Interesting point! Why would then not just every retiree who is unable or unwilling to take out an insurance switch from o-a to o!? Problem solved. What is the disadvantage of having an o visa vs an o-a visa?
I am getting confused: is the health insurance only needed for the initial o-a visa needed or also when holding an o-a visa already and doing annual extensions in thailand!? maybe i misunderstood but i believe first it was said that only for the initial visa the insurance is needed and now it changed to both?
