Most Korean students and new immigrants assume you need an SSN to get any US credit card. You don’t. You can get a credit card without an SSN, because several major issuers accept ITIN or even just a passport. The gap between what people believe and what issuers actually allow costs immigrants real money. Every month you delay is a month your US credit history sits at zero, and that means higher interest rates on future car loans, a harder time qualifying for an apartment, and a longer road to your first mortgage.
This post maps out exactly which cards are available and what each issuer requires. It also covers how to build a credit profile from day one, whether you have an SSN, an ITIN, or neither. If you just landed, pair it with our first-week US banking setup checklist.
Quick Summary
- Discover it Student cards and OpenSky Secured Visa accept ITIN applicants, so you can start a credit card without an SSN.
- A secured card with a $200–$500 deposit is often the fastest path to a first US credit line.
- Starting 1–2 years before you get your SSN means you can qualify for premium cards much sooner.
Why Starting Early Changes Everything
US credit bureaus — Equifax, Experian, TransUnion — have no record of your Korean credit history. The moment you arrive, your credit file is blank. That blank file affects more than credit cards. Landlords run credit checks, car dealerships price loans based on your score, and some employers check credit reports for certain roles.
The average time to build a FICO score from zero to 700+ is about 12–18 months, assuming you use credit responsibly. Wait until you have your SSN before applying for your first card, and you’re pushing that 700+ mark 1–2 years further into the future. For someone on an F1 visa who plans to stay in the US, that delay has compounding effects.
The good news: several issuers will let you start building that history today.
Actionable takeaway: Apply for at least one card within your first 90 days in the US, even if it’s a secured card. The date your account opens is when your credit history clock starts.
Credit Cards Without an SSN: Issuers That Accept ITIN
These cards explicitly allow ITIN in place of SSN, or have a documented history of approvals for ITIN holders.
Discover it Student Chrome / Discover it Student Cash Back
Discover is the most consistently ITIN-friendly major issuer for students. Both student cards accept ITIN as a substitute for SSN on the application. There is no annual fee. The Cash Back variant offers 5% rotating quarterly categories (gas stations, restaurants, Amazon, etc.); the Chrome variant gives 2% back at gas stations and restaurants up to $1,000 per quarter, 1% everywhere else. Discover also matches all cash back earned in your first year. That’s a meaningful benefit for someone building credit with moderate spend.
To apply, go to Discover’s student card page and select “ITIN” when the application asks for your social security or taxpayer ID number. You will need a US address and a bank account.
Citi Custom Cash / Citi Double Cash
Citi has a history of approving ITIN applicants for several of its consumer cards, though this is not stated in official policy documents. Two are worth trying: the Citi Double Cash (2% back on everything — 1% when you buy, 1% when you pay), and the Citi Custom Cash (5% back in your top eligible spend category up to $500 per month). Approval is not guaranteed and underwriting decisions can vary by branch and by year. Still, ITIN applicants have documented approvals on both cards.
Apply online. If denied, calling the reconsideration line with documentation of steady income or a US bank account sometimes reverses the decision.
OpenSky Secured Visa Credit Card
OpenSky requires no credit check at all and does not require an SSN. You fund a security deposit (minimum $200, up to $3,000), and that deposit becomes your credit limit. OpenSky reports to all three major bureaus monthly, which means every on-time payment builds your history. There is a $35 annual fee, which is the main downside. This card is not glamorous. It is, however, one of the most reliable paths to a first US credit line for anyone who cannot qualify for unsecured products yet.
Actionable takeaway: Have an ITIN? Try Discover it Student first — it’s the best confirmed path to a credit card without an SSN. Don’t have one yet? OpenSky is your most reliable starting point.
Credit-Builder Cards and Programs That Work Without an SSN
Self Credit Builder Account
Self is not a credit card. It is a credit-builder loan structured so that your monthly payments are reported to all three bureaus. You pay $25–$150 per month into a locked savings account. At the end of the loan term (12 or 24 months), you receive the money back minus fees. Self does not require an SSN; an ITIN works. At the end of the term, Self offers a secured credit card using your accumulated savings as the deposit.
This path is slower than a traditional credit card. It still works well for people who want to build both savings and credit at the same time.
