What is a passport validity rule?
Also called six-month rule
Many countries require your passport to stay valid for a set period — commonly six months — beyond your travel dates, and to have blank pages for stamps. A passport that's still in date can still be refused if it falls short of this rule.
The exact period varies by destination, so check your passport's expiry against each country's requirement well before you travel — renewing takes time.
