I am on F1 visa OPT, my H1 got approved since Oct 2008 but still I am working on OPT, as I need to get the stamping at the specified US consulate before I can enter the country back on H1.

I am in the United States on F1 visa till now for these many days:
2006 – 158days
2007 – 365days
2008 – 366days

I have the following questions:
1) Do I need to file 1040 or 1040NR-EZ?
2) I have relocation expenses of $3500 reimbursed by my company and mentioned in W2, I will work at the present location for more than 38 months; can I claim this as exemption on either of the above forms?
3) Since I am on OPT (student visa) from India can I claim any other exempts under special treaty? (apart from $5450 (line 11 of 1040NR-EZ) and $3500 (line 13) )

1. If you are single, you file 1040NR-EZ.
2. Yes, you can claim moving expenses. Read: Your U.S. Tax Return: Moving Expenses (http://taxipay.blogspot.com/2008/02/moving-expenses.html)
3. No, except moving expenses, student loan interest.
