Your passport dates are checked in your browser and never sent anywhere.

Entry rules change without notice and airlines make the final call — verify with your carrier or the destination's embassy before you fly.

The rule, in one minute

Immigration authorities want a buffer on your passport in case you overstay, fall ill, or get stranded. So instead of asking "is it valid today?", many ask "will it still be valid six months from now?" — and your airline enforces the answer at check-in, because carriers are fined for flying in passengers who get turned away.

But "the six-month rule" is really three different rules:

Six months from entry
The most common form — Thailand, Indonesia, China, India, the UAE and most of Southeast Asia and East Africa. Your passport must be valid six months past the day you arrive.
Three months beyond departure
The Schengen area's version — plus a second clause people miss: the passport must have been issued within the last ten years when you enter.
Valid for the stay
The UK, US, Canada, Japan, Australia and much of the Americas only require validity through your trip — though a thin margin still invites questions.

What this means for your Montenegro trip

For a trip arriving August 15, 2026 and leaving August 29, 2026, Montenegro needs your passport valid until November 29, 2026 — 3 months beyond the day you leave.

Montenegro passport questions, answered

Does Montenegro require six months' passport validity?

Montenegro requires your passport to be valid for at least 3 months beyond your intended departure. Like Schengen, the passport must also have been issued within the last 10 years.

Is Montenegro's rule counted from arrival or departure?

From departure: count 3 months from the day you leave Montenegro. Your passport must stay valid until then, and your airline checks it at your first check-in.

When should I renew my passport before a trip to Montenegro?

Add 3 months to your departure date: if your passport expires within about a month of that point, renew before you fly — under 30 days of margin is where discretionary refusals happen.

Who enforces the rule when I fly to Montenegro?

Usually your airline, at check-in. Carriers are fined for delivering passengers who get refused entry, so agents verify your passport against the industry Timatic database before issuing a boarding pass — most travelers caught out never reach Montenegro's immigration desk.
