What are the new health insurance requirements for obtaining an O/A visa in Thailand?

: we are trying to understand this, at the date of the application for an O/A visa, the embassy wants proof of insurance for "a one year stay" from the planned date of entry, so you have to plan the beginning of the validity of your insurance in accord with your planned day of entry. I am sure all embassies and consulates are aware of this and will follow suit when they issue the O/A visa. Matthew did it perfectly right: he directed the insurance to start the validity on the day of his departure out of Germany. He only lost 2 days upon entry ( I guess 1 day was lost to the fact that February is 29 days this year, and the other is the arrival day counting as day 1). I think embassies are aware of this. Best is probably you have a proof of flight and the 1-year insurance validity starts on the same day . . so there will be no problem for Immigration at the airport to stamp you in for a full year
