US credit bureaus (Equifax, Experian, TransUnion) do not import or recognize foreign credit histories

A person who has spent 15 years building a perfect credit history in the UK, Germany, India, or Japan arrives in the US and discovers their credit score is not zero — it simply does not exist. The three US credit bureaus have no mechanism to ingest, translate, or recognize credit data from foreign bureaus. So what? Without a credit score, the person is classified as a 'thin file' or 'no file' consumer, which means automated underwriting systems at every major lender immediately reject their applications. So what? Being auto-rejected means they cannot get an unsecured credit card, a car loan, or a personal loan through normal channels, even if they have a high-paying job and substantial savings. So what? Without access to credit products, they cannot begin building a US credit history, creating a circular trap: you need credit history to get credit, but you need credit to build credit history. So what? This circular trap forces them into predatory products like secured credit cards with high fees, subprime auto loans at 15-20% APR, or rent-to-own arrangements that cost far more than market rate. So what? Over the first 2-3 years in the US, a financially responsible immigrant can lose tens of thousands of dollars in unnecessary interest and fees compared to a US-born peer with identical income, simply because the credit system treats them as if they have never managed money before. This persists structurally because the three US credit bureaus are private companies with no regulatory obligation to accept foreign data, the data formats and legal frameworks differ across countries (making integration genuinely complex), and lenders have no financial incentive to build custom underwriting models for a relatively small immigrant population when automated FICO-based decisioning is cheaper.
