Is there any international student playing poker online in US?

[892King]

Hi, I am an upcoming freshman of CMU and I've played poker on FTP and PS reguarly.
And I heard US gov.(IRS) is really SOB who try really hard to rob US player's BR under the name of TAX.
Actually, gambling(includes online gambling) is illegal in my country and I didn't pay any taxes in the course of nature.
So I wonder if there is any international student(don't have greencard of course) who withdraws his income to his US account via bankwire transfer regularly.
And if so, I wonder if u pay any taxes to IRS or something.
and plz lemme know if u know any laws regarding this case although you are not an international poker playing student.
