Entry requirements for London

As you are travelling from the United States to the United Kingdom, you must hold a valid passport for the duration of your stay. US citizens typically do not require a visa for tourism or short-term business trips of up to six months.

Upon arrival, you will pass through border control. While many travellers can use the automated ePassport gates for faster entry, ensure you follow the directions of the UK Border Force if you are travelling with children or require specific entry stamps.

London is a global hub for culture and history, offering world-class landmarks such as the Tower of London, Westminster Abbey, and the British Museum. You can spend your days exploring the diverse neighbourhoods of the West End or taking in the views from the South Bank along the River Thames.

For those interested in the city's green spaces, Hyde Park and Regent's Park provide expansive areas for relaxation amidst the urban landscape. The city's extensive Underground network makes it easy to navigate between these historic sites and modern attractions.
