The reason is the Thai bank account you are sending your salary to, this could have been the red flag.

The DTV is a tourist visa class, and you can't even open a bank account on a DTV (only when going through an agent).

You should have said that you withdraw living expenses on a Thai ATM using your foreign credit card. And the 500.000.- THB should have been on a foreign bank account

@Paul ********

exactly. That was the reason. He shouldn't have show them that he already has a Thai bank account, and worse even that he already remitted money onto it. A DTV is a tourist visa class, and you can't even open a bank account on a DTV (only when going through an agent). He can theoretically withdraw living expenses on a Thai ATM using a foreign credit card.

What a question! The Muay Thai schools do not issue DTV visa. For this, you have to apply outside of Thailand on a Thai embassy or consulate. Some still allow personal visits, but most others use the E-visa online system, and post 10 to 15 days processing time

@Jamie ********

that's a steal. I would go for it!

the printout DTV clearly says "valid from" and "valid until". There is no text that says "visa must be used by"

between 7 and 15 days, depending they do not need to ask for more documentation

@Will ***********

you are spot on! This is the most obvious explanation

@Christopher **********

a DTV is a tourist visa type. It is almost impossible to find a bank willing to open an account to somebody on a tourist visa. You will succeed quicker if you go through an agent. It costs 5000.- THB for an agent's service in Pattaya to open a bank account

@James *******

are you really confusing a "visa" with a "stay permit"? You oughta know better
