Definitely get out of the US, for a change. Where you go doesn't matter so much, but good choices for you would be netherlands, belgium, canada, spain, and new zealand. Choose your career, then pick a university in one of those countries that suits your industry. Antwerp, Belgium would be a good choice because it only takes 3 years to get Belgian citizenship (which is compatible with US citizenship), and you're just ~30-60 min train trip from NL.
Avoid Australia - it's as conservative as the US. Avoid South Africa - they're not over the racial issues there, and the separation between the lower and upper classes is huge (exacerbating the racial tensions).
