Passport Validity Rules (6-Month Requirement)
International routes typically need 6 months validity from arrival; domestic flights accept any unexpired passport.
Most international destinations expect your passport to remain valid for six months beyond the day you land. Domestic flights only need a passport that hasn’t expired yet, but because airlines must follow the stricter rule of the toughest transit country, they check the six-month buffer at the departure counter.
Key highlights
- Count six months from your intended return date; if the passport expires earlier, apply for renewal.
- Gather old passports with visas—you may need them for Schengen/US interviews even after renewal.
- Print your appointment receipt and keep digital copies in DigiLocker.
This buffer gives immigration enough confidence that you won’t overstay accidentally. If your passport expires a month into a three-month trip, the host country risks being stuck with a traveller the system can’t track. That’s why airlines would rather offload you at check-in than pay fines at the destination.
Some countries (Schengen, UK, Singapore) also demand blank pages for stamps or visas. If your booklet is almost full, renew it together with the validity issue—fresh booklets arrive within a week under Tatkaal.
Use the ‘return date + six months’ formula. If the resulting day falls after your expiry, you’re safe. If not, book a renewal slot immediately and carry the receipt to the airport in case the new passport arrives right before departure.
When allowed vs. when not
✅ When it's allowed
- •Set a reminder on your phone 9 months before expiry so you have cushion for busy seasons.
- •Use the Passport Seva portal’s police verification tracker to avoid last-minute surprises.
- •Carry passport photos and photocopies whenever you visit an FRRO or embassy.
🚫 When it's NOT allowed
- •Don’t book non-refundable international tickets if your passport is within the danger window.
- •Avoid stapling boarding passes to passport pages; it tears the lamination.
- •Don’t ignore minor damage—torn lamination + low validity equals instant denial.
At the airport
- ✔Carry both old and new passports if the new one arrived after you obtained visas.
- ✔Show evidence of renewal (SMS or acknowledgement) if you are flying domestically during processing.
- ✔Check blank pages: some immigration desks insist on two free pages facing each other.
