This pertains to Ubon Ratchanthani, just did my 1 year extension for Thai child and there have been a couple changes in the process. My wife had to fill out an affidavit, we had to get a friend or a relative to give a copy of their ID card and house book. Plus they were very specific about the photos, bedroom, kitchen, TV room, by front door of house, next to house number and a complete view of front of house. We had to retake the house number photo so it was straight on( could not be at an angle) and they wanted a wider view of front of house.
