How long does it take to build credit in the USA?
Short answer
About six months of activity on at least one account before a FICO score exists at all. A year of on-time payments with low utilization typically reaches the high 600s; 740-plus — where the best loan pricing starts — generally takes two to three years. Foreign credit history transfers nothing.

FICO requires roughly six months of reported history and at least one account updated in the last six months before it will generate a score. Until then you are 'credit invisible' — worse for approvals than a low score, because there is nothing to evaluate.
The two levers that matter most: payment history (35 percent of the score — one 30-day late mark stays for seven years) and utilization (30 percent — the share of card limits in use, ideally under 10 percent). Utilization is a statement-date snapshot, so paying the balance down before the statement closes, not just by the due date, is what produces a low reported figure.
The fast starts: a secured card with a $200–500 deposit reporting to all three bureaus, or being added as an authorized user on a family member's old, clean account — which can import that account's history to your file if the issuer reports authorized users.
Time itself is a factor you cannot rush: average account age counts for 15 percent, which is why closing your oldest card hurts and why the score keeps drifting upward for years after your habits are already perfect.
Rent-reporting services can add on-time rent to your file, and some newcomer-focused issuers consider foreign credit data for a first card — but the US file itself always starts at zero.

Score mechanics come from the CFPB and FTC as cited; the six-month generation rule is FICO's published model requirement. The timeline estimates for reaching specific bands are our synthesis of how the factors compound — individual results vary with limits, mix and starting point.