Community Bank and Credit Union Programs
Several banks with strong ties to specific immigrant communities in the US offer credit cards to international students or new immigrants, with no SSN required:
- Hanmi Bank (Korean community focus, branches in California, New York, New Jersey, Texas, Illinois, Georgia, Virginia) offers personal credit products to non-SSN applicants and has Korean-speaking staff.
- MUFG Bank serves the Japanese-American community with similar flexibility.
- Local credit unions near universities sometimes offer secured cards or starter accounts designed for F1 holders. Check your university’s international student office — many have partnerships.
These options are geographically limited but worth checking if you are near a branch.
Actionable takeaway: Want to build credit and savings at the same time? Self is a reasonable complement to a secured card. Do not use it as a substitute, though — having an actual revolving credit line on your report builds score faster.
After You Get Your SSN: The Upgrade Path
Once you have an SSN — whether through OPT, a work visa, or any other path — you gain access to the full range of US credit products. Have you already been building credit for 12–24 months? You’re in a much stronger position than someone starting from zero.
The first two cards to apply for after getting your SSN:
Chase Freedom Unlimited — 1.5% back on all purchases, 3% on dining and drugstores, no annual fee. Chase is one of the stricter issuers. Their informal “5/24 rule” limits approvals if you have opened 5+ cards in the past 24 months, so applying early while your application count is low makes sense.
Discover it (non-student version) — Started with the student card? Call Discover to upgrade your existing account to the standard version. This keeps your account age intact, which helps your score.
Within 6–12 months of getting your SSN, aim to have 2–3 cards with a total credit limit above $5,000. Keep your utilization rate below 30%.
Actionable takeaway: Apply for Chase Freedom Unlimited within the first 3–6 months of receiving your SSN. The earlier you get into the Chase ecosystem, the better positioned you are for premium travel cards later.
What to Avoid
Secured cards with high fees: Some secured card issuers charge $75–$99 annual fees plus processing fees. The OpenSky $35 annual fee is acceptable. Avoid anything above $50 annually for a secured product — the credit-building benefit is the same regardless of fee.
Store-only cards: Retail store cards (Target RedCard, Amazon Store Card) can be useful eventually. They report as closed-loop credit lines, though, which are weaker for score-building than general-purpose Visa or Mastercard products. Do not use a store card as your only credit account.
Payday loan products: These do not build credit history and charge extremely high effective interest rates. Avoid entirely.
Carrying a balance: The single most damaging myth about credit cards is that carrying a balance helps your score. It does not. Pay the statement balance in full every month. Carrying a balance costs you interest and does nothing for your FICO score.
Actionable takeaway: Your first card should be a Visa or Mastercard, not a store card. It should report to all three bureaus and have an annual fee below $50 if secured.
FAQ
Can I apply for a credit card without an SSN the day I arrive in the US?
Yes, if you have a US address and a bank account. OpenSky does not require a credit history or SSN check. Discover it Student requires an ITIN. You must apply for that through the IRS separately if you do not have one.
Will applying for a credit card hurt my credit score if I have no US credit history?
A hard inquiry adds a small negative mark (typically 5–10 points) to your credit file. Since you are starting from zero, the first inquiry has minimal practical impact. The account you open will add positive history that far outweighs the inquiry within 3–6 months.
How long does it take to get an ITIN?
ITIN processing takes approximately 7–11 weeks when submitted by mail. It’s faster if you use an IRS Certifying Acceptance Agent (CAA); many Korean CPAs in major cities are IRS-certified CAAs. Planning to get a credit card without an SSN using an ITIN? Start the application process as early as possible. And if you’re married, an ITIN for your spouse can also unlock thousands in tax savings from filing jointly.
If I leave the US, what happens to my credit history?
Your US credit file remains active indefinitely even if you leave the country. If you return to the US, your history picks up where it left off. Keep at least one account open to prevent it from being closed due to inactivity — even one small recurring charge on it is enough.
Disclaimer: Credit card approval decisions are made by individual issuers and can change without notice. ITIN acceptance policies are not always published officially and may vary by application method, applicant profile, and issuer policy updates. Verify current requirements directly with the issuer before applying. This post reflects information available as of mid-2026 and is for educational purposes only.
