Hello BajanTsGyal, welcome to Susan's!
I am not familar with Dr. Sukit or Dr. Manrique, but I had GCS/GRS recently in Arizona with Dr. Ley at Toby Meltzer's clinic. I am super happy with the results.
My GCS was performed 6 months after i started HRT. The surgeon was aware of that, no issues. WPATH guidelines required by insurance carriers will be looking for a minimum one year living as female gender prior to GCS, and a couple letters from therapists of physicians (one of the letters will probably need to be a PhD.). If you desire GCS and haven't met with therapists who can provide the necessary letters prior to surgery, that's something you will want to start planning for.
The other thing to plan ahead for is permanent removal of hair from the surgery site. Since hair grows on a somewhat random schedule this often requires several months of electrolysis. Laser can significantly reduce hair density based on hair and skin color, but to reduce the risk of anything growing back I went with electrolysis. Some surgeons do not require hair removal, and and some do - this is something to discuss during your evaluation. I wanted to reduce the risk of potential complications so I spent a full year of electrolysis down there every two weeks before the surgery.
Since this was your first post I'll add information to help with navigation, and site guidelines.
