Hello, I live in Thailand on marriage visa and I traveled back my home country two months ago and I am applying for Thai pass now to come to back to Bangkok on Test and Go program, I am confused about insurance, as I suppose to arrive on 11 March while my visa finish on 24th March, so shall I buy only insurance for one month or it must be 1 year because I'll renew my visa again for one year when I come back.
TLDR : Answer Summary
When applying to re-enter Thailand on a marriage visa via the Test and Go program, you only need to purchase health insurance for the duration of your stay as indicated on your entry stamp, which is one month in this case. While planning to renew your visa for a year upon your return, there is no requirement to have insurance for the full year before entering Thailand.
