Portolan Passport validity

How many months of passport validity do you need for USA?

To enter USA, your passport must be valid for at least 6 months.

The rule

Check your own dates

The rule is one thing; whether your passport clears it on your travel dates is another. Turkey counts 150 days, not five months. Costa Rica counts one day. Schengen countries check two rules at once.

What happens if you do not meet it

Airlines check validity at check-in and can refuse to board you — they face fines of 3,500 to 10,000 US dollars for carrying a passenger who is then refused entry. One denied boarding costs the traveller between 1,200 and 2,400 US dollars in lost fares, hotels and rebooking. In 2025, 1.2 million people were denied boarding or entry over passport problems, and 40% of those were validity.

Source, word for word

To enter the US, your passport must be valid for the length of your planned stay. If you're travelling through another country on your way to or from the US, check the entry requirements for that country. Many countries will only allow entry if you have at least 6 months validity remaining on your passport.
