Hello, Just wondering if anybody knows how far in advance I can go to the Immigration Office in Koh Samui in order to extend my Retirement Visa. My current extension expires on December 27. I just found out today that there will be a Maroon 5 concert in Bangkok on December 10, and I'm thinking about going........so, I would feel more at ease if I could take care of Immigration prior to going up to Bangkok on Dec 10. Probably something I should call the Koh Samui Immigration Office about, but it's the weekend right now. Thank You.
