As of October 2021, it seems that the State Department no longer distinguishes between a transition that is “in process” and one that is “complete.” This distinction was originally intended for applicants who had recently begun a gender transition and needed documentation to travel abroad, before the requirement for undergoing a surgical procedure was removed. As there is no longer any requirement to provide medical certification to justify a change in gender marker on a U.S. passport, these limited validity passports should no longer be issued in gender marker change cases.
If you have been previously issued a limited validity two-year passport, you should submit a completed Form DS 5504, Application for a U.S. Passport (Name Change, Data Correction and Limited Passport Book Replacement) to extend to a full validity passport. No additional fee is required unless you request expedited service.
You may mail in your application to the National Passport Processing Center or drop off your completed application and required documentation to your local State Department Office. Note that any documents you mail in will be returned if not damaged.
