I'm not exactly sure how the affiliation process works for local sororities going national, BUT I just wanted to say that I'm really happy you all are interested in Delta Zeta!!

It's a great organization (in my own rather biased opinion

). I wish you all the best of luck!
The pledging process is a maximum 8 weeks long, which I'm pretty sure is the same in all chapters. I'm not sure what kind of adversity you're talking about, but if you have any more specific questions I'm sure that myself or anyone else on this board can (or will try!) to help you out.
