Pursuant to Department of State regulations, applicants must establish their identity and citizenship when applying for a passport. Beginning June 30, 2021, U.S. citizens and non-citizen nationals were no longer required to provide medical certification of gender transition if the binary gender of M for male or F for female that they selected on their passport application did not match the gender indicated on their other citizenship or identity documents. Beginning April 11, 2022, U.S. citizens and non-citizen nationals became able to affirmatively self-certify a change in gender marker on their passport application forms and to select among three possible gender markers: M for male, F for female, or X for unspecified or another gender identity. The Department proposes to update its regulations governing applications for passports to reflect these changes in policy, consistent with the Department’s commitment to promoting the freedom, dignity, and equality of all people, regardless of their gender identity.
