Ah, our tea-drinking friends from across the pond. You’re in the Visa Waiver Program, so you’re safe for 90 days. But here’s the twist: British passport holders need ESTA too. I know, I know—you beat us in 1776. But do not ever mention that at immigration. They will not be amused.
Also, if you’re British and you’ve visited Iran, Iraq, Syria, or a few other countries recently? Your ESTA will be denied. You’ll need to apply for a full visa. Yeah, it’s a pain. But rules are rules.
What if you’re just transiting through New York?
Good question. Say you’re flying from London to Mexico City, but you change planes at JFK. Do you need a visa? Yes, if you’re from a country not in the waiver program. The US doesn’t have a magical “I’m just passing through” pass. You clear US customs even for a layover. So plan ahead, or you’ll be sleeping on an airport bench.
One exception: If you’re on an airside transit and your flight is direct to Canada? Sometimes the rules relax. But don’t bet your vacation on “sometimes.” Check with the airline.
