I was working for the past year (2010) on OPT for 15 days in Jan and my H1B kicked in for the rest of the year. I have been filing the 1040 NREZ till the past year and do not know which is needed for the year 2010.

Thanks!

If you are married, it is NOT a problem; you will file jointly with your wife and you will both CHOOSE to be treated as resident aliens for all of 2010.

If you are SINGLE, then you have to file a dual-status return, because you have NOT been in resident status for EVERY day of 2010.

If you need professional help filing your return, email me at [email protected] or [email protected].
