"Change of sex" is a medically vague term so I believe we have to contact the MEA or embassy officials to see what they can do for us. From my conversations with the consulate in Houston, I don't think they have any clear policy of what constitute a sex change and how 2014 NALSA effects passport gender change. If you can get more information then please post here.
