CBP Enforces Binary Sex Codes and Enhanced US Passport Validation in APIS
Sex Field Requirements: Effective Oct. 14, 2025, CBP systems will only accept “M” (Male) or “F” (Female) in the sex field of APIS transmissions. Any other characters will result in an “X Response-Insufficient Information” error, requiring airlines to resubmit the passenger data with corrected information.
You meant the scenario is for American or resident non binary that will not be able to leave the country via plane because their current passport got X?
Correct, if I’m understanding it correctly, I am not a lawyer, it will also prevent you from entering the country via plane. They want M or F only.
I’m also pretty sure preventing a citizen from entering the country violates some international law, but I also could be wrong about that.
Thanks for the clarification. That is how I understand as well. Also not a lawyer.
