To cut a very long story short, in Feb./Mar. this year I went to an agent in Bangkok and changed to a retirement visa. However, unbeknownst to me until after the visa was issued, they went to TRANG to get it there (long story). Now, I need a Certificate of Residence and this is obviously going to open a whole can of worms as I don't actually live in Trang. So, I am wondering is it possible to change my "address" from Trang to let's say Bangkok or Nakhon Ratchasima, where I actually live? IF yes, then HOW do I do this? Could I then do the extension in BKK or NR next year, or can it only be extended in Trang?
Also, IF I were to leave the country, would that automatically cancel the retirement visa?
Thank you.
