I am researching this so wanted to let others know even though I don't use Visa Journey. So far I have found only 3 options in Bangkok:
Baan Thai Immigration Solutions – Owned by an American lawyer, good reputation.
Siam Legal – Well-known but expensive, with mixed reviews.
Rita Visa Advisor – Visa consultant focused on K1 couples, good reputation.
I haven't personally used any of them yet, but since I did the research, I’m sharing it here. Hope it helps.
