Internship for summer 2015

I'm looking for a Milwaukee (or in that area) nurse extern position for summer 2015.
It looks like the only applications in that area (Wheaten hospital and Froedtert) are only for student nurses for the spring semester 2015. Does any one know when the summer 2015 applications come out? Also: how many people do they usually take and will they take out of state nursing students? I've been looking near every day for the applications to get posted!
im in the same position, did you ever find out any information about this? i can't find anything and i have been looking since september!
