Passports, Visas and Entry Rules
The Six Month Passport Rule: How Passport Validity Works for Travel
Why an unexpired passport is not always enough to travel, and how to check the validity rule for the country you are visiting.
The short answer: many countries will not let you enter unless your passport is valid for at least six months beyond the date you arrive, or in some cases the date you leave. Other countries only require your passport to be valid for the length of your stay, or for three months after departure. Airlines check these rules at check in and can refuse to board you, so confirm the rule for your destination before you book.
What the six month rule is
The six month rule is an entry requirement set by individual countries. It means your passport must not expire within six months of a reference date, usually your arrival date. A passport that expires in four months is valid for travel at home, but it may be refused at the border of a country that applies the six month rule.
Countries use validity rules so that a visitor's passport cannot expire while they are in the country, and so that the passport remains usable if the visitor's stay is extended.
The common types of validity rule
| Rule type | What it usually means |
|---|---|
| Six months beyond arrival | Passport valid for six months after the date you enter |
| Six months beyond departure | Passport valid for six months after the date you plan to leave |
| Three months beyond departure | Common in the Schengen area for visa exempt visitors |
| Valid for the duration of stay | Passport must simply be valid until you leave |
Rules can also depend on your nationality. Some countries have agreements that allow citizens of certain countries to enter with a shorter remaining validity.
The Schengen area: a common source of confusion
For short stays in the Schengen area, the general requirement is that your passport was issued within the last ten years and is valid for at least three months after the date you intend to leave. Because travelers often visit several countries and change plans, many advise treating it as six months to be safe. Check the official EU travel information site and the embassy of the country you are entering first.
Other passport requirements that catch travelers out
- Blank pages. Some countries require one or two blank visa pages.
- Damage. Water damage, torn pages or a damaged photo page can make a passport invalid.
- Name match. The name on your ticket should match your passport exactly.
- Transit countries. Validity rules can apply even if you only change planes, depending on the country and whether you pass through immigration.
How to check the rule for your destination
- Find the official entry requirements on the destination government's website or its embassy site.
- Cross check with your own government's country page. US citizens can use the country pages at travel.state.gov.
- Check transit countries the same way.
- If your passport is close to the limit, renew it before you book nonrefundable travel.
