Hi,

I was on F1 from 2004-2009.
During 2010, I was on F1-OPT from Jan-Sept then my status has changed to H1B.
Do I file 1040A or 1040NR?
Also, am I eligible to get refund for SS/Med taxes that were deducted when I was on F1-OPT?

Thanks,
Polly

Polly:

You became a resident alien effective on 1 January 2009, and, on that date, you also became liable for FICA (Social Security and Medicare) taxes.

For 2010, file Form 1040A.
