I just had mine approved, no health insurance, applied Thursday and received approval email just now, less than two days. When asked for health insurance info just upload photo of N/A written on a piece of paper, that’s what embassy advised and worked perfectly.
get a non O visa (over 50) from U.K. Thai embassy online e visa for £60. Gives you 90 days that you can easily extend in Thailand. No health insurance required for this, 100% confirmed directly from the embassy. Cheapest and simplest way to do it. Then free to review healthcare options without a visa restriction attached or go with travel insurance.
I’m in process of getting the 90 day non-O (over 50) in UK for myself and dependent spouse for wife. When I apply for the 12 month extension in Thailand can my wife apply at the same time?
