Do you need a transit visa for United States?
The US has no international transit zone — every traveler clears immigration, so a transit (C-1) visa or ESTA/visa is required.
Staying airside (not leaving the airport)
Not available. The United States has no sterile international transit area: every passenger connecting through a US airport must clear US immigration and customs, even to change planes.
Leaving the airport during your layover
Same as airside — you have already entered the inspection process, so you need the same authorization as a visitor.
Key transit schemes & facts
- Because there is no airside transit, you need either an ESTA (if you're from a Visa Waiver Program country), a B-1/B-2 visitor visa, or a dedicated C-1 transit visa.
- A C-1 transit visa is for travelers passing through the US to another country.
- Allow extra connection time — you must collect and re-check baggage and pass security again.
