Your 90 day visa is a single entry visa. Once you enter Thailand you no longer have a visa. It’s used. Finished.
What you have is an entry stamp allowing you to stay for 89 further days (entry day is day 1).
If you want to leave and keep that entry stamp “alive” you’d need a re-entry permit. On return you’d be stamped in for the exact date you were originally given.
Each entry needs a TDAC. Each time you return your house owner (or hotel) should in theory file a TM30.
Yes on each new entry you’d be given a new 60 day exemption stamp.
That said you can’t live in Thailand by constantly border bouncing, but what you are doing is a typical tourist type thing so should have no issues whatsoever.
It’s almost impossible these days to open a bank account by yourself without a long term visa. You may find an agent that can help you but even some of them are saying no chance.
Get a Non O before you come and during the first 30 days open the account and transfer 800k. Then when the money has been in for two calendar months apply for the year extension.
Not sure what you’re asking here. Did you apply to convert your visa exempt entry (or tourist visa) to a in country Non O visa? Or do you mean you’ve applied online via the evisa system for a Non O
I have no idea of your nationality but if you’re Israeli then definitely not. Many other countries passport holders could but from reports on here it’s not a “best choice” of embassy/consulate to do so.
Laos, Cambodia, Vietnam are all alternatives that you may want to consider. You need to stay in whatever country you apply from until the visa is granted or you’ll risk the application being denied.
