Possible to go from TN status to permanent resident?

It is possible but there is a potential consideration of conflict of intent. Talk to an imm. atty at a href="http://www.myfianceevisa.com" rel="nofollow"http://www.myfianceevisa.com/a or do more research on the internet. TN only allows temporary intent which conflicts with applying for a green card. But changes in plans do happen which the CIS acknowledges. there are timing issues that an atty needs to examine (e.g., when youc ame in, when you got married, how long you knew each other). good luck.
