adopting from a rescue revisited

Thanks for all the help with my previous question about who to use as references on my rescue app.  I turned in my application and know that at least on of my references was contacted.  I also know that my landlord has not been contacted yet.  I thought it was a little strange that they would check personal references before checking to see if I can even have a dog.  Anyway my question is, how long should I wait before contacting the rescue about my application?  I sent the app in 2 weeks ago, and my reference was contacted a just under a week ago.  Thanks.
Edit: Never mind.  I just got approved for a dog!  Woohoo!
