The six-month passport rule · 🇺🇸 United States

Does the United States have a six-month passport rule?

No — the United States has no six-month rule; your passport only needs to stay valid through your trip. Airlines can still be stricter, so check your dates below.

The United States requires your passport to be valid for the whole of your stay. The default US rule is six months beyond your intended stay, but nationals of the 100+ "Six-Month Club" countries (CBP list) — including the UK, EU, Canada and Australia — need validity only for the period of stay.

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 United States trip

For a trip arriving August 15, 2026 and leaving August 29, 2026, the United States needs your passport valid through August 29, 2026 — your departure day.

United States passport questions, answered

Does the United States require six months' passport validity?

The United States requires your passport to be valid for the whole of your stay. The default US rule is six months beyond your intended stay, but nationals of the 100+ "Six-Month Club" countries (CBP list) — including the UK, EU, Canada and Australia — need validity only for the period of stay.

What are the United States' passport expiration rules?

Your passport can expire any time after your trip ends — the United States only asks that it stays valid until the day you leave. Airlines still prefer a margin, so don't cut it to days.

My passport expires in five months — can I still go to the United States?

Yes — the United States only asks that your passport outlives the trip, so five months is plenty. Watch the rest of your itinerary instead: onward destinations with six-month rules are what catch travelers out.

Is any validity buffer required beyond the trip?

No buffer — your passport just has to remain valid until the day you leave the United States. A thin margin can still draw questions at check-in, so treat a near-expiry passport as a renewal prompt.

When should I renew my passport before a trip to the United States?

If your passport expires within a couple of months of your return date, renew first. Airlines apply validity rules more conservatively than the United States' official requirement, many onward destinations want six months, and routine renewals take four to ten weeks in most countries.

Who enforces the rule when I fly to the United States?

Usually your airline, at check-in. Carriers face fines — typically €3,000–5,000 per passenger — plus the cost of the return flight when they deliver someone who gets refused entry, so agents verify your passport against the industry Timatic database before issuing a boarding pass, and they don't round up: one day short can be enough. Most travelers caught out never reach the United States' immigration desk.
