Hello Sophie
I agree that it would be better for someone moving either to UK or to US, to explain it is an application for continuation of HRT as opposed to new prescription.
I wish you happiness on your move to US.
Hello again Bluelotus
Yes. If a local doctor refuses to prescribe hormones, then as you say you may register with GenderGP and afterwards arrange a "Shared Care Agreement" between your local NHSGP and GenderGP as I have, such that you may obtain your medication under NHS.
Good luck whichever option(s) you choose.
Hugs to you both
Pamela
