Why it's regulated
Passports are how border authorities verify identity, nationality, and the right to enter, supporting immigration control and security. Validity and visa rules let countries manage who crosses their borders.
Typical allowance
Many countries apply a 'six-month rule' requiring your passport to stay valid for at least six months beyond entry, though some require only three months and a few just validity through your stay; confirm the exact requirement for your destination.
