Hi

I was on F1 status from Jan-2006 to May-2006 and had no income. From June-2006 to current I am on OPT status. I worked from August-2006 to December-2006 on OPT status.
Which TAX return form I have to submit? 1040 or 1040 NR or I have to submit 1040 and 1040NR separately.

Thank

Form 1040NR or 1040NR-EZ. You are STILL a non-resident alien under an F-1 visa.

However, the rules change if you came into the U.S. prior to 2002.
