if you are going to file for refund of social security and medicare taxes...which you should get since you are on OPT...you have to do the 1040NR form...too bad you won't be able to use the standard deduction or get tuition credit, so I would recommend you try both at first...if the NR return and SS refund amounts to more than the regualar 1040, go for that...otherwise just do the regular 1040.
