US credit history does not travel with your passport. A clean record in London or Toronto usually will not appear when a Brooklyn landlord or an AT&T store runs a US soft or hard pull. You build a new file from US revolving and installment accounts that report to the three nationwide consumer reporting agencies: Experian, Equifax, and TransUnion. Until that file exists, many apartments, postpaid phones, and car loans ask for larger deposits or a US cosigner.
How do you open the first accounts that report?
Start with a US bank account and a Social Security number (SSN) when you are eligible. Some products accept an Individual Taxpayer Identification Number (ITIN), but SSN-linked products are more common for mainstream cards. See Open bank account and Get ssn.
A secured credit card is the classic newcomer tool. You place a cash deposit with the issuer. That deposit usually becomes your credit limit. Use a small share of the limit and pay the statement balance in full by the due date. Confirm the card reports to all three bureaus. A card that reports to only one bureau helps less when a landlord pulls a different one.
Becoming an authorized user on a spouse's or parent's long-standing US card can add history faster if the issuer reports authorized-user activity. You are not the primary borrower, so this path depends on someone else's clean account. It is not available to every arrival.
Credit-builder loans from some credit unions also report monthly payments. Read fees before you treat them as mandatory.
How do scores and rent reporting fit in?
A FICO score is a brand of credit score model many US lenders use. Other scoring models exist. Scores need a file with enough reportable history. No US accounts usually means no meaningful US score, not a score of zero that still works like a foreign rating.
The Consumer Financial Protection Bureau (CFPB) points consumers to AnnualCreditReport.com for free weekly access to Experian, Equifax, and TransUnion reports under federal rules. Pull the reports after a few months of on-time payments to confirm the secured card appears and that personal data is correct.
Rent reporting services can add on-time rent to some bureau files, but they are optional, sometimes paid, and not universally used by every landlord's screening vendor. Treat rent reporting as a possible boost after you already have a primary revolving account, not as a substitute for a card that reports widely. Utility and phone payments likewise do not always appear on traditional FICO models unless a specific reporting product adds them.
Why movers feel the credit gap first
In expensive metros such as New York City, San Francisco, and Seattle, rental applications often include a credit check beside income proof. Postpaid mobile plans and auto financing follow the same pattern. Building even a thin positive file before you shop for a car or a market-rate lease reduces deposit stacking. Pair this process with realistic budgets in How expensive is.
Avoid many hard credit inquiries in the same week while you are still thin-filed. Shop rates inside a short window when you truly need a loan.
Common misconceptions
Paying cash for everything in the United States does not build bureau history. On-time rent paid outside a reporting channel often stays invisible to Experian, Equifax, and TransUnion.
A high foreign credit score also does not automatically transfer. You still need US-reported accounts unless a niche cross-border product explicitly builds a US file.
Summary
Build US credit by opening reportable accounts, especially a secured card that reports to Experian, Equifax, and TransUnion, and by paying on time every month. Add authorized-user status only when a trusted person with a strong US card can help.
Check free CFPB-authorized reports to confirm the file is forming, and expect landlords and phone carriers to care about that US history long before they care about your credit record abroad.
