. There have been conflicting reports about IOs requesting insurance when entering the country. Worse case scenario is you get stamped in for 30 days, giving you that time to organise insurance and present the proof to the authorities who will then extend the admitted to stay for the full year. There's been no reports of people being denied entry. If you apply for an extension in Thailand you will have to provide proof of insurance, and if you apply for a new OA in your own country you will also have to provide proof of insurance
