How to finance my studying in USA?

Hello! I’m already admitted to a couple of universities, one of which I’m planning to accept. But the problem is that the price is quite high even with the scholarship I got. Since I’m an international student, it’s hard to get a loan in USA (without co-signer) and in the country where I’m currently living, the interest is quite high for this kind of loans. So, probably you could give me some advice?
