Local sorority "seeking national affiliation"

[klplovely]

Hey everyone! I'm new to GC and as I've been reading some posts, I've seen "locals seeking national affiliation" mentioned a few times, and I have a few questions about it if anyone knows.

How does local-national affiliation work? Would the local organization have to change their letters, or would they be seen under the national organizations wing? In other words, would the local have to give up their letters in order to become a new chapter of the national organization?

Any answers are appreciated =)
