Rhode Island Passport Gender Marker Change Letter is a legal document used to change the gender marker on a Rhode Island passport. This letter is issued by a qualified medical professional confirming that an applicant has undergone a gender transition and the gender marker on the passport should be updated to reflect their gender identity. There are two types of Rhode Island Passport Gender Marker Change Letters: a letter from a physician confirming gender transition and a letter from a mental health professional confirming gender identity. Both letters must be signed by the medical professional and include their license number and the date of the letter. The letters must also include the applicant's full name, date of birth, and the gender marker requested on the passport.
