My son had very similar criteria (stats, small budget, and wanting to study German including abroad), but was looking for engineering. We found this E3 program to be quite intriguing. There are several US and German institutions that participate. While it’s engineering-focused, I noticed that they do some other disciplines as well. There might be enough overlap between management and supply chain with industrial engineering that this could be a helpful resource.
