I want to join a sorority, I need help!?

I am a rising junior at a small women's college that does not offer greek life. I want to join Alpha Kappa Alpha Sorority, Inc. I looked online to find out ways to join a graduate chapter or if there are ways to join while attending a different college/university, but the rules where not clear. Can some one give me advice? This is something that I really want to do and I'm willing to do whatever it takes.
