I am graduating in May 2014 but also am eligible for a externship/internship. I looked into mayo clinic, they have the application open now. It offers very good xpience(I have heard) and is a great program, they offer good pay, excellent skills opportunities, and housing if needed. I think you should check into your local hospitals too and see if they have any opportunities. I know that there are some in my area but I am on the opposite side of the country and they recommend that you would work some hours during the school year so that they will be able to hire you when you graduated I haven't really found any more opportunities though.
