University of Illinois Urbana/Champaign vs American University - Political Science

I looked at this option, and it’s hard to tell if it’s only for students from other universities or that plus AU students. Are you saying the students at AU basically have the same program as UIUC in terms of interning?
A naive question, but students can get internships on their own, outside of the univeristy, correct? Like a part-time job in their 3rd or 4th years?
