Accepted USF, what is it like?

Hi everyone,
I have been using these forums for a while so I thought I would try them out. I am American but I have lived in Brazil my entire life, so I am considered an international student. I have been accepted by USF and I just wanted to know what it is like there? How is the nightlife, things to do on weekends, etc?
A factor that is worrying me is that I will be living off-campus, because my sister attends USF as well and is currently living in an apartment near the university, so I will live with her. Does anyone think living off-campus will make it harder to make friends?
Also, how is USF for Business? I chose Biology as my major when I applied because my parents are biologists but I’m not so sure about it anymore, I am currently leaning towards Business.

Thank you to anyone who may reply!
