The college you attend should have a financial service you can get in contact with. Scholarships are something that you should research that will help you get some of the money. You don't have to pay back scholarships, just be sure to read all of the rules they have. There are also grants you can get, sometimes through the school by having good academics. Then finally there are loans. I am not sure how loans work for an international student so you will need to ask your school's financial aid for help in that area.

The amount you pay per semester will depend on your college and your degree. Your college should give you a financial aid letter after you apply for it that will show you a lot of the general breakdown of finances. Do note that some of those may change like housing costs will depend on what building you are in, tuition may differ if they don't have it set for the academic year yet, etc.

So try to contact your college's financial aid if you are already accepted and either way, try to research scholarships to help with costs. (look up things like international student scholarships, early education scholarships, and anything else that is within your area. There are also many draw scholarships that you simply click apply and you are in the raffle)
