On March 31, 2023, USCIS published a Policy Memo which announced:
“U.S. Citizenship and Immigration Services is updating policy guidance in the USCIS Policy Manual to clarify that, effective immediately, USCIS will accept the self-identified gender marker for individuals requesting immigration benefits. The gender marker they select does not need to match the gender marker indicated on their supporting documentation.
The update also clarifies that people requesting benefits do not need to submit proof of their gender identity when submitting a request to change their gender marker, except for those submitting Form N-565, Application for Replacement Naturalization/Citizenship Document.
Benefit requestors seeking to change their gender marker after their initial filing should refer to the Updating or Correcting Your Documents webpage. Currently, the only gender markers available are “Male” (M) or “Female” (F). The U.S. Department of Homeland Security (DHS) is working on options to include an additional gender marker (“X”) for another or unspecified gender identity. USCIS will update its forms and the Policy Manual accordingly.”
