What is proof of income and how does it work in the United States? Types of accepted documents for renting, loans, and credit applications.
8 min read

20 Nov 2025

As an immigrant in the United States, you have likely been asked for proof of income to complete a procedure such as obtaining a loan, renting an apartment, or verifying financial solvency and ability to pay.
Such proof is a document that verifies the amount of your income as well as its source.
This time, we explain what proof of income is in the USA, what it is for, how to make an income letter if you are paid in cash, and everything you need to know to handle your procedures in the United States without complications.
Broadly speaking, proof of income is an official or informal verification of how much money a person earns and the sources from which that income comes.
This document is commonly used for both salaried employees and independent or freelance workers.
These are the most common types of documents used to verify income:
This is an official document that serves as a payment receipt and is provided by the employer along with wages for the relevant pay period. It includes both parties’ details, base pay, hours worked, overtime (if applicable), and deductions for taxes.
The tax return is a document a person files annually with the Internal Revenue Service (IRS). It must include income earned, taxes withheld, deductions or credits, and the total tax due or refund.
This is a report issued by a bank or financial institution detailing a customer’s transactions and balances in their bank account over a given period. It serves as an official document to corroborate a person’s solvency as well as other personal data.
Having proof of income is very useful for various procedures in the United States, as well as to access helpful benefits and simplify your life—for example, signing a lease, obtaining a loan, and completing relevant immigration procedures. Proof of income is essential in these processes because it gives the requesting party assurance.
Landlords commonly request proof of income to sign a lease, as it helps ensure tenants can cover the monthly rent without delays.
Banks and other financial institutions usually verify applicants’ income before approving credit, since this reduces the risk of nonpayment or delinquency.
Immigration procedures—such as obtaining permanent residence—and other social security benefits also require proof of income. This is a measure implemented by the U.S. government to ensure applicants will not become a public charge.
Whether you have formal employment or are self-employed, there are several documents you can use as proof of income.
If you have a formal job, obtaining proof of income will be easier. As noted, you can present a pay stub, bank statement, or an employer letter.
If you are self-employed, verifying income may be a bit more challenging than for formal employees. In this case, you can present your annual tax return and bank statements.
If none of these options are available, you can draft an income letter, which should include the following information.
If you receive your pay in cash, you can generate formal proof of income.
The first option is to create a signed income letter. You can also keep an income log in a spreadsheet. To make the process easier, it is advisable to seek support from an accountant.
Fortunately, drafting an income-verification letter is not complicated, since it can be adapted to your work situation—even if you are paid in cash.
It is also a simple path for immigrants because it lets them use day-to-day documents.
Follow these steps to draft your income letter.
Any document that can help verify your income, even if it is not strictly a pay stub—such as a bank statement, fee receipts, invoices, etc.
Don’t forget to include your average income and signature.
It is very important to include your full name, address, and the dates that the declared income covers.
An accountant will help you formalize your letter and gain better control of your personal finances and tax obligations.
I, (full name), residing at (address), declare under penalty of perjury that I work as an independent contractor in the field of (description), with an average monthly income of (amount).
Copy this text and create your letter easily.
As you can see, proof of income is a formal document to verify a person’s income level as well as their ability to pay and financial solvency. You can use several documents for this purpose, such as a pay stub, annual tax return, and bank statement from traditional banks.

