Hi there,

Here is my situation: my OPT started from May 2006-May 2007. My H1-B started from Oct. 2007. I hired a CPA to file the tax for me in 2006 and 2007 w/ the form 1040. I just talked to my friend and she said in my situation I should file form 1040NR instead. So what should I do now? I already got the tax refund for year 2007.

My friend also mentioned that when I was under OPT my employerand I do not need to pay the medicare and social security tax. She said I can filed the tax return to get the money back. But if I file the wrong form in the first place, can I still get the refund? Can I hire somebody to take care all this for me?

Thank you very much.
I appreciate any help.

If you are single, for 2007 you will file nonresident tax return. Now you will need to file 1040X and properly done nonresident tax return. Read: Your U.S. Tax Return: U.S. Tax Filing Requirements for Non-Residents
