Do you know which forms do I have to fill for my 2008 Tax Return? I live in MA and I work under my OPT since May 2008.

Thanks in advance.

Form 1040NR or 1040NR-EZ and the part-year return for Massachusetts.

If you did not complete 5 years on F1, then you will file Form 1040NR or 1040NR-EZ and 8843. You will get treaty deduction. Read: Your U.S. Tax Return: U.S. Tax Filing Requirements for Non-Residents (http://taxipay.blogspot.com/2008/03/us-tax-filing-requirements-for-non.html)
