I am working on a CPT

2. I am from India. ANy treaty benefits I can claim?

Never heard of it

On F1/OPT you are exempt from residency for 5-years. You must file non-resident tax return Form 1040NR or 1040NR-EZ and Form 8843. Your income is not subject to FICA taxes but you must pay federal and state income taxes. On your income you will get deduction based on tax treaty between the U.S. and your country. Since you are from India, as per tax treaty, you will claim standard deduction of $5,700 instead of itemized deduction. You can also claim exemption for your spouse if she did not have any income in 2009. You can also claim exemptions for dependents.

Thanks... I paid around $7000 for my education. Can I deduct that in Schedule A. If so what line?

No, nonresidents do not get tuition and fee deduction or education credit.
