Visas & documents
What will the border ask for?
Entry rules depend on your passport, where you're going, how long you'll stay and sometimes where you've been. Check them before you buy a fare — airlines will deny boarding if your documents don't match the destination's rules.

Check by passport & destination
Passport validity
The six-month rule
Many countries require your passport to be valid for 3 or 6 months beyond your planned departure from their territory, and some require blank pages. Check yours.
