I would recommend both of you consider what type of environment in which you would like to live. State College/Champaign are both effectively college towns. I've never been to Champaign, but State College is basically just the school, housing, and whatever businesses are needed to support it. Especially for an international student, that might not be as comfortable of an environment (but that is for you to decide, not me). It does have more options for $1 pizza slices than any place I've ever been, though. DC on the other hand is a legitimately international city (probably with much better Indian food than a college town), and McDonough is probably the most prestigious school of the three. Personally, I would choose McDonough, but I know for sure that I want to live in a city. You guys just have to consider all pros and cons and personal preferences.
