transfer using WISE from your home country bank account into your Thai Bank account after you get your pension, it is straight forward. You get a fairly decent exchange rate with WISE.
Do it the same day or day after your Pension lands in your bank account in your home country, using the Wise App, just make sure it is a little bit more than 65,000 baht so your account will never be under for each month in your Thai bank account, slowly building a buffer in case of any unforeseen fees or such that the bank may deduct sending your deposit under 65,000.
housekeepers and managers assistance are a dime a dozen, you won’t be getting a work permit visa in that field of operation, back to the drawing board.