Checking account

A debit card is a bank card that lets you make purchases and withdraw money using funds available in your bank account. A debit card looks a lot like a credit card, but it works differently. When you use a debit card, the money is deducted directly from your bank account. That means you can only use the card if you have enough available funds — otherwise, the transaction won't go through.
Who Issues Debit Cards for Consumers?
Debit cards are issued by banks and are linked to individual checking accounts. You can get a debit card by opening a bank account at any bank or credit union that offers this service.
Many banking institutions also offer other digital services, like mobile and online banking, that let you manage your account over the internet or through a mobile device. In general, all banks offer services designed for people with different needs and income levels, giving nearly every adult access to banking.
Even though debit cards are easy to use, you should be careful with them. If you lose your card or it's stolen, report it to your bank immediately to prevent fraud or misuse. You should also regularly check your statements for fraudulent transactions or errors. With a bit of care, debit cards can be a useful tool for managing your money and making purchases online and in person.
How Can You Use Your Debit Card to Make Purchases or Withdraw Money From an ATM?
There are many ways to use a debit card to make purchases or withdraw money from an ATM.
To make a purchase, you can insert your card into the point-of-sale (POS) terminal and select "debit" as your payment method. Then enter your PIN and select the purchase amount.
To withdraw money from an ATM, insert your card into the machine's slot and select "checking/savings." Then enter your PIN and select the amount you want to withdraw.
You can also use your debit card to make payments online or by phone. To make an online payment, enter your card details on the merchant's website. To make a payment by phone, call the merchant's customer service number and provide your card details when asked.
What Protection Do Visa Debit Cards Have Against Unauthorized Charges?
If you have a Visa card, you're protected by Visa's Zero Liability policy. This policy guarantees you won't be held responsible for any unauthorized charges made with your card. That means if someone steals your card or uses it without your permission, you won't have to pay for those charges.
Visa's Zero Liability policy applies to all Visa cards, including debit and credit cards. It also applies to all transactions, including online and in-person transactions. This policy was put in place to help protect consumers against fraud and identity theft.
If you're a victim of fraud or identity theft, be sure to report it right away. You can call Visa's toll-free number 24/7 to report any incident. Visa will work with you to resolve the issue and help protect your money and identity.
What Are Virtual Debit Cards?
A virtual card is a card that isn't physical — it exists only in the digital world. Virtual cards are often used for online purchases, since they offer more security than using a regular debit card.
One of the benefits of virtual cards is that they can be used to limit how much money is spent on a purchase. For example, if you're buying something online and want to make sure you don't go over budget, you can use a virtual card instead of your regular credit or debit card. This can help you stay within budget and avoid racking up debt. Likewise, if your information is stolen during a transaction, the thief won't be able to access your other cards. This can help prevent fraud and keep your personal information safe.
If you're interested in getting a virtual card, there are a few things you should know. First, not all banks offer virtual cards, so you may need to open a new account at a bank that offers this service. Second, not all merchants accept virtual cards, so there may be some places where you can't use them. Finally, virtual cards sometimes come with associated fees, so be sure to read the terms and conditions before using one.
The Benefits of Común
When you get a checking account with Común, you'll get two debit cards: a physical one and a virtual one.
The physical card lets you make purchases at any business, and offers security thanks to its contactless capability and chip. This prevents your card details from being cloned or used for fraud.
The virtual card lets you make online purchases with more confidence, since contactless technology and chip protection aren't available on the internet — but if fraud does happen, the card can be canceled and replaced immediately. You can contact our support team anytime to report these cases.
Común debit cards work at more than 55,000 ATMs across the United States for deposits and withdrawals, and are protected by Visa's Zero Liability policy. That means any unauthorized charge won't be deducted from your checking account balance.

