Well, UChic is changing their course from ‘International Studies’ to ‘Global Studies’, which keeps the required study away, but now it can be in the US (ie, NYC or DC) or abroad. IMO the new module descriptions are pretty woolly, but that may be b/c they are just getting started.
Neither is going to be particularly great for internships- you will be looking at summers, so it doesn’t really matter which you go to: you will get about the same amount of help getting the internships at most of the upper-tier colleges).
Really, for either you will be getting a generic IR major from a name-brand college- neither are where I would pick if I was seriously interested in IR. But, I know that IR is a popular major just now, so your interest may be more general.
Your next step after college will depend more on what you do over the summers than on which college you go to, so pick b/c you like the school not for the program. And those 2 schools are rather different environments
