Following up on recent questions about the “X” gender marker on U.S. passports and the new CBP sex-field validation, here’s the most current summary:
In January 2025, President Trump issued Executive Order 14168: “Defending Women From Gender Ideology Extremism and Restoring Biological Truth to the Federal Government.” This order directed all federal agencies to recognize only two sexes, male and female, and to stop issuing new passports with an “X” gender marker.
The U.S. Department of State subsequently announced that new passport applicants would be issued documents marked “M” or “F” corresponding to their biological sex at birth.
However, existing U.S. passports with an “X” remain valid for travel and re-entry into the United States.
In June 2025, a federal judge issued a preliminary injunction in Orr v. Trump, requiring the State Department to continue offering passports with “M,” “F,” or “X” markers for certain class members while the case proceeds. So while new issuances are limited, some individuals can still legally obtain “X” passports under this ruling.
On October 14, 2025, CBP implemented its new system validation requiring airlines to transmit only “M” or “F” in passenger data (APIS). Any “X” entries return an error, forcing airlines to resubmit the data so most carriers are defaulting to “M” or “F” when processing travelers with an “X” passport (Air France and KLM, for example, default to “M”).
Updated advice for travelers with “X” passports:
- Their passport remains legally valid for international travel and re-entry.
- They should check with their airline ahead of time to confirm how gender data will be transmitted to CBP.
- Carry supporting documentation (e.g., ID or booking confirmation) that matches their passport details.
- Report any airline or airport issues through NAFSA IssueNet so they can track real-world impacts.

Executive Order: Defending Women From Gender Ideology Extremism And Restoring Biological Truth To The Federal Government (January 20, 2025) has provisions with implications for language and categories on government forms, records, and documents, including U.S. passports. Extract:
"The Secretaries of State and Homeland Security, and the Director of the Office of Personnel Management, shall implement changes to require that government-issued identification documents, including passports, visas, and Global Entry cards, accurately reflect the holder’s sex, as defined under section 2 of this order; and the Director of the Office of Personnel Management shall ensure that applicable personnel records accurately report Federal employees’ sex, as defined by section 2 of this order."
Implementation of this executive order by Secretary of State Rubio will impact the content of this NAFSA advisory. See NAFSA's page for more information on this executive order.
U.S. citizens have the option to select “X” as their gender when applying for a U.S. passport book and card, instead of “M” for “male” or “F” for “female. This option has been available since 2022 when the U.S. Department of State.
