wrong I have two passports as I travel international for my company ,I use one passport for Thailand and another for entry to the UK or other country if you don't need visa
if you mean me I have work permit for Indonesia and Brunei for your information,I don't work in Thailand only come back for 1 month at a time to see my Thai wife
airport only issue entry stamps and exit stamps ,they won't deal with transfer of visa from one passport to another ,go to proper immigration office get it done
Yes that's correct the initial 90 day Non-O visa has to have the 800,000 in the bank 2 month before applying,I did it in Bangkok in January 2021.,better to fly out other country then fly back in again
