A lot of people are offering incorrect information here so be cautious about soliciting tax advise on Facebook. Do your own research.
The situation as I understand it is, Thailand will tax your remittances into your Thai bank accont if you are a 'tax resident' at the time of the transaction. There are perfectly legal work-arounds, but you still need to know what you're doing.
I just saw a blind Thai woman on the BTS last week. She seemed to be getting about on her own OK, the security guards helped her into the train and I helped her locate the grab pole to steddy herself. Security guards in Bangkok are everywhere and they are very helpful, unfortunately few speak English.
Sorry I could not answer your question but I wish you the best experience in Thailand.
