Nice sig, Valoise.
I think it would be neat to be international and it would definitely rule for road trips, but I think when people are looking at statistics as "selling points", they look more at number of chapters than international presence. I know D Phi E is one of the "smaller" sororities but they are international, as they have several chapters in Canada.
Heck, there are some orgs that are (mainly) stuck in one area of the US and it would be a major coup if they got a chapter in the West or Northeast, let alone Canada.
