First of all thanks for all your posts they are very useful

Have a few questions. I am an Indian who came to the US on F1 Visa in 2003 graduated in May 2005 and have been working since Oct 2005 on H1B Visa. Last year I filed 1040NR. Here are the questions:

1. Since in 2006 I was on H1B for the full year do I file as a resident i.e.. Use Form 1040?
2. I am married and my wife is on H4. She has her ITIN number. Do I file as "married filing together"?
3. As a student I would get a deduciton of $5000 under the India Tax Treaty Article 12 or 21. On my H1B do I still get the benefit of this $5000 deduction?
4. I have a student loan. Can I claim deduction on interest paid towards student loan?
5. If I file "married filing together" does my wife still have to sned in a separate Form W7.

Thanks
AJ
