Can't understand the crap this guy is getting for asking a detailed question. Not everyone understands the complicated process. So hes been martied to a Thai for years, living in the UK. This is not about a UK visa, which btw was non existant 25 years ago! Its about the ever changing and multi choice landscape of a Thai visa! It can be easier to ask for layman's terms in a group dedicated to the subject. Unfortunately this group is full of arrogant arseholes! Chill out, you are going to get questions about visas in a group called Thailand visa advice!!! or shut your trap or better, jog on!
I would suggest Ryong or Sirasha. Both busy Towns, near Bangkok, on the coast, international schools with large expat communitys but away from the Tourist hotspots.
I don't think foreigners can do jobs Thais can do, regarding your wife. And all the old farang men already have young carers, sorry GFs! 😅
