ETA (United Kingdom Electronic Travel Authorization)--Complete one month prior to travel
Details
U.S. travelers visiting the U.K. for short stays in 2026 and beyond will need a new Electronic Travel Authorization (ETA) in order to enter the country.
The ETA costs £20 (about $24 USD)
Travelers can apply online through the official government website (https://www.gov.uk/eta/apply ) or on the UK ETA app.
To apply, you’ll need the passport you’ll travel with an email address, and a credit card or debit card. You’ll also need to upload a photo of the person applying.
Approval could take up to three working days but might arrive much sooner. The ETA will be linked to the traveler’s passport and valid for two years or until your passport expires, whichever is first.
Travelers can use the same ETA to enter the UK as many times as they want during that timeframe, and they only need to show their passport upon arrival at a U.K. airport.
