Gender Marker Change Letter
To change the gender marker on federal documents (Social Security, passport, immigration, etc.), you will need a signed original letter from a medical doctor. You can use the same letter to update the gender on a NYS Driver's License or State ID card, as well as New York City birth certificates. Give this sample letter to your doctor.