Certified checks are a common form of payment for thousands of immigrants living in the United States, especially for major purchases such as rent payments, buying a car, and legal settlements.
However, it is not always clear why the certification process matters and how it differs from other types of checks.
A certified check is a physical payment order that has been reviewed in advance by a financial institution to ensure there are sufficient funds in the issuer’s bank account. This is the fundamental reason it’s considered a safer form of payment than a personal check.
Below, we explain in detail what a certified check is, how it works, and why it’s important to understand the differences from other types of checks.
A certified check is a type of check with guaranteed funds, since the issuing bank has verified the money exists in the checking or personal account.
This makes it a safer form of payment than personal checks, because the bank sets aside the amount to be paid so it can be collected by the payee.
Issuing a certified check is a straightforward process you can complete directly at the financial institution of your choice.
The account holder must go to a bank and request a certified check, specifying the payee and the amount.
You must present an official ID to verify that you are the holder of the savings or checking account from which the funds will be drawn.
The bank then certifies there are sufficient funds to cover the check and freezes them to ensure the payee can cash it.
You must sign the check before finishing the process so the bank can confirm the signature matches the one on file.
Affixing the certification stamp
Finally, once the bank has verified the funds and the signature, it places a certification stamp to document completion of the process.
A cashier’s check is another way to make secure payments using a physical instrument. In this case, the bank branch issues the check after receiving the customer’s payment, so the funds come from the bank itself.
Below is a comparison between a cashier’s check and a certified check.
Cashier’s check
Certified check
Security
High; the bank verifies sufficient funds and places a hold for the payee.
Very high; the check is backed by the bank and does not depend on the issuer’s account.
Cost
At some banks they have no cost at others up to approximately $15.
Depends on the bank; typically $10–$20.
Issuance time
At the branch, after funds are verified.
Immediate.
A certified check is commonly used for significant transactions or large amounts. This gives the recipient assurance that funds are available.
When finalizing a lease or purchasing an apartment, the landlord or agent may request payment via certified check to guarantee funds.
Whether dealing directly with owners or dealerships, a certified check can be a suitable option because of the security it provides.
For example, to pay fees, settlements, or indemnities, certified checks provide security for both parties.
Some educational institutions accept certified checks as a form of payment, especially for international or first-time payments.
Do you know what to do if a check is stolen or lost? We explain it here!
While certified checks are among the safest payment methods due to the bank’s verification process, there are still fraud attempts using forged documents.
With this in mind, keep these tips in mind to avoid becoming a victim of check fraud.
Call the bank directly and provide the check number, account holder, and amount; ask them to confirm authenticity and that funds are guaranteed. Make sure you call the bank’s official number, not the one printed on the check.
A common scam is sending a check for more than the amount due and asking for the difference in cash. Confirm the check’s validity with the bank before proceeding.
Clearing can take 3–10 days. Make sure the funds have fully settled and are not just on hold.
Whenever possible, accept checks only from people you trust. If you must take a check, follow the security measures above.
In this article we explained what a certified check is, how it’s issued, how it differs from cashier’s checks, and how to use this payment method safely.
While certified checks can be a good payment option, a checking account in the U.S. is a much more secure and practical way to manage money.

Although getting a job in the United States brings a series of benefits for the quality of life of immigrants and their families, it also means committing to fulfilling the obligations required by the country's laws.
Filing a tax return is one of the processes everyone who has earned income must complete. This is done by submitting a report of annual income to the Internal Revenue Service (IRS).
Filing a tax return is particularly important for everyone, as it opens the door to access financial services such as mortgage and personal loans, which in turn help build a financial record especially for immigrants.
Filing taxes is a stressful and often confusing process for most people, especially when it involves understanding the tax institutions of another country.
Below, we show you a step-by-step guide to help you fulfill your tax obligations in the U.S. and access the benefits that come with it, such as receiving refunds and building a financial record in the country.
The first thing you should know to file your tax return in the U.S. is the documentation required by the IRS to process your information.
Make sure you have the following documents:
It is important to stay alert during tax season and prepare in advance to meet the deadlines established by law.
Follow these steps to ease the stress of tax obligations.
The first step is to gather all the necessary documents to file your annual tax return.
Once you have your documentation in order, you must decide how you will file your return: on your own or with professional help.
Keep in mind that the deadline to file your tax return is usually April 15 each year. It is essential to submit your tax return within the deadline to avoid penalties and delays in receiving your refund.
As mentioned before, there are different ways to file your tax return, which vary in cost and level of support offered. The best option depends on several factors, such as your income level and how familiar you are with tax topics.
Below is a comparative table of the different ways to file taxes in the United States.
Method
Approximate cost
Level of support
Doing it yourself with IRS-approved software
Free or up to $25
Low. Although the platform guides you step by step, you must enter all the information yourself.

