Right Sir. The way I look at it, the money saved doing it myself IS the interest payment on the 800k. Plus a person can use 400K of that for investments about 7 months a year, correct?
I had great service, an excellent exchange rate, and VERY reasonable cost doing a simple bank-to-bank transfer. It was under $40 total for both bank fees. For $24,000. Took two business days, though they said 3 business days.
Wise is fine for under $1000. Above that it can get stiff.
No sir.......no health insurance required on a Non-O retirement visa. You may be thinking of a Non O/A visa. Very easy to get things confused in the byzantine world of Thai immigration rules, which even then changes in some of it's requirements from immigration office to immigration office. Plus even then a Thai immigration officer has a LOT of flexibility in dealing with any one applicant. I learned that the hard way.
