When I purchased mine 8 years ago, they were quite specific that the transfer has to be in foreign currency, and they will convert to THB at the Thai bank.
Question: would it not be easier to just have an account for fixed deposit of 800k Bahts for the year (or longer), without worrying about it dropping below 400k? Would this meet the requirement for applying and renewing (reapplying) for Retirement Visa? Then have a separate account for everyday use.
Thank you, everyone for your advice. I shall go to BKK Immigration to report in-person before my 90 days is up! I got Multiple Entries permit already. Thanks again so much!!!
