So "Permanent Residency" is based on working here, otherwise it's really a no go? I don't work in Thailand, or anywhere anymore, but today while doing my 8th annual marriage extension, the Immigration Officer was trying to convince my Thai wife that I should switch and apply for "Permanent Residency". Not really sure what it would help or hurt going forward, the marriage extension isn't very hard for us to deal with, we've become experts at getting everything ready fairly quickly and easily.
