I tried to apply for mom today, it required to buy insurance with outpatient 40,000, and inpatient 400,000 baht. Is it only need to buy for covering that 90 days or if you once use this sort to apply non o, when change to 1 year retirement visa in Thailand also need to buy. But my mom is too old buy, then not sure will be failed to apply this non o 90 days.....
