Beta Sigma Phi is a social sorority. It's a non-academic sorority, which means chapters are not required to be affiliated with colleges or universities (although there are several chapters that have elected to become student organizations and/or part of Panhel). Because Beta is non-academic, women of all ages and educational levels may be invited to join. There is no alumna status.
The International website is really thorough, and I encourage you to check it out! I'm so proud of my sorority!
