I used business account and was asked to prove it was my name which it doesn’t on paper work so at interview I showed them a business bank card with my name on. This was at Vientiane, Laos embassy.
most you can do online but in Laos you must go in person. I went to the bank in Laos and swapped the currency to baht. Pretty straight forward. Just need a passport.
always get one at Laos it’s mandatory unfortunately. Just want to see proof of money on your phone and check the bank account is actually in your name. Other questions just regard work and what you want to do in Thailand. Also to show proof of clients payments in your bank account.
