I would at least look at the 1040NR at
http://www.irs.ustreas.gov/. Also the instructions for itemizing deductions. The one thing right about our insane income tax system is the relatively high standard deduction. For many people, the standard deduction is high enough that they are better off taking the standard deduction than itemizing. You are allowed to take which ever means the LOWER taxes. Go through the big things, state and local income tax, real estate taxes and interest if you own real estate, medical expenses, etc. You may also be able to deduct any taxes you have to pay to India. If you aren't close or above the standard deduction from a few bigger items, you would be better off forgetting it and filling the 1040NR EZ. If you have to fill out half the 1040 to decide if you you want to itemize, go ahead and finish it. I have filed it and taken the standard deduction for years. The forms are much the same except the long form has more options.
