Ok, a guy from a college asked me a question about tax and I was unsure. Here it is:

1. What are the benefits of filing taxes as a non-resident vs. resident? I told him that you get higher deductions as a  resident alien but you will have to pay social security and medicare taxes. But, how much benefit can someone going to a college can get from that?
2. How much can they benefit by claiming to be non-residents in OPT period? I guess they will save more during this period by claiming to be non-residents?
3. What are the standard deductions these college kids can take this year?

Thx.
