I was thinking if I go to Thailand, I will first try to find an immigration office that would accept 300,000 baht transferred into a Thai bank and my monthly (US Social Security) international transfers of $1,400 for 2 or 3 months, to do the combo method.
But make sure before I go to Thailand, I have enough money for living expenses and the 800,000 baht in my bank account at home, in case I need to transfer that also, to go the full 800,000 baht route.
Are there any visa service companies in Bangkok that could maybe help me?
