I was just wondering if the sororities at USC are open minded about girls from other parts of the country?

For instance, I am from New England and I am thinking about applying to schools that seem to have a good greek life. But, what if I don't get accepted into a sorority?

I have average grades, have played sports and been involved in a few ECs, I know how to party, I am very social, am about 5 foot five, thin, with brown hair, and I have OK looks.
What kind of social life would be available if I rushed but didn't get a bid?
Thank you for your help!
