Overview
- After a 90‑day implementation window, APIS now returns a “respuesta X” prompt when a non‑binary marker is entered, requiring selection of M or F to complete the transmission.
- The requirement stems from Executive Order 14168 directing federal records to use only male or female sex markers, extending in data processing to passports, visas and Global Entry credentials.
- CBP says passports bearing an “X” remain valid until expiration, and the pre‑flight sex selection is not an added criterion for admission to the United States.
- Airlines must ensure pre‑departure data uses M or F, with CBP indicating carriers will not face administrative penalties for marker mismatches during verification.
- The rule applies exclusively to international flights and does not change procedures for domestic travel.
