proof of the 800k to apply for the 90 day non-o is only required in a couple offices Jomtien is one and at the moment you can’t open a bank account without a long stay visa so best to apply at home then get here open an account get your 800k in the account it needs to be seasoned for two months before the 1 year extension
You can extend once for 30 days but I believe depending on when you come it’s still 60 days visa exempt and you can extend that but it is going back to 30 days and DTV are pretty much all done online
don’t do it the insurance is close to useless just apply for a non-o and get here open a bank account deposit your 800k no police check no medical certificate or insurance
