The State Department has suspended processing passport applications seeking the gender marker of “X” and will only process and issue passports for people identifying as male or female, according to a department spokesperson.

It wasn’t immediately clear if already-issued passports that use “X” under the gender option will remain valid. A State Department spokesperson told NBC updates would be shared as soon as possible on the department's travel website.
