American citizens now need a UK Electronic Travel Authorisation (ETA) to travel to the United Kingdom. It replaced the old visa waiver for US passport holders and is required for tourism, business visits, and transit through the UK.
Your UK ETA is linked electronically to your US passport and is valid for multiple trips over 2 years, or until your passport expires — whichever comes first. Each visit can last up to 6 months.
The ETA does not guarantee entry — a Border Force officer will make the final decision on arrival.

The UK ETA is the standard entry authorisation for US passport holders visiting England, Scotland, Wales, or Northern Ireland for short stays.
A UK visa application is required for Americans planning to stay longer than 6 months or travelling for study, work, or settlement.
