Banking & Credit Score in the USA
In the United States, your credit history is no minor detail: it shapes the lease you can sign, the rate on your car loan, your eligibility for a mortgage, sometimes even your insurance premium and certain jobs. For a newcomer, that history starts literally at zero on arrival. This page explains how to open an account, get a credit card, and build a credit score quickly and cleanly.
This page provides general information only and does not constitute financial advice. Account-opening requirements, limits and fees vary by bank and by immigration status. Check the banks' official pages and consult a licensed adviser for your situation.
SSN, ITIN, and Bank Accounts
The Social Security Number (SSN) is a nine-digit identifier issued by the Social Security Administration. It is required to work in the US and for most financial products. If your status does not entitle you to one (visitors, some spouses), you can request an Individual Taxpayer Identification Number (ITIN) from the IRS, which serves tax purposes.
To open a checking or savings account, most banks ask for:
- A tax identifier: SSN or ITIN.
- A photo ID: passport or a state driver's license.
- Proof of a US address: a lease, a utility bill, or official mail.
- An initial deposit, sometimes nominal ($5 to $100).
A few large banks (Chase, Bank of America, Wells Fargo, Citi) have the advantage of physical ubiquity. Neobanks and online banks (Charles Schwab, Capital One 360, Ally, Discover) often offer lower fees and better online service, but can be more demanding on documentation for non-citizens.
Checking, Savings, Debit, Credit
Four distinct things that are best not confused:
- Checking account: for receiving your salary and paying bills.
- Savings account: earns interest at a variable rate. Online banks generally pay far more than brick-and-mortar branches.
- Debit card: a payment card linked to your checking account. The debit is immediate. It does not build a credit score.
- Credit card: you pay later, up to a granted limit. Used well, it is the primary tool for building credit history.
Understanding the Credit Score
Three private bureaus — Equifax, Experian, TransUnion — collect information on your credit behavior. From that data, two scoring models dominate: FICO Score (the most used by lenders) and VantageScore. Both produce a number between 300 and 850. A score considered "good" is above 670, "very good" above 740, and "excellent" above 800. Below 580, a profile is judged risky and credit becomes expensive.
The FICO Score depends on five major categories, whose approximate weightings are published by FICO:
- Payment history (~35%): paying on time is by far the most important factor.
- Credit utilization (~30%): how much you use relative to your limits. Aim for under 30%, ideally under 10%.
- Length of history (~15%): the longer the history, the better. Avoid closing an old card without reason.
- Credit mix (~10%): having several types of credit (card, student loan, auto loan) helps at the margin.
- Recent inquiries (~10%): too many new applications in a short period hurts the score.
The "Zero History" Strategy: How to Start
Without a US history, many banks will refuse a standard credit card at first. Several levers exist:
- Secured credit card: you place a deposit ($200, $500, etc.) that becomes your limit. After 6 to 12 months of good behavior, the bank generally returns the deposit and converts you to an unsecured card.
- Newcomer programs offered by some international banks (HSBC, Citi, etc.) that accept a foreign history to open a "starter" card.
- Becoming an authorized user on the card of someone close to you with a good score. This adds their history to yours, provided the issuer reports it to the bureaus.
- A student loan or auto loan with a co-signer, if you need one anyway.
Quick Decision: Which Card Should You Apply For?
The main criteria for comparing a credit card:
- Annual fee: zero for most entry-level cards, several hundred dollars for premium cards that pay it back in travel perks.
- APR (annual interest rate on the unpaid balance): high, often above 20%. If you pay the balance in full each month, the APR never applies.
- Foreign transaction fee: 0% to 3%. Important if you travel or buy abroad.
- Cashback or points: a flat 1.5% cashback is a common baseline; some specialized cards pay more by category.
- Welcome bonus conditioned on an amount spent within 3 months.
Common Mistakes to Avoid
- Not paying the statement balance in full each month and paying 20% interest on the carried balance.
- Pushing utilization above 50% of your limit even if you pay it off later: it is the snapshot that is reported to the bureaus.
- Closing your first card as soon as you get a better one: this shortens the average age of your history.
- Stacking up hard inquiries within a few weeks (each application costs a few points).
- Ignoring autopay setups — an accidental late payment weighs on the score for a long time.
- Confusing debit and credit: a debit card does not build a score.
Monitoring and Fixing Your Reports
In the US, you have the right to access your credit report for free from all three bureaus via the official site AnnualCreditReport.com. Many banks also offer free FICO Score tracking. If you spot an error (an account that is not yours, a wrong balance), you can dispute it for free with the bureau concerned.
Key Takeaways
- Without an SSN or ITIN, access to banking services is very limited. Apply for the SSN as soon as possible.
- A credit score is built over time: start early, even with a small secured card.
- Paying the balance in full each month and using under 30% of your limit is already enough to build a good score.
- Do not close your first cards without reason: age matters.
- Monitor your reports regularly and dispute errors without hesitation.

Frequently Asked Questions
Can I open a bank account without an SSN?
It is possible at some banks using an ITIN and a passport, but options are more limited and a few products may be off the table. The simplest path is to apply for an SSN as soon as your status allows it.
How long does it take to build a usable credit score?
Most people see a score appear after about three to six months of activity on a credit account that reports to the bureaus. Reaching a "good" score (670+) typically takes a year or more of consistent, on-time payments and low utilization.
Does using a debit card help my credit?
No. A debit card draws directly from your checking account and is not reported to the credit bureaus. Only credit products (credit cards, loans) build a credit history.
Is my money safe in a US bank?
Deposits at banks covered by the FDIC are insured up to $250,000 per depositor, per bank, per ownership category. Credit unions have equivalent coverage through the NCUA.
Why does my credit score matter for renting an apartment?
Landlords routinely run a credit check to gauge whether you reliably pay bills. A thin or low score can mean a denied application, a larger deposit, or the need for a co-signer. This is also why your auto insurance premiums may be higher at first.
