求教税法

小弟99年持F1来美，03年持OPT转做博士后，H1B正在申请中。但从04年一月，学校以我来美已the sixth calendar year ，已是 RESIDENT ALIEN 为由不再给我 TAX TREATY，
且开始扣我SOCIALSECURITY 和MEDICARE。

1。在我并没有申请绿卡的情况下，说我是RESIDENT ALIEN 对吗？我仍是F1，扣我SOCIALSECURITY 和MEDICARE对么？那我明年该填什么税表？是否还可以找回这些MONEY？


2。有些博士后做为RESEARCHER是不用交FEDERALTAX的。

US-CHINA tax treaty article 19 says,

An individual who is, or immediately before visiting a Contracting State(US) was, a resident of the other Contracting State (China) and is temporarily
present in the first-mentioned Contracting State for the primary purpose of teaching, giving lectures or conducting research at a university, college,
school or other accredited educational institution or scientific research institution in the first mentioned Contracting State shall be exempt from
tax in the first mentioned Constracting State for a period not exceeding three years in the aggregate in respect of remuneration for such teaching,
lectures or research.

请问我的情况适合该条款吗？

谢谢