Free or up to $50
Medium. You receive assistance from certified volunteers.
With private preparers or accountants
$150 to $500, depending on complexity

It depends on your situation: if you have only one source of income, you can use software, but if your income is higher or more complex, the best option is to consult a professional.

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.

Have you ever filled out a check? Although most transactions today are digital, knowing how to fill out a check is essential—especially if you are just beginning your financial life.
According to recent data, one-third of Americans paid by check in 2024, demonstrating that checks still play an important role in the U.S. economy.
You might consider checks an outdated payment method; the reality is that they are useful in specific situations. For that reason, we will explain what a check is, the different types of checks, and how to complete them properly.
Despite the digital era, checks remain a relevant traditional payment method due to their formality and traceability. They are used for rent payments, purchases, and service payments.
Additionally, checks are a common payment method among the immigrant community, who often use them while adapting to the U.S. banking system.
But what exactly is a check and what are its characteristics? It is a physical document issued by an individual or business (the drawer) to order a bank to pay a specified amount to a third party. For the payment to be processed, the drawer must have sufficient funds in their checking account.
In general, a check contains the following information:
There are different types of checks in the United States. In this case, we will focus on the personal check, although you may choose the option that best suits your needs.
A personal check is a payment order issued by an individual to another individual using the funds in a checking account.
The most common uses for personal checks include:
A certified check serves the same purpose as a personal check but is reviewed and guaranteed by the issuing bank, which verifies that the drawer has sufficient funds and holds them until the check is cashed.
A certified check provides certainty of available funds, making it a more secure method for making and receiving payments.
Unlike a personal check, a cashier’s check is issued directly by the bank, offering greater security for the payee, as the bank is responsible for issuing and safeguarding the funds.
To obtain a cashier’s check, the drawer must visit a bank branch and pay the amount to be transferred. The bank then issues the check in the name of the payee, guaranteeing that it can be cashed using the institution’s own funds and not a personal account.
It is commonly used for high-value purchases such as homes and vehicles.
While not strictly a check, it is a traditional payment method with similar functionality.
A money order is a financial instrument that allows funds to be sent via traditional mail using a certified check, which must be purchased and paid for by the drawer at an authorized location.
It allows secure money transfers without requiring a bank account.
Before issuing this type of payment order, you must know how to do it properly. Below is an example of how to fill out a check easily, starting from step one:

Remember that in the United States, the date format is mm/dd/yyyy.
Write the full name of the person to whom you are issuing the check, exactly as it appears on their official identification.
Write the numerical amount clearly.
Write the amount in words, including cents.
You may include a note specifying the reason for the payment.
Sign the check legibly in the space designated for the drawer.
Ensure that all information is accurate to avoid issues for the payee when cashing the check.
It is essential to complete checks legibly, without strike-throughs or corrections, as these may invalidate the document.
Writing amounts in words may be confusing when dealing with U.S. dollars. The following points should be kept in mind:
As you can see, knowing how to fill out a check is useful for sending and receiving money in the United States. It is a reliable and accessible alternative if you do not have a banking account.
However, issuing and cashing a check can also require significant time and effort. That’s why you can skip the trip to the bank, avoid wasting time or money on gas, and cash your check directly from your phone using Comun—no lines, no questions, no complications.
Discover Comun, the only platform designed to serve the needs of immigrant communities in the United States, with support available in Spanish.
Still have questions about how to fill out a personal check? See our FAQ section.
If there are strike-throughs or inconsistencies in the amounts, the check must be voided and a new one used.
Write the word VOID in large letters on the front of the check.
The back of the check contains the endorsement, meaning the payee’s signature for cashing the check.

