Don't quite know what to tell you, even AI got it right when I asked when the 100K USD mandatory insurance took effect for OA visas
The requirement for the Thai Non-Immigrant "O-A" Visa to include $100,000 (approximately 3 million Baht) in health insurance coverage, specifically including COVID-19 treatment, officially began on October 1, 2021. While the change was confirmed by the Thai government in June 2021, and announced for implementation around that time, the implementation date for the new, higher coverage was set for October 1, 2021.
Most all consulates the world over require that 100K USD mandatory insurance many of them require it through a Thai carrier because foreign carriers will not sign the foreign insurance certificate
Well, wherever you stay, make sure that person files a TM 30 on you showing your registered as staying at that address and then when you're 90-day report comes up file your 90-day report at the immigration office that serves the area where you're staying.
yep, they are close BUT the way you can tell is the 90 day report receipt is now almost always hard printed on it's own paper, they don't tear off the bottom and stamp the next 90 day report date on it
believe it or not some offices DO require you file a new TM30 with them for domestic travel too 😕 BUT most don't, you have to check with your office and see what they say
