As of 2025, ALL U.S and E.U Passport holders are now required to obtain an Electronic Travel Authorization (ETA) to enter the United Kingdom. You can easily apply for one by clinking the link below, and it is recommended to do so 1-2 weeks before travel.

If you do not apply through the link below, please be sure that you are on the official .GOV.UK website and not a third party site which may incur additional fees.
