Passport Validity: Recommended six months beyond date of entry into Turkey
As of January 1, 2015 foreigners traveling to Turkey should carry a passport or travel document with an expiration date at least 60 days beyond the duration of stay of expiration date of their visa, visa exemption, or residence permit. Turkish tourist visas are generally valid for six months; therefore U.S. citizens should have a passport that is valid for six months beyond entry date. Passports should have enough blank space to allow for Turkish entry and exit stamps. If there is not enough space for entry and exit stamps in your passport, you will be denied entry into Turkey.
What happens if you don’t have enough validity on your passport?
If your passport validity is less than 60 days, you will not be allowed to enter Turkey.
If your passport has a validity of 60 to 75 days, you will be allowed to enter Turkey with an approved stay of 10 days.
If your passport has a validity of 75 days to 6 months, you will be allowed to enter Turkey with an approved stay of 15 days.
If you stay longer than your approved stay, you will be subject to a fine.
