Is this right? That *tomorrow* they're going to start denying, in some way or another, X gender markers at US borders / on US passports? https://www.gtlaw-insidebusinessimmigration.com/u-s-customs-and-border-protection-cbp/cbp-enforces-binary-sex-codes-and-enhanced-us-passport-validation-in-apis/
It's not quite clear what they're going to end up doing. Will they "infer" a binary gender, or will they deny the validity of the passport?
