The waiting, what is normal for the process?

I reread my letter and I know it sounds like I am being too anxious but they told us how important it was to get the paperwork and CPR done asap as to not hold up the process. Why the was this rush to get everything done? The classes that these same people taught made us believe it would go fast. I am trying to find information online whether it is just this agency or a normal process. Honestly if they said things will be on hold for the holidays I would understand. I understand they are busy, but then why not explain that to us? I just want to help but I have no idea how.
