Hi

I came to US (from India) on a F-1 Visa on Dec. 23, 2005.
I am currently on OPT which started in Aug. 2010.

The questions I have are :
1) Is this my 5th year or 6th year as a F1 student?
2) What form do I use for federal return 1040 or 1040NR?
3) Currently my employer is with holding FICA (medicare and SSN), (from Aug. 2010). Am I eligible to ask for a refund for 2010 taxes?

Thanks a lot,
Raoul

You are in your 6th year in 2010 (it goes by calendar years), so you are a resident alien for 2010 and are subject to social security and medicare taxes. As a resident alien you file form 1040 (or 1040A, 1040EZ)

Thanks for the quick reply. That was helpful.