Investing is one of the most powerful tools for building long-term wealth. For immigrant families in the U.S., understanding investment basics can make the difference between merely surviving and financially thriving. In this guide, we explain the fundamental concepts you need to know before you start investing.
Investing means putting money into assets with the goal of growing it over time. Unlike saving, which keeps money safe but with low returns, investing takes on some risk in exchange for the possibility of higher gains. The most common assets are stocks (ownership stakes in companies), bonds (loans to governments or companies), mutual funds (diversified portfolios), and real estate.
The higher the potential risk, the higher the return can be. Individual stocks are more volatile than government bonds. Index funds offer a balance between reduced risk through diversification and historically positive long-term returns.
Do not put all your eggs in one basket. Spreading investments across multiple assets, sectors, and geographies reduces the risk that one bad investment will ruin your entire portfolio.
Compound interest is the phenomenon of earning interest on previously earned interest. An investor who starts at age 25 will reach retirement with significantly more money than someone who starts at 35, even if they contribute the same monthly amount.
The length of time you plan to hold your investments affects which assets to choose. For goals more than 5 years away, you can take on more risk. For short-term goals, prefer more conservative options. Never invest money you need in the short term.
Yes. Most brokers in the U.S. allow non-citizens to invest, including permanent residents and people with work visas (H-1B, L-1, etc.). Some brokers also accept non-residents. To open an investment account, you generally need a tax identification number (SSN or ITIN) and a U.S. bank account.
Most modern brokers like Fidelity, Charles Schwab, and Robinhood have no minimum amount to open an account. You can buy fractional shares starting at $1. What matters is not the starting amount but consistency—investing $50-100 per month regularly produces better results than irregular large sums thanks to dollar-cost averaging (DCA).
An index fund is a fund that tracks the performance of a stock market index such as the S&P 500. Instead of selecting individual stocks, you invest in a “basket” of the 500 largest companies in the U.S. They are popular for their low cost (fees of 0.03-0.20%), automatic diversification, and historical returns that have outperformed most active managers over the long term.
You can usually keep your U.S. investment account while abroad, although some brokers restrict nonresident accounts. When you sell, you will pay capital gains taxes in the U.S. (and possibly in your country of residence). Consult a tax advisor before leaving the country to plan the transition properly.
No. A 401(k) is a tax-advantaged retirement account generally offered by your employer—the contributions reduce your taxable income now, and the money grows tax-deferred until retirement. A regular investment account (brokerage account) does not have special tax advantages but also no withdrawal restrictions. Both are complementary tools for building wealth.
The most common mistakes are: investing money you need in the short term (investments require a 3+ year horizon), selling when the market drops out of panic, not diversifying (putting everything in one company or sector), paying unnecessarily high fees, and not investing because you are “waiting for the perfect moment.” Discipline and consistency matter more than perfect market timing.

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.

