General Update:
Much has been written regarding changes effective April 1, 2019, to the way funds can be transferred from abroad to satisfy Thai Immigration.
In March 2019 my monthly money transfer from Schwab to Bangkok Bank New York came into my Bangkok Bank Thai account listed as FFT (Foreign funds transfer). As I understand it, Thai immigration requires those funds come from abroad.
Without making any changes, in April 2019 my monthly money transfer from Schwab to Bangkok Bank New York came into my Bangkok Bank Thai account also listed as FFT (Foreign funds transfer).
So, for some of us months of concern was undue. I am relieved and hope other people might find this helpful.
