U r in OPT so u qualify for 1040 as a resident.

Also, use the education credit if ur 1098T says u have paid around 10000 mark. The deduction means more u spent on education more u save but the education credit gives u upto 2000, i.e. 20% of 10000 total education expense. However, don't forget to fill education credit form with your return claiming hope credit rather than deduction.

To make it short and sweet. goodluck!!!
