I have no idea...as I mentioned. phot office but they had all sorts of visual aids there to help visa applicants. Maybe it was just a non-related office that gets most of their business from immigrations. In my case, when the immigration officers pointed, directed or instructed me, along with other applicants to go to these certian places to get our paperwork, we just did it and those offices helped us/our paperwork to be processed. I asked others who said they had been living in Thailand for many years, while going through this process, about everything from what the name of these other offices were...the process...to get some sort of cllarity. Almost everyone said the same thing...it doesn't get easier, they are confused each time and advised I just roll with the punches. I'm going to continue to try and figure things out. Thx for your question.
