問題是我拿H1B來美，從第1年就用1040EZ報稅，從來沒用過1040NR，我的W9上麵也寫我是以resident alien來報稅的，我一直claim tax treaty一點沒有問題。
-You should use 1040NR for the first three years after you entered US. But it does not hurt you if you filed 1040EZ and claimed the US-China Treaty benefit because you were qualified for that during that time.

我有了綠卡以後，報稅身份一點沒變，同樣可以填1040EZ，所以不知道很多人說，綠卡以後要被征稅依據是什麽？
-Now, your status has been changed to LPR, not qualified for that benefit anymore. That is the difference. If you still claim that benefit, you will be trouble whether it is from IRS or USCIS.
