回複：回複：一些TN辦綠卡的細節請教8老師，

1）我的理解是如果Perm或140沒批，我還可以繼續renewTN, 不會被拒。如果140批了，file了485以後，就不能renewTN了。請問我的理解對不對？

your understand is 100% correct. you can renew TN with Perm approved, but not I140. Once you file I140, you have risk to get TN denied because the I140 shows your immigration intention

-USCIS changed the rule long time ago for TN holder: I-140 filing does not affect the TN status renewal (not counted as immigration intent for TN holder), but I-485 filing does.
