They seem to have a problem with people doing 60 exempt plus 30 day extension and then bouncing I’ve been watching people that bounce without the 30 day extension have had far less issues
No it’s takes time to get any Thai a visa best dealing with the embassy in Bangkok but to be honest you cutting it close even if she meets the requirements witch is basically a good reason to return ,money in the bank,own a home,have kids a job to return too ect.
800k in a Thai bank in your name and it can be several Thai banks but it has to be accessible so no bonds,don’t forget the insurance ,but if you have the 800k why not leave come back and switch to the non-o there’s no insurance needed only if you want it
