Hi,

I came to the US in 2004 as a student. I filed 1040 NR for 2004 and 2005 tax return.

But I filed 1040 for 2006 return while I was still on F1 visa. For 2007, I again filed 1040 jointly (for me and my wife, who came to the US on F2 in Jan 2007 and later changed status to F1, I requested ITIN for her).

Starting Oct 2008 I am on H1b Visa and my wife is still on F1.

My employer will file Green Card for me soon and when I was talking about this with one of my friend, he told me that I filed wrong tax form by filing 1040 instead of 1040 NR for 2006 and 2007.

Will the wrong tax return filing impact my green card processing? Is there a way to correct the mistake I made by filing the wrong form?

Waiting for your suggestions.

Thank you
