I am a terrible example because I sorta fell into full time about 6 months earlier than I had planned and about a month later started the process of name change, Still waiting for the court house to get back to me, I also got a note from my doctor to change my gender marker and will be going to change social security card shortly after the name change goes through, then a new license. (massachusetts BTW) so all in all if things proceed at the speed I hope they do I am looking at about 2-3 months from the first time I was in public as myself to getting my licence changed to read Serena, Female.
but from what I have seen thats very very fast, everything has been, then again after decades of needing this its a good thing.
