Went yesterday to Khon Kaen Immigration. Got my 60 days Extension of Stay based on being married to a Thai National. It was the last day in their office due to relocating to new office in building 2 of the bus terminal 3 in Khon Kean.
Without a queue ticket machine, but old fashioned numbers on plastic, lots of boxes with personal files all over the floor, just 4 desks with staff it went quit smoothly. Had to change only twice from computer system, because the scans did not work as supposed to. They were moving out while still doing there best to help all those who visit during this moving.
Next visit will be in their new office.
