On February 14, 2025, the State Department (DOS) issued guidance announcing a new policy on sex markers in U.S. passports, pursuant to the Trump Administration’s executive order declaring that the U.S. government will only recognize the two binary sexes (male and female). Under the new policy, DOS will only issue U.S. passports that contain either an “M” or “F” sex marker, and will only issue new passports that match the biological sex assigned at birth. DOS will no longer issue U.S. passports or Consular Reports of Birth Abroad with an “X” marker.