International Money Transfers

As the reasons for transferring money internationally increase, so do the available methods. Whether you are sending remittances to your family, paying suppliers, or receiving payments from abroad, understanding how international transfers work will help you save time and money.
An international money transfer is the movement of funds from a bank account in one country to another account in a different country. It can be done through bank wire transfers, specialized remittance services (Western Union, Remitly, Wise), or platforms like Común that allow you to send money to Mexico directly from the app.
To choose the best service, consider: the total cost (visible fee + exchange rate margin), delivery speed, available delivery methods (bank deposit, cash pickup), and whether they accept your documentation. Use comparison tools like Monito to see real-time options for your specific corridor.
Traditional, expensive method ($25-45 per transfer), takes 1-5 business days, requires the recipient’s full bank details: account number, SWIFT/BIC, IBAN, or CLABE (Mexico).
Wise, Remitly, and Xoom offer fees lower than 3-5%, delivery from minutes to 3 days, and multiple delivery options. Wise uses the real market exchange rate. They require an SSN or ITIN in the U.S.
Común allows you to send remittances to Mexico and Latin America starting at $2.99 without requiring an SSN. Ideal for newly arrived immigrants. Options for bank deposit, cash pickup at Oxxo or Walmart.
Specialized remittance apps (Wise, Remitly, Xoom) are generally cheaper than traditional banks for international transfers. Wise is known for using the real market exchange rate with transparent fees. For specific destinations such as Mexico, platforms like Común offer transfers starting at $2.99. Use comparison tools like Monito to see the best real-time options for your specific corridor.
It depends on the method and destination country. International bank wire transfers take 1-5 business days. Remittance apps can be almost instant for cash pickup, or 1-3 business days for bank deposit. Factors such as time zones, bank cutoff times, and the destination country’s compliance requirements affect arrival time.
For an international bank wire transfer, you need: the beneficiary’s full name, the receiving bank’s name and address, the receiving bank’s SWIFT/BIC code, and the beneficiary’s account number or IBAN. For Mexico, the interbank CLABE (18 digits) is used. For remittance apps like Común, sometimes the recipient’s phone number or bank name is enough.
Yes. Limits vary by service and user verification level. Remittance apps typically allow between $2,999 and $10,000 per day for verified users. Bank wire transfers can be larger but cost more ($25-45 per transaction). Anti-money-laundering regulations require reporting transfers over $10,000 to the IRS (CTR form).
It depends on the service. Wise, Remitly, and traditional banks require an SSN or ITIN for regulatory compliance. Platforms like Común do not require an SSN — they accept a passport or consular ID — and allow you to send remittances to Mexico and Latin America starting at $2.99. This is especially useful for newly arrived immigrants who do not yet have an SSN.
Sending money abroad itself does not generate taxes in the U.S. However, if the money comes from undeclared income, that is the tax obligation to address. The IRS may require reporting foreign accounts (FBAR/FATCA) if you have more than $10,000 in foreign accounts at any point during the year.

