Why "not expired" is not the same as "valid enough to travel"
Many travelers assume any unexpired passport is fine for a trip, but immigration rules in many countries are based on remaining validity at the time of entry, not simply whether the passport has technically expired yet. A passport expiring one month after your return flight can still fail a destination's six-month rule and get you denied boarding before you even leave home.
This is general travel information, not a guarantee for your specific trip
Passport validity requirements, renewal processes, and reminder services differ by country and can change without much notice. Always confirm the current requirement directly with your destination's embassy, consulate, or your airline shortly before departure rather than relying on a rule of thumb.
Frequently Asked Questions
Is the "six-month rule" required by every country?
No. It is common but not universal -- some countries only require validity through your actual stay, while others require six months or more beyond your departure date. Always confirm the specific requirement for your destination before booking travel.
Can I still use my passport for domestic travel if it is close to expiring?
In many countries, yes, since domestic travel typically does not involve the same remaining-validity checks as international entry. Rules vary, so check your own country's guidance if you are unsure.
