Often, fraternity chapters are formed by groups which choose a national organization they aspire to join. Those groups can form an "interest group." They'll need to probably contact the organization they're interested in joining first to see what the criteria are, whether the national is interested in colonizing at that particular university, etc.

Also, just a small word of advice. When you contact a national organization, you're going to want to sound very professional. Any allusions to the fact that you "like to have fun" should definitely be left out. We all know that fraternities like to have fun. It's just that the national is probably going to be expecting you to be trying to spread their organization to a new campus because you support that organization's ideals, not because you want to hang up some well-known letters at your next party.

We build our national reputation (ideally) for things like brotherhood, success, friendship, and alumni support not for our great parties (nothing says you can't be good at all of the above).

Good luck.
