If I already took out a $20,000 loan, and I would like to take out another $20,000 loan, would it be accepted by a Loan company such as Sallie Mae or Chase? What factors are considered? Are there any other loan companies to take a look at?

I think it really depends on your situation, as well as your families situation if you are still a dependent. Search Google for "Student loans" and a ton of companies will coem up Im sure.

The amount of student loan you can get for living costs varies depending on your circumstances. The loan covers 52 weeks from the first day of the academic year of your course. The amount of loan you can get depends on your family's income.
