I’m sorry, I still don’t under the question. This visa is for long term stay in Thailand. You get 12 months on entry. If you leave and re-enter just before the original visa expires then you can ‘stretch’ the visa to nearly 2 years BUT there’s no way of avoiding Extensions of Stay after that.
The only other option is to go back to your home country and get a brand new visa.
Border runs are used by people who can’t get long term visas but want to ‘cheat’ the system by getting multiple visa Exempt entries. In any case, land borders are currently closed.
First, Health insurance. Although it is now required for the initial application for Non O ‘for Retirement’ in your home country it is NOT required if you get it in Thailand NOR is it required for each subsequent Extension of Stay.
Second, the 800k location is the same for Non O and Non O-A. It DOES have to be in a Thai bank for Extensions of Stay.
Yes, hopefully more things will be confirmed after tomorrow’s meeting - though it might then go to Cabinet on Tuesday. It’s beginning to shape up, at least.
