Changing my name was the easiest government-related thing I've ever dealt with. Hell, changing my name was 10X easier than just PICKING UP my foodstamp card after I was approved.
I went into the office, signed some papers and paid, then she scheduled my hearing for the next day. I was so nervous because I had never been to court before, but I walked in, the judge called me to stand up, I said that I was transgendered, he said "Sounds good", stamped a paper and told me I was done. Took less than 10 minutes. The hardest part of the process was saving up the money and finding the building haha!
