Ussually you can use your regular grants, scholarships, and loans from tuition to pay for your study aborad. I know that you pay regular tuition and that takes off a huge chunk of the travel costs. I myself didn't have a chance to study abroad but I know people who did. It shouldn't be extremely expensive depending on what your university offers. It will be more than regular tuition but I do know that your regualr tuition cost takes off money from the actual cost of travel. Your school should have some kind of program set up like that.
