My experience in Laos ..Vientiane ....was I had my Australian bank account that I use all the time when there ...as have an a/c here ..but didn't mention that ...so I transferred enough money to be over 500,000..I converted it to baht in my Australia bank ...with yellow high higher ...all she asked was ..your mobile account ..where's that ...I asked what's you mean .... mobile ...she ask for everyday transactions...I told her that I not use my card ..just transfer into my partners account..she is Thai ..and I put out 40,000b when I need money ...pick up my visa 2 days later ..did that transfer ...528,000 b was 3 days before I went to put my forms in ...I also had lots of activity in that account ..for buying stuff online , money transfers stating .."Thai Money" ...not over counter ..very rarely purchase products over the counter with my card ..
yes ..I know a few people who had DTV done whilst in Thailand ..but with an agent who charges ..1..was 18,000 b plus the 10,000b other was 25,000b including the 10,000b for visa ..other guy said said he had an agent but didn't say the fee ...I did mine by myself at Vientiane...stayed 5 days ...and entered Thailand with DTV ..cost 10,000 visa fee ....petrol to border and back 1800b, hotel .. 5500b plus beers and food ..which i would have paid anyway, as I go for rides anyhow but enjoyed the place, was bit boring but had a book 🍺
Or Come in on 70 day stamp ...a flight to Lao , Vietnam or Malaysia ...Cambodia...when your DTV arrives .... I've just done Vientiane for that visa ..as I have a bike, I went for a ride over from Chiang Mai..I not sure but I think here you can go in and out in one day ...with DTV ..but maybe not north northern Kaos
