I´m heading for PAI in 3 weeks. I only presented 1 letter of recommendation from a gender therapists, and that is enough.
You still need to see 1 psychiatrist in Thailand, before the surgery, but what I´ve understood, is that it is more or less a formality, due to the law in Thailand.
By the time of my surgery, I´ve been on HRT for about 8 months and RLE for 9 months. It was ok for PAI and few other places in the world also, don´t use that requirement, as long as you have the letter. And as long as you are paying the surgery. Of course public healthcare, here also, places all kind of obstacles that you need to jump, when someone says so.
I´m still thinking of taking my prescriptions with me, even though they are in a language that they cannot understand.
