How to Build Credit as a Newcomer to the US
A step-by-step guide to building your credit score from scratch when you first arrive in the United States.
Your credit score affects almost everything in America — renting an apartment, getting a phone plan, even some job applications. As a newcomer, you start with no credit history. Here's exactly how to build it from zero.
Step 1: Get a Social Security Number (SSN) or ITIN
Before you can build credit, you need an identifier. If you're authorized to work in the US, apply for an SSN at your local Social Security office. If not, apply for an Individual Taxpayer Identification Number (ITIN) through the IRS.
Step 2: Open a Bank Account
Start with a checking and savings account. This doesn't directly build credit, but banks are more likely to approve you for a credit card if you're an existing customer.
Best options for newcomers:
- Chase Total Checking (wide branch network)
- Bank of America Advantage SafePass
- Discover Online Savings (no minimum balance)
Step 3: Get a Secured Credit Card
A secured credit card requires a refundable deposit (usually $200-$500) that becomes your credit limit. Use it for small purchases and pay the full balance every month.
Recommended: Discover it Secured — no annual fee, cash back rewards, and they match your rewards in the first year.
Step 4: Use Your Card the Right Way
- Spend only 10-30% of your limit — If your limit is $500, keep your balance under $150
- Pay the full balance every month — Never just pay the minimum
- Set up autopay — Never miss a payment. Payment history is 35% of your credit score
- Don't close old cards — Length of credit history matters
Step 5: Monitor Your Credit Score
After 3-6 months, you'll have a credit score. Check it for free using:
- Discover Credit Scorecard (free for everyone, not just customers)
- Credit Karma
- Your bank's app (many banks now show your score)
Timeline: What to Expect
| Month | Milestone |
|---|---|
| 1 | Open bank account + apply for secured card |
| 3 | First credit score appears (usually 630-680) |
| 6 | Score improves to 680-720 with responsible use |
| 12 | Eligible for unsecured cards with better rewards |
| 18+ | Score can reach 750+ |
Common Mistakes to Avoid
- Applying for too many cards at once — Each application is a hard inquiry that temporarily lowers your score
- Carrying a balance — Interest rates on credit cards are 20-30%. Always pay in full
- Missing payments — One missed payment can drop your score by 100+ points
- Ignoring your credit report — Check for errors at annualcreditreport.com once a year
The Bottom Line
Building credit in the US is a marathon, not a sprint. But if you start on day one with a secured card and follow these steps, you'll have a solid credit score within a year. That score is your financial passport in America.
