Indoor compressor air conditioning systems do exist where local laws may prohibit adding them to the external building areas? I have never seen them in Thailand. The heat generated still needs to go via insulated ducting to the outside some way or other. Maybe the op never noticed the ducting?
How does someone lie and conceal information making an ATM withdrawal using a foreign bank card? These are not remittances. Remittances are when funds are deposited into Thai bank accounts. In general, using a foreign bank ATM card to withdraw cash locally is not considered a foreign remittance transaction, and therefore may not be subject to taxation.
Asking for a friend, but I understood one often cannot open a Thai bank account without a Non Imm O visa, and one cannot get a Non Imm O visa with funds in a Thai bank account? How are folks getting around this?
