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.

Important: If you are travelling via another country, that country may have stricter passport rules. Always check your full route.

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.

Example:
  • 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.
