Staying at SFO

Who can leave SFO without a visa?

The United States has no airside (sterile) international transit: the Transit Without Visa provisions in 8 CFR 212.1(f) are 'Reserved', and CBP processing must be completed at the first US airport, so every connecting passenger is inspected by CBP and formally enters the US. Visa Waiver Program nationals therefore need an approved ESTA even for a same-airport connection; everyone else (except Canadians) needs a visa (C-1 transit or B-1/B-2). Checked bags are normally reclaimed, cleared through customs and re-dropped before the connecting flight. Once admitted, a passenger can leave the airport during the layover on the same ESTA/visa.

Good to know: No airside transit in the US: international arrivals clear CBP, collect and recheck bags, then re-clear TSA. BART station is in the International Terminal (Level 3); from Terminals 1-3 take the free AirTrain (24h) to the International Terminal or Garage G/BART stop. BART does not run overnight and has a late start on weekends (BART guide: roughly from 05:00 weekdays, 06:30 Sat, 08:00 Sun; last trains around midnight), so check for early/late layovers.
