United Kingdom entry requirements for United States passport holders
US citizens do not need a visa for tourist or business visits to the UK for up to 6 months. You'll typically need a valid passport and no prior immigration issues to enter through the automated e-gates at most airports.
Entry requirements
| Requirement | Details | Status |
|---|---|---|
| ETA application Electronic Travel Authorisation (ETA) | Since January 8, 2025, US citizens need an ETA before flying to the UK. Apply at gov.uk/apply-uk-visa — it costs £10, takes about 10 minutes, and is valid for multiple trips over 2 years. Approval usually comes within minutes, but apply at least 48 hours before departure.Apply for ETA | Required |
| Valid passport Must be valid for entire stay | Your US passport only needs to be valid for the duration of your stay in the UK — no 6-month rule. Airlines may still check for at least 6 months validity, so if your passport expires within 6 months, bring a second form of ID or renew before travel. | Required |
| Return or onward ticket Proof of onward travel | Immigration officers at UK borders routinely ask for proof of onward travel — a return flight, onward ticket, or itinerary showing you leave within your visa-free stay. Have a printed or digital copy ready. | Required |
| Proof of accommodation Hotel booking or host invitation | Carry a hotel confirmation, Airbnb booking, or a letter from your host with their address and contact details. Officers rarely ask for it, but if they do, you need a clear answer on where you're staying each night. | Recommended |
| Proof of funds Bank statements or cash | Have access to at least £50–£100 per day of your stay — a bank statement, credit card, or cash works. Officers almost never check this for US citizens, but it's smart to have a recent statement on your phone. | Recommended |
