A post to give information only. Just re entered Thailand at Phuket International Airport. I have an OA visa issued July 2019. This was my third entry on this visa but the first after the 31st October. Although I do have health insurance obtained via the government approved website, after careful inspection by the polite and efficient officer, I was not asked any questions about health insurance or to prove I had any, and was stamped in for 365 days (Jan 6th 2021).
