Entry requirements for London

British citizens and those with right of abode in the UK do not require a visa. Travellers from the United States visiting for tourism or short stays usually do not need a visa but must present a valid passport for the duration of their stay. It is advisable to check the latest UK government entry requirements before travel, as border formalities can include the use of eGates for eligible passport holders.

Ensure your passport is in good condition and has at least one blank page for entry stamps. If you are travelling on a different passport, you may need to apply for a Standard Visitor visa or an Electronic Travel Authorisation (ETA) depending on current regulations.
