United Kingdom profile
United Kingdom is applied as the destination and its current U.S. Department of State destination page is linked. A preset, when shown, remains an unconfirmed planning reference until itinerary, airline, transit and visa checks are complete.
- U.S. State Department reference: passport valid for the duration of the planned UK stay.
- Passport condition, blank pages, identity details, visas, transit-country rules and carrier boarding checks can override date arithmetic.
Some destinations require validity beyond entry and others beyond planned departure. The exact current destination rule—not the phrase “six-month rule”—sets the anchor and amount. Review note: Check the destination's current official passport-validity rule.
Context matters.
- The U.S. Department of State warns that some countries require at least six months beyond travel, but requirements vary and airlines may deny boarding.
- Check the destination's official entry page, the State Department travel page, transit countries, visa terms and the operating airline shortly before travel.
- Damage, insufficient blank pages, a name mismatch, visa conditions or emergency-travel-document limits can override otherwise sufficient calendar validity.

The calculation guide and this source trail show what the result means, where the rule came from and when it was last reviewed. This is source-and-calculation QA, not a claim of medical, legal, tax or other professional review; time-sensitive decisions still belong with the linked authority.
