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.
Yeah, I hadn’t heard about it happening before Trump took office again but it wouldn’t surprise me at all if some of the more ideological rank and file workers started preemptively slow walking some trans people’s passports they got their hands on once he won before it became a top down directive.
Either way the Republicans have been doing a ton of boundary pushing with what they can technically legally do since taking control again and this is definitely aimed at being a legal gray zone way to basically invalidate trans people’s passports. And of course now we can’t even get nation wide injunctions to stop it. Sure is great
