I do see your point, but I’ve been here a long time and never yet made that mistake. If anyone does feel the need for an ‘insurance policy’ they only have to buy a single entry permit, for 1000 baht, when they renew their extension. No need to buy a multiple entry permit. Each to their own.
Ridiculous. If you’re only going to leave the country once in the year why on earth would you buy a multiple re-entry permit? Buy a single for 1000 baht and save yourself 2800 baht. If you need one on the hurry up you can get it at the airport if your local immigration office is closed, at the weekend, for example.
Your third paragraph was the answer the OP was asking for. Not sure why you jumped down his throat with the other two paragraphs. I don’t feel his question deserved such a rude response.
No. It needs to be shown coming to your account from overseas. If you transfer it to your partner, then they transfer it to you, that is an internal transfer, so does not fit the requirements.
