Koh Samui VISA payments. Each year the payment for a retirement Visa ( multiple Non-Imm ) varies between 6000 and 8000 Baht with no issue of a receipt. So for my wife and I it’s double that, 12000 to 16000 Baht, with no receipt. Does each immigration office have their own fee structure? On line the reported fee is 1900 Baht each. I would welcome any comments from Retired persons using the Samui office. Thank you.
