📌 Real Case Study
María T., 32 — Colombia → Chicago, 2022
María arrived in January 2022 with her passport, a Colombian bank account, and zero U.S. credit history. She walked into a Chase branch and asked to open a credit card. The teller said no — without a Social Security Number, she couldn’t proceed. She tried Bank of America. Same answer. Then a credit union. Same. On her fourth attempt, she found a Capital One branch manager who knew the ITIN rule: any legal resident with a valid ITIN can apply for a secured credit card. Eleven weeks after filing her ITIN application, her card arrived. Seventeen months later, her credit score hit 714 — and Capital One upgraded her to an unsecured card with a $3,200 limit, no deposit required.

“I was told ‘no’ three times by bank tellers who simply didn’t know the rules. The ITIN is a perfectly valid tax ID for opening credit. The problem wasn’t the law — it was the bank employees who didn’t know it.”

Frequently Asked Questions
Do I need an SSN to get a credit card in the U.S.?
No. Many issuers — including Discover, Capital One, and Bank of America — accept an ITIN (Individual Taxpayer Identification Number) in place of an SSN. Some banks also accept foreign passports for initial account opening.
How do I apply for an ITIN?
Submit IRS Form W-7 along with proof of foreign status and a valid foreign passport (or other IRS-accepted documents). Processing takes 7–11 weeks. You can also apply through an IRS Certified Acceptance Agent (CAA), which is often faster.
Can I build credit in the U.S. with an ITIN?
Yes. Credit cards, credit builder loans, and secured cards are all available with an ITIN. Your credit score is built from U.S.-reported account activity, not from your immigration status.
How long does it take to get an ITIN?
Standard processing by mail takes 7–11 weeks. Applying through a Certified Acceptance Agent (CAA) or at an IRS Taxpayer Assistance Center in person can be faster. ITIN applications are only processed during filing season (January–August).
What’s the difference between an SSN and an ITIN for banking?
An SSN grants full banking and credit access. An ITIN is a tax-processing number that many — but not all — banks and credit issuers accept. You cannot use an ITIN for employment purposes. For banking, the practical difference is smaller than most people think.
Frequently Asked Questions: SSN and ITIN for Immigrants
Can I apply for an ITIN if I have work authorization? Generally no — if you’re authorized to work in the U.S. (H-1B, L-1, green card, work permit), you must apply for an SSN, not an ITIN. The IRS requires you to use an SSN if you’re eligible for one.
How long does it take to get an ITIN? The IRS processes ITIN applications in approximately 6–8 weeks outside of tax season. During January–April, processing can take 10–12 weeks. Applications submitted with a tax return are processed when the return is processed.
Does having an ITIN affect my immigration status? No. The IRS has a strict privacy policy and does not share ITIN information with immigration enforcement agencies. The IRS’s published policy states that ITIN data is confidential under Section 6103 of the Internal Revenue Code.
Can I use my ITIN to open a bank account? Yes, at most major banks including Wells Fargo, Bank of America, and Capital One. Present your ITIN along with a passport or national ID. Online banks like Ally or Marcus typically require an SSN.
What happens if I get an SSN after having an ITIN? You must notify the IRS by sending a letter with both numbers to the IRS ITIN Unit. The IRS assigns all prior tax filings under your ITIN to your SSN record. Do not file two separate tax returns — there is a formal process to merge the records.
Can I claim the Earned Income Tax Credit with an ITIN? No. The EITC specifically requires an SSN. This is one reason it’s important to get an SSN as soon as you have work authorization — the EITC can be worth up to $7,430 per year for qualifying families.

Frequently Asked Questions
Can I get a credit card with only an ITIN and no SSN?
Yes. Several major banks and credit card issuers accept an ITIN instead of an SSN for credit card applications, including Capital One, Bank of America, and some credit unions. You will typically need to start with a secured credit card.
What is the difference between an SSN and an ITIN?
An SSN (Social Security Number) is issued to U.S. citizens and authorized workers. An ITIN (Individual Taxpayer Identification Number) is issued by the IRS to individuals who need to file U.S. taxes but are not eligible for an SSN. An ITIN does not authorize work or provide Social Security benefits.
How long does it take to get an ITIN?
ITIN processing takes 7-11 weeks during peak tax season (January to April) and 4-6 weeks at other times. Using a Certified Acceptance Agent can speed up the process and avoids mailing your original passport.
