Starting an NPC Sorority at a Campus with No NPC Presence

[HelpPlease]

This is not just another post about starting a sorority!

I have started researching and I am well aware of the time and commitment needed to start an NPC sorority. After seeing the detailed steps for expansion on the NPC website, I still have questions because my university does not currently have any NPC sororities.

Currently, there are only 2 sororities (both national), 1 national fraternity, and 2 national fraternity colonies. Greek life is still fairly new and there is no Panhellenic or formal 'Greek Council'.

How would I receive approval for expansion if there is no Panhellenic? Has anybody been in a similar situation before? For those who have started an NPC sorority, how long did it take to become a chapter?

Any advice or general help is very appreciated! I'd love to hear your experiences!
