I hope these will be very specific questions

1. I have been on H1B status since 06/13/05 (before that on F-1 & OPT). Do I qualify for Substantial Presence test ? I think yes.
2. If so, do I have to file 1040 or 1040EZ ?
3. Finally, as a single person filing as a resident - do i still qualify for the standard deduction of $3300 and the $5150 under US / India Tax Treaty.

Thank you so much for your response.

1) Yes.

2) For 1040.

3) If you file Form 1040, you are filing as a resident alien and therefore CAN claim both the $5,150 standard deduction and the $3,300 personal exemption.
