If they are National Panhellenic Conference (NPC) sororities, then no. You must attend their school to be considered for membership. Check out
www.npcwomen.org to learn more about NPC.
If they have local sororities*, contact the locals and ask them. If this isn't a possibility, ask for their assistance in organizaing a chapter of their local at your school.
Also, talk to your student life director to ask him/her about the possibility of Greek Life at your school.
Know that colonizing or starting a sorority, while fulfilling and a wonderful way to develop leadership and team skills (as well as make lifetime friends), is a lot of work and a very big time committment.
* A local sorority is a sorority that exists only at that university; it is not a member of a larger governing conference of sororities and does not have multiple chapters.
