37 percent of the 2009 graduating class went into the private sector, so I think that even if you don't want to be a diplomat GSFS would still be a good option. Plus, they have the International Commerce and Business concentration as well as the opportunity to cross-register for classes in the business school.
007, I'm surprised that you say that SAIS has a better reputation in Germany than Georgetown does. I would have thought the opposite, but that's good to know since I would like to work in Europe eventually.
If I do decide to go to SAIS I'm going to have to decide soon so that I can start studying for those econ waiver exams... Has anyone heard anything about these/how difficult they are?
