Short answer
What is the six-month passport validity rule?
The six-month rule means some countries require your U.S. passport to be valid for at least six months after your planned departure date. If your passport expires too close to your return, airlines may deny boarding and border officials may refuse entry even though the U.S. allows you to hold a passport until its expiration date.

Full answer
The U.S. does not require you to have extra validity to leave the country, but other countries set their own entry rules. Common destinations with the six-month rule include China, Brazil, India, Thailand, and most of Southeast Asia and the Middle East.
The Schengen Area generally requires three months of validity beyond your planned departure. Canada, Mexico, and many Caribbean nations follow the same validity rule as the U.S., but always confirm the latest requirement before booking.
The safest approach is to renew any passport that expires within six to nine months of international travel. That gives you time for processing and avoids last-minute stress.
