- UK travellers usually need an ESTA or visa to enter or transit.

Do you need 6 months on your passport for the USA?
No — not usually.
The USA does not normally require 6 months validity for UK travellers.
Instead, your passport should be valid for your entire stay.
Passport validity requirements for the USA
UK government guidance states that your passport should be valid for the length of your stay in the United States.
- Arrival: 10 August 2026
- Departure: 24 August 2026
- Passport expiry: 30 August 2026
This would normally meet the rule, but leaving extra validity is always safer.
USA passport checklist before you travel
For a direct UK to USA trip, passport validity is usually simpler than Schengen travel because the USA does not normally apply the 10-year Schengen rule or the 3-month-after-leaving rule to UK passport holders. The checks that catch people out are usually ESTA, transit, and passport changes after ESTA approval.
- Make sure your passport is valid for the whole planned stay.
- Apply for ESTA or the correct visa before travelling.
- Check that your ESTA details match the passport you will use at the airport.
- Check transit rules if you change planes outside the UK or USA.
Do UK travellers need an ESTA?
ESTA (Electronic System for Travel Authorization)
Most UK travellers visiting the USA for tourism, business or transit need an ESTA under the Visa Waiver Program.
- Apply online before travel
- Usually valid for 2 years (or until passport expires)
- Allows stays of up to 90 days
If you renew your passport before a USA trip
If you renew your passport after getting ESTA approval, check whether you need to apply again with the new passport details. Your travel authorisation and your passport details need to line up when you check in and arrive.
It is also worth checking your middle names, date of birth, and passport number carefully when applying for ESTA. Small differences between your passport and travel authorisation can delay check-in or boarding.
Do UK travellers need a visa for the USA?
You may need a visa instead of ESTA depending on your travel purpose, previous travel history, or length of stay.
ESTA is generally for eligible short visits such as tourism, some business trips, and transit. If you are working, studying, staying longer, or have a more complex travel history, check official US visa guidance before booking.