Cashback is a rewards system that gives you back a percentage of the money you spend on eligible purchases. In simple terms, when you buy something using certain credit cards, debit cards, apps, or rewards programs, you may get a percentage of your money back on purchases, though it is usually credited to your account rather than handed over as physical cash.
If you recently moved to the United States or are learning how the financial system works, you may have heard the term 'cashback' while shopping at places like Walmart, Target, gas stations, supermarkets, or online stores.
For many people, cashback can become a practical tool to manage everyday expenses such as groceries, transportation, gas, and household purchases. While the amounts may seem small at first, they can add up over time when used consistently and responsibly.
Cashback is a type of financial reward that returns a percentage of your purchase after you spend money with a participating payment method or rewards platform.
For example:
Unlike traditional discounts, cashback usually happens after the purchase is completed. The Consumer Financial Protection Bureau (CFPB) explains that cashback rewards are commonly offered through credit cards and loyalty programs as an incentive for spending.
Cashback programs generally follow a simple process:
The reward may appear as:
Some cashback rewards appear within a few days, while others may take an entire billing cycle or longer to process. There are often minimum redemption thresholds before you can claim your cashback. Certain programs may include expiration dates. It is also important to understand that not every purchase qualifies for cashback.
While cashback and traditional discounts can both help consumers save money, they work in different ways. A traditional discount lowers the price immediately at checkout, while cashback returns part of the money after the purchase has already been completed.
| Cashback | Traditional Discount |
|---|---|
| Money is returned after the purchase | Price is reduced before purchase |
| Usually linked to cards, apps, or loyalty programs | Usually available directly in-store |
| Rewards may take days or weeks to process | Savings are immediate |
| May help track expenses digitally | Does not usually include tracking tools |
| Often limited to eligible categories or stores | Depends on store promotions |
Not all cashback programs work the same way. Before signing up for a cashback program, it is important to review details such as annual fees, interest rates, minimum redemption, expiration policies, and spending categories.
This type gives the same cashback percentage on all purchases. Example: 1.5% cashback on everything you buy. This structure is simple because you do not need to track categories or rotating offers.
Some cards or apps offer higher cashback percentages in specific categories such as supermarkets, restaurants, gas stations, or streaming subscriptions. For example: 3% on groceries, 2% on gas, 1% on all other purchases.
Some providers change cashback categories every few months. One quarter may focus on gas stations and grocery stores; another may include online shopping and travel purchases. These programs sometimes require manual activation each quarter.
Certain credit cards offer introductory cashback bonuses if you spend a minimum amount during the first months after opening the account. For example: spend $500 in the first 3 months and receive $150 cashback bonus. The Federal Trade Commission recommends reviewing terms carefully before applying for financial products with promotional offers.
Credit cards:
Many credit cards in the U.S. include cashback rewards. Some examples include products from Discover, Chase, Capital One, and American Express. Some cards focus on categories like dining or travel, while others offer flat-rate cashback.
Debit cards:
Some financial institutions offer cashback debit cards, although rewards are usually smaller than those offered by credit cards. This may appeal to people who prefer avoiding debt or credit card interest.
Cashback apps:
Several mobile apps partner with retailers and offer cashback rewards for purchases. Examples include Rakuten, Ibotta, Upside, and Honey. These apps may provide cashback for grocery shopping, online purchases, gas stations, and restaurants.
Store loyalty programs:
Retailers sometimes offer cashback or store rewards through membership programs. For example, supermarkets, pharmacies, and warehouse stores may return store credit or savings points after purchases.
Although they are often grouped together under the category of 'rewards,' each one works differently and can be useful depending on a person's spending habits, financial goals, and lifestyle.
Cashback programs generally return a percentage of the money spent on eligible purchases. Points systems usually assign a numerical value to purchases that can later be redeemed for products, gift cards, discounts, or services. Travel miles are typically associated with airlines, hotels, or travel-focused credit cards.
| Cashback | Points | Miles |
|---|---|---|
| Returns money | Rewards system value | Travel-focused rewards |
| Flexible spending | Often redeemed in specific ecosystems | Usually tied to airlines or hotels |
| Reward after spending | Redemption values vary | Best for frequent travelers |
| Common for everyday purchases | May include gift cards or products | Often used for traveling |
For many people, especially those focused on getting some value on their everyday expenses such as groceries, transportation, gas, or household purchases, cashback can feel more useful as the reward is directly connected to money rather than conversion systems or travel programs.
Focus on recurring expenses such as groceries, gas, transportation, and utility bills. This helps you avoid overspending simply to earn rewards.
A cashback offer does not automatically make a purchase worthwhile. For example, spending $200 to earn $4 cashback may not help your finances if the purchase was unnecessary.
Many apps and financial platforms allow you to monitor spending categories, cashback totals, and monthly rewards. Tracking your rewards can help you understand your spending patterns and maintain financial goals.
No. Común does not currently offer cashback programs.
However, Común provides tools and resources that offer guidance for Latin American immigrants navigating the U.S. financial system.
While cashback might be useful for some people, it is important to pay attention to commissions, as savings when commissions are included might not be as strong as initially perceived. When comparing financial tools in the United States, cashback is only one factor to consider. Fees, commissions, account accessibility, and transparency can also affect your financial experience over time.
Común's cost for opening a debit account is $0, same as the $0 minimum balance and $0 monthly commission for the debit account.
Cashback is a rewards system that returns a percentage of your purchases after you spend money using eligible cards, apps, or loyalty programs.
Cashback is usually calculated as a percentage of the purchase amount. For example, if you spend $100 and your cashback rate is 2%, you receive $2 back.
Cashback is commonly available through credit cards, debit cards, shopping apps, and retailer loyalty programs.
Cashback returns money directly, while points are part of rewards systems that may only be redeemed for specific products, gift cards, or services.
No. Común currently does not offer cashback.
In many cases, cashback earned through purchases is generally treated as a rebate rather than taxable income. However, tax treatment may vary depending on how rewards are earned. The IRS recommends consulting a tax professional for specific situations.

