I just got back from my 90 day check in at Jomtien Immigration! I have a one year multiple entry OA from Canada! It took 5 minutes tops and I was out- I asked about the mandatory health form for when I come back next August - my visa runs out July 21/2020.- the officer told me to come back before it runs out and they would renew it for another year- I asked again about the mandatory insurance which I get anyway and he gave me these forms- if I renew back in Canada I can leave my 800000 in my Canadian Account- I hope this helps some of you!
