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!
