OA extension with Insurance - Still failed ! in Thai visas, residency and work permits Posted Friday at 02:51 AM · Edited Friday at 02:56 AM by UncleMhee 7 minutes ago, zaZa9 said: I was told outright by a Retired Immigration Officer on Monday that the law is written clearly enough and it says that Insurance is NOT required for existing Retirement Extensions based on an original O-A Visa and any office saying its required is , "Not doing correct thing ." This is what all on pre October 31 2018 O-A's would like to know unequivocally......well I would at least; before May would be good! Thanks for posting @britishjohn; but anecdotal doesn't cut it. Just sayin'
