US citizens need an Electronic Travel Authorisation (ETA) to visit the UK for tourism, business, or transit. It's a quick online application, not a traditional visa, and you'll need it before you board your flight. The ETA is valid for multiple entries over two years, but you can stay for a maximum of 6 months per visit.
Apply for United Kingdom eVisaRequired for most visa-exempt visitors since 2024-2025. Not a visa — approval is linked electronically to your passport. Apply before you travel.
Entry requirements
| Requirement | Details | Status |
|---|---|---|
| UK Electronic Travel Authorisation (ETA) or Standard Visitor VisaYou must get this online approval before flying to the UK. For US citizens visiting for tourism, business, or study up to 6 months | US citizens do not need a traditional visa for short visits, but from 2026, an Electronic Travel Authorisation (ETA) is required before travel. Apply online via the official UK government website at least 3 days before departure. The ETA costs £10 and is valid for 2 years or until the passport expires. | Required |
| Passport validityCheck your passport expiry date now – if it's close, renew before booking. Must be valid for at least 6 months from your date of arrival | Your US passport must be valid for at least 6 months beyond your intended date of departure from the UK. If your passport expires sooner, renew it before applying for the ETA. | Required |
| Blank passport pagesMake sure there's a completely blank page – not just a margin. At least 1 blank page for entry stamp | Your passport must have at least 1 blank page (not counting the endorsement pages) for the UK Border Force to stamp on arrival. | Required |
| Return or onward ticketBorder officers may ask to see your travel plans – have them handy. Proof of departure from the UK | You must be able to show evidence of a return or onward ticket to leave the UK before your 6-month visit ends. This can be a flight, train, or ferry booking. | Required |
| Proof of fundsNot always asked, but be ready to show you can support yourself. Sufficient money for your stay | You should be able to demonstrate that you have enough money to cover your accommodation, living expenses, and return travel without working in the UK. Bank statements or credit cards are acceptable. | Recommended |
| Accommodation detailsBorder officers may ask where you're staying – have the details written down. Where you'll be staying | Have the address and contact details of your hotel, host, or rental property ready. If staying with friends or family, carry their address and phone number. | Recommended |
| Travel insuranceProtect yourself from high medical costs – insurance is cheap peace of mind. Medical and trip coverage | Although not mandatory, comprehensive travel insurance covering medical treatment and repatriation is strongly advised. The UK's National Health Service is not free for visitors. | Recommended |
| Arrival declarationYou don't need to fill out any arrival form – just have your passport ready. UK landing card | No arrival declaration or landing card is required for US citizens entering the UK. You will go through ePassport gates if eligible, or see a Border Force officer. | Not required |
ETA is not a visa
The UK ETA is an electronic travel authorisation, not a visa. You don't need to visit an embassy or provide biometrics. It's a simple online form that takes about 10 minutes.
Passport validity is critical
Your passport must be valid for at least 6 months from your arrival date. Airlines check this before you board, and if it's not valid, you'll be refused boarding — no exceptions.
ePassport gates are fast
If you're 18 or older, use the ePassport gates at Heathrow, Gatwick, Manchester, and other major airports. You'll be through in under a minute, no questions asked.
What happens at the border
1
Apply for your ETA online
Go to the official UK government ETA website and fill out the application. You'll need your passport details, a valid email, and a debit/credit card to pay the £10 fee. Approval usually comes within minutes, but allow up to 3 working days.
2
Check your email for approval
Once approved, you'll receive an email with your ETA reference number. It's automatically linked to your passport, so you don't need to print anything. Double-check the name and passport number match exactly.
3
Arrive at the UK border
At airports like Heathrow, Gatwick, or Manchester, head to the ePassport gates if you're over 18 and have a biometric passport. Scan your passport and look into the camera — no stamp needed. If you're not eligible or the gate fails, join the standard queue for a Border Force officer.
4
Answer questions if asked
If you're in the standard queue, the officer may ask about your trip, where you're staying, and how long you plan to stay. Answer clearly and honestly. Have your return ticket and accommodation details ready.

Frequently asked questions
No, you don't need a traditional visa. You need an Electronic Travel Authorisation (ETA), which is a digital permission to travel. It's quick to apply for online and costs £10.
You can stay for up to 6 months per visit. The ETA itself is valid for 2 years or until your passport expires, whichever comes first, and allows multiple entries.
Most applications are approved within minutes, but the official guidance says to allow up to 3 working days. Apply well in advance to avoid last-minute stress.
If your ETA is denied, you'll receive an email explaining why. You can reapply if the issue is fixable (like a typo), or you may need to apply for a standard visitor visa instead. Contact UK Visas and Immigration for guidance.
Yes, if you're a US citizen aged 18 or over with a biometric passport, you can use the ePassport gates at most major airports. This means you won't need to speak to an officer and won't get a stamp.
No, the ETA covers the entire United Kingdom, including England, Scotland, Wales, and Northern Ireland.
Your ETA is linked to your passport number. If you get a new passport, you'll need to apply for a new ETA. The old one won't transfer.
