Rushing as a grad student?

[aephi alum]

I know there is at least one NPC sorority, Phi Sigma Sigma, that accepts grad students as members. But how would a grad student go about rushing?

Hypothetical situation: Suzy has just enrolled as a grad student at University X. Phi Sig has a chapter there and Suzy wants to join. There are also a few other sororities.

Does Suzy sign up for formal recruitment, knowing she will be immediately cut from all sororities but Phi Sig because they don't accept grad students? Does she go through informal rush? If formal rush is deferred, does she have to wait until after FR to attend COB events? What if Phi Sig met total and quota and therefore doesn't have informal rush? Does she follow the alum initiation process and then become an active with the chapter at University X?

Also curious about fraternities - I'm not sure if any fraternities accept grad students as new members - but I guess it's a little more straightforward there, during rush you just go to the fraternities that would accept grad students.

Like I said, hypothetical question, but inquiring minds want to know...
