Hi
My stay in US as follows with H1-B

Jul 15, 2006 - Dec 31, 2006
Jan 01, 2007 - Jan 26, 2007
Feb 09, 2007 - Dec 31, 2007

My wife and two kids entered US on Feb 09, 2007 and are living with me.

I would like to know our residency status and which tax form should I fill?

I work (research) with an University and availed tax treaty benefit (article 22) for 2006. How to pay back the tax for 2006 as well as I am planning to stay for the third year?

Many Thanks
Rajan Kombu
