Join IU fraternity as IU-PUI student?

I know the chance is low but since I’m still consider to be in the same system as IU-Bloomington. Is it possible for me as a IUPUI student to join the frat at IUB for the opportunity of network, I know a few member in the frat would this help? Or do I have to be a IUB student to join their fraternity?

Thank you
