USCIS Policy Manual: only two sexes, determined by birth certificate, on all immigration documents

USCIS updates its Policy Manual, effective immediately and applicable to all pending and future benefit requests, to state that USCIS recognizes only two biological sexes, male and female; determines sex from the birth certificate issued at or nearest the time of birth (with secondary evidence where that certificate shows other than M/F); removes the "X" marker from all USCIS forms and documents (green cards, EADs, naturalization certificates); and replaces "gender" with "sex" throughout. USCIS states it may issue documents bearing a sex different from the one the requestor selected, with delays possible for mismatched filings. (See also section 7.)
