Generally, if you are not a US citizen you are considered a nonresident alien by the IRS unless you meet one of the following criteria:

Green card test:  You are a lawful permanent resident as determined by Immigration, that is, you have been issued a resident alien registration card (“Green Card”) by US Immigration Services, or

Substantial presence test: You are an individual with a valid nonimmigrant visa who resides in the US for a certain required period of time.

The rules are complex in this area.  An exception may apply if you are a student, researcher or teacher or you hold a nonimmigrant Visa.  Refer to IRS Publication 519, US Tax Guide for Aliens, for more information and consult your tax advisor.
