Welcome to Portia's Secret Garden in USA-Pixnet

Today, i got my paycheck and i figured out i was withholding for social security and Medicare tax...
I went to payroll to argue with director and he just claimed that because I am a graduate student, i need to take the tax off my paycheck.
I can not argue with him, so I called IRS to verify my status... yeh..
after holding for more than 15 min, and discuss my problem for around 20 min...
Wowwwwwwww.............................
I am a nonresident alien student which entitled to exempt social security taxes...
give me my money back!
