This information is for people travelling on a full ‘British citizen’ passport from the UK. It is based on the UK government’s understanding of the current rules for the most common types of travel. 

You must have the correct approval prior to travel. This will be either a valid US visa or Electronic System for Travel Authorisation (ESTA), depending on your personal circumstances and purpose of travel.  

US authorities enforce entry rules strictly. If you do not have the correct immigration status, or if you breach the terms of your entry, there is a risk you may be detained, refused entry, or removed (deported). Overstaying your permitted time in the US can also lead to detention and future bans on re-entry.  

A valid ESTA or visa does not guarantee you will be allowed to enter the US. Authorities may refuse you entry if, for example, they believe you plan to stay longer than permitted or have provided inaccurate or incomplete information. The US may change the conditions to travel to the US at any time without prior notice. 

If you’re not sure how these requirements apply to you, contact the US Embassy or a consulate in the UK. See information from on entry for international visitors.
