DTV_BegPecker you don't need any stamp entering or leaving the country you have the nationality and nobody will give you a stamp and many gates are automatic even in Thailand you can leave without stamp.
Nobody ever payed tax on foreign income and if then you have been stupid. Funny to read so many comments from people who don't know anything about Thailand and the laws here and command law
It was all the time hard to get a bank account in Thailand bc normally they do not speak English at the branches, I opened my first account 25 years ago on 30 day trip, over the last 15 years I had accounts in 7 different banks. All the DTV holders incapable to solve things in Thailand. You can still get bank accounts but you have to put efforts in it. Thailand is not a country for people who start whining and complaining when a problem pop up. Just solve it. Dress nice, go to bank tell them you want to open a account and don't give up, ask for the manager if they tell you you can't. Then go to the next branch if it not works. In Thailand you get everything but here in the group the biggest problem is tm30 or 90 days report what is in reality zero important for a dtv holder. Same like doing visas for kids under 14 years old.
