I got dtv its relatively cheap,easy,gives you as many returns as you want ,can't stay over 180 days,can get a 180 day extension though..if you want a bank account,drivers license it'll cost at a visa service
they're certified.theyll write you out a receipt for one years Muay Thai ,but can do whenever want,they helped me get mine in Vietnam a week ago.id much rather be in cm than bkk .
Most will tell you to be very careful about buying anything , might want to chat with a thai lawyer, much cheaper to pay a little beforehand than a lot after. Many will tell you to rent, it's cheaper easier in the long run, if something goes sideways not so much loss. I'm retiring here on and off, won't be buying anything.
