Women's Organizations and Grad School

I am a full-time college student at a different university and I plan to attend graduate school once I finish my bachelors degree. One location for grad school I am considering is A&M. Regardless of where I end up for grad school, I would like to be part of an organization. So I was just wondering if there were any women's organizations at A&M that would accept graduate students? If any Panhellenic sororities take grad students, those sororities are off-limits to me since I am an initiated member of such a sorority. Any other information on which organizations (if any) at A&M accept grad students would be greatly appreciated
