Have applied Barry, how soon to hear from them?

Hi,
I have applied Barry U. for the CRNA class in Spring, 2010. I don't know how soon I may hear from them ? because I may need to leave out of States for family reason. Can somebody give me an idea on what time window I will be notified to have interview? someone says it is around Sept. but it sounds too late. Will they contact me via email or snail-mail? Thanks!!!
