FAQ
Do all countries require six months on a passport?
No. Some do, some do not, and the date rule can differ. Check the official destination rule.
Does a visa override passport validity?
No. A visa or ETA does not usually fix a passport that fails the validity rule.
Should I renew if my passport is close to expiring?
If the destination or airline requirement is close, renewal is usually safer than relying on a borderline interpretation.
