not advisable to give your CVV to someone else, as they could make purchases not authorized by you. Make sure to protect your banking information so only you have access to it.
No, the card number consists of 16 digits and identifies the checking account. The CVV consists of 3 or 4 digits and verifies that the holder is the card owner.
In physical stores, it is not strictly necessary, as the purchase is validated with the chip and PIN. For online purchases, it is essential to enter the CVV to authorize the transaction.

Immigrants living in the United States should become familiar with several terms and procedures to ensure their long-term stay in the country.
One way to compile all the information related to your immigration process is through the A-Number or Alien Registration Number. This identifier is assigned by the Department of Homeland Security (DHS) to foreign nationals residing in the country.
It’s very important to know this information, as it serves as the identification number for your immigration file.
In this article, we’ll explain what the Alien Registration Number is, what it’s used for, and why it’s so important for immigration procedures.
The first step to identifying an A-Number is knowing that it always begins with the letter “A” and contains 8 or 9 digits.
The main function of this number is to allow USCIS and other agencies to quickly track immigration cases and applications related to each person.
Here are some examples of when the A-Number is used:
To locate your A-Number, you can check several official documents issued by USCIS or DHS, such as:
Below we break down how the A-Number appears on various official documents.

Location
Permanent Resident Card
On the front, next to “USCIS#” or “A#.”
Work Permit (EAD)

This is a unique number assigned only to individuals with formal and permanent files in U.S. immigration agencies, such as:
On the other hand, temporary visitors such as tourists, students, or non-immigrant visa holders do not receive an A-Number since their cases do not require a permanent immigration file.
The A-Number is a central identifier used in multiple immigration procedures needed to regularize your status in the country.
Here are the most common uses of the A-Number in immigration processes.
If you want to track the status of your pending applications, such as permanent residence, work permit, or adjustment of status, you need to enter your A-Number in the USCIS Case Status system.
This way, you can know exactly which stage your case is in and stay informed of updates to ensure your process stays on track.
It’s essential to keep your immigration records updated. If you change your address, phone number, or legal name, your A-Number will help you update your information.
This helps ensure you receive official notifications and avoid delays in important procedures.
Since the A-Number functions as a unique identifier, it also helps avoid confusion between applicants with the same or similar names.
Be sure to use your A-Number correctly when filling out forms or official documents so that all your information stays under the same file and saves time when searching for a document or specific information.
In short, this number helps simplify the immigration process for immigrants and provides a sense of security and control during procedures that can often cause stress and uncertainty.
If you don’t have an A-Number, remember that USCIS assigns one once you start an immigration process in the United States. If you already have one but can’t remember it, follow these tips to locate it.
Avoid using a fake A-Number, as this could cause problems with immigration authorities.
As you can see, the A-Number is essential to staying organized during immigration procedures. It helps keep your documents together in one file, making them easier to locate and reducing the risk of delays caused by mistakes.
Another important aspect of immigrant life in the U.S. is having the right tools to keep personal finances organized.
