Every year, I spend 4 or 5 months in my wife's house in Thailand.
The texts on the embassy website are vague and imprecise.
For the 3rd year, I submitted an application for a non-immigrant O visa with health insurance covering the 4 months of stay. This time, it doesn't work anymore, and the embassy doesn't answer my question, even by email.
Looking at the websites of the embassies in Paris and London, I believe I understand that the reason it doesn't work is that the medical insurance must cover a full year.
Would that be correct?
