Short answer
Your foreign credit history doesn't transfer, so you start with no US score. The fastest honest path is a secured card or a newcomer card: make small purchases, pay the balance in full every month, and make sure it reports to all three bureaus. Pay on time, keep utilization under 30% (ideally under 10%), and most people reach 700+ within about a year.
You start blank, not bad
A US credit score (FICO, 300–850) decides whether you can rent, get a card, or finance a car, and what rate you pay. When you arrive you have no file, which reads as "no score" — not a low one. That's good news: there's nothing negative to undo, just history to build.
Get your first card
Three honest on-ramps, fastest first:
- Secured card — you put down a refundable deposit (say $300) that becomes your limit. Easiest to get with no history. After 6–12 months of on-time use, many convert to a normal card and return your deposit.
- Newcomer cards — some issuers approve you using your foreign credit history (e.g. via Amex Global Transfer or Nova Credit-powered products) if you banked with a partner abroad.
- Authorized user — if a trusted friend/partner with good US credit adds you to their card, their history can help yours.
The two habits that matter most
You don't need to be clever — you need to be boring and consistent:
- Pay every bill on time. Payment history is the single biggest factor. One missed payment hurts more than months of good behavior help.
- Keep utilization low. Stay under 30% of your limit, ideally under 10%. On a $300 secured card, that means keeping the balance under ~$30–90 and paying it off.
What actually builds a FICO score
| Factor | Weight | What to do |
|---|---|---|
| Payment history | 35% | Never miss — set autopay for the full balance. |
| Amounts owed (utilization) | 30% | Keep balances well under the limit. |
| Length of history | 15% | Keep your first card open forever. |
| Credit mix | 10% | Comes naturally over time. |
| New credit | 10% | Don't apply for many cards at once. |
Timeline to 700+
You'll generate a score after about 6 months of activity. With on-time payments and low utilization, most new arrivals clear 700+ within a year — enough to rent comfortably and qualify for normal cards and loans.
Mistakes that quietly set you back
- Closing your first card — it shortens your history. Keep it open.
- Carrying a balance "to build credit" — a myth. Pay in full; you still build history and pay no interest.
- Applying for several cards quickly — each pull dings you and lowers average age.
- Letting one payment slip — autopay the full statement balance so it can't happen.
Frequently asked
Does my home-country credit history transfer to the US?
No, US bureaus don't see your foreign history. However, a few newcomer card products (e.g. via Nova Credit or Amex Global Transfer) can use it to approve your first US card.
How long does it take to build US credit?
You'll usually have a score after about 6 months of activity, and with good habits most people reach 700+ within a year.
Do I need to carry a balance to build credit?
No — this is a common myth. Paying your statement balance in full every month still builds history and saves you interest.
Can I get a credit card without an SSN?
Some newcomer cards accept an ITIN or foreign history, but most US cards require an SSN. Open a bank account first, then apply once your SSN arrives.
