Can I go? Entry and visas
From GOV.UK, for United Kingdom passports, updated 18 August 2026:
To enter or transit through the US, you must have either an Electronic System for Travel Authorisation ( ESTA ) or a visa.
The US State Department has more information on visas.
Travellers whose sex on their passport differs from their sex recorded at birth should contact the US Embassy or a consulate in the UK for further advice.
Passport validity
To enter the US, your passport must be valid for the length of your planned stay.
If you’re travelling through another country on your way to or from the US, check the entry requirements for that country. Many countries will only allow entry if you have at least 6 months validity remaining on your passport.
