Monday, I went to Pattaya immigration to get an extension, I was done in 30 minutes. I showed up at/about 9:00AM, nobody was in line. I had almost all of my correct paperwork, I needed a photo copy of my TM30, which they allowed me to go make a copy and come back to the same counter (by that time a few more people came so there was a little line). I got my queue number and waited about 5-10 minutes, I gave the IO my paperwork and about 5-10 minutes later they return my passport.
I am not sure what happened but Pattaya Immigration has changed quite a bit over the pass couple of years. Not only have they done building renovations but "customer service" seems to have been renovated. The last time I did an extension myself, I went to immigration 3 times/days and finally was told I would have to come back on the last day of my visa, I finally paid an agent and got the extension same-day. 3 days + 4000 baht for extension two years ago vs 30 minutes + 1900 for an extension today...
Well Done Pattaya Immigration - THANK YOU
Also noteworthy, I have a long questionable visa history and a new passport, not sure if the new passport helped or not.