Online banking refers to a financial institution with a digital presence on the web, accessible from different devices. Online banking has features that set it apart from other platforms — its main characteristic is that money and account management happen entirely online. Here are the main things that set it apart from traditional banking and other platforms — keep reading!
Features of Online Banking
Now that you know what online banking is, here are the different features it offers:
Convenience: You don't need to complete part of a transaction online and finish it in person at the bank. Online banking can offer 100% online transactions, depending on the institution.
Functionality: Banking today has improved the user experience to the point that most apps are user-friendly, offering a wide range of financial products and tools so users don't have to complete some confirmations in person at the branch.
Security: This is one of the aspects online banking has focused on most, and one of the factors that limited financial products for customers in the past. Today, there's a wide range of tools that make online transactions secure, including:
Banking software: Banks have internal software that protects users — in payment methods, IP location recognition, and payment processing and authentication.
Two-factor authentication: With mobile apps, security is properly guaranteed through online banking.
Security protocols: These are the steps required to access certain financial tools. Some protocols require two-factor verification, others use randomized codes depending on the bank's criteria.
Advantages of Online Banking
Over the years, online banking has optimized its digital processes, resulting in a number of benefits for users, including:
Time savings: You don't need to go to a bank branch to complete a transaction and wait to be helped after a long wait at the branch.
Better communication: Complaints are handled promptly on many platforms. Generally, the solution is found in one of the menus within the app. This is mainly due to the standardization of solutions for the most common issues regular users face, available as options within the platform.
Streamlined processes: The ease of acquiring financial products, choosing promotional cards, making both domestic and international transactions, and checking real-time spending make online banking an ideal option.
Ease of use: The options the platform offers make navigation within the app (for smartphones) or platform extremely user-friendly.
For these reasons, it's worth understanding the different operations related to online banking, including:
Opening a bank account online.
Making transfers online.
Getting benefits through online banking.
Setting up bill pay through your bank.

In this article, we'll walk you through the advantages and requirements of having a debit account in the United States. It's worth noting that the world's financial center is New York, home to the most important payment hubs where the world's top-ranked financial institutions are connected. That's why having an account in the United States is essential if you do business globally.
Why Having a Debit Account in the United States Matters
Here are the advantages of having a debit account in the United States and what it means to have one — among the most notable benefits:
Cost: The cost to open an account in the U.S. is actually minimal, largely thanks to the digital account types available today. This gives you the ability to handle financial transactions smoothly with the people you want to do business with.
Requirements: Requirements are usually basic, as long as you're of legal age and have some form of address documentation. If you're a foreigner, it's possible to open an account in the United States without a long list of requirements or needing to be physically present.
Control: You can track fees, deductions, and payments made through the platform — for that, we recommend reading: How to Manage My Money in a Debit Account.
Ideal for Freelancers: If you do remote work, global companies typically require an account on some payment platform. For that, you'll need a U.S.-based account. That's why it's worth opening one, so you can meet the requirements of that payment platform.
Security: You get the security that comes with U.S. regulation. On top of that, funds are protected by the Federal Deposit Insurance Corporation (FDIC).
Options: There's a wide variety of ways to get a U.S. account, and among the main options is starting with a debit account, which offers alternatives for people who want an account without being a U.S. resident.
General Requirements to Open an Account in the United States
The requirements listed here are for opening a general account — keep in mind that requirements vary by account type. Among the requirements U.S. financial institutions typically ask for:
ID document: Issued by your country of residence's government (passport, national ID, or identity card depending on your country of origin).
Proof of residence: A current utility bill showing your physical address. It must include a zip code.
Email address: So the confirmation email can be sent this way if you open the account through a platform or app.
Mobile device: To authenticate transactions made through the bank's platform.
If you want to open an account in the United States, there are several options and account types available. Just choose the one that fits your needs, requirements, and that you can comfortably and securely meet the requirements for.
