I had the same question and went for the non O applied from the netherlands. The main reason for my decision was the fact that i can ‘choose’ the health insurance which suits me. I went for a dutch insurer company OOM. For me its a better insurer for a reasonable price compared to the list of insurers you can choose from if you go for the non OA. I was kinda stuck between a rock and a hard place concerning this topic but a good health insurance gives me a peace of mind if, fingers crossed, the sh*t hits the fan….😏
I am moving to Bkk in august. Goodluck Bob with your planning and decisions regarding your immigration
