I've used the HHIO (Hua Hin Immigration Office) for 12 years. The office moves to a new location every 2 or 3 years. Proof of address 'fee' to get a driver's license reduced from 1,000 baht to 500 baht, no receipts. New passport 'fee' was 500 baht, no receipt. I know that mean older woman IO. Filling out the forms is simple enough, but I've found the 'contractor' in the motel room out back can do your copies, take photos, and answer questions; making the office visit upstairs on the 2nd floor easy as pie. A couple years back the HHIO manager found a way to align the 90 day with the visa extension. There is a new sheriff in town and that arrangement is out the window.
