Matthew Thompson One day overstays do not even attract a fine such is their low level of importance. Michael Dawson is quite correct. It's no big deal. Best to avoid of course, but it sure beats a trip to immigration and a 1900 baht extension for one day
Correct. I'm a regular visitor home (about every 18-24 months) to visit family so it suits me perfectly, as it does many others, but if your plan is to remain ongoing in Thailand, you are best to have the standard O retirement visa.
You don't renew every two years. You need to return to your home country and apply for a new OA. I did it this way before covid. Lived in Thailand for seven years. Never was required to transfer money, never visited immigration office. It was brilliant. The Golden Era
