Studying in germany and then coming back to the US?

Hey everyone! I'm going to be a college freshmen this year. I will be doing at least one year of college in the US, I am going to Rhodes College. However, it is rather expensive for me (even with scholarships, I need to take out about $20,000 in loans per year). That amounts seems like it will haunt me and I don't think it's a good idea to take out that much. However, I've taken german in highschool and I have a few friends who live in germany. This has made me think about going to germany to study in college. My list of possible colleges has LMU Munich, TU Berlin, and ETH Zurich(switzerland). I'm actually set to go there after taking some intensive german courses for the next year, except for a few issues I'm having.



First, say I did a bachelors in physics in Germany and then decided I wanted to come back to the US for graduate studies. Would my prospects of getting into grad school here with scholarship/internship be hurt if I were to study and do research in germany as opposed to studying and doing research in the US?



Secondly, if I were to do my complete bachelors And graduate studies in germany, and wanted to come work as a teacher or a researcher in the US, what would my prospects be? Would I have extra difficulty finding a job or degree recognition in the US, coming with a german degree? An example of a place I think I'd like working at is Oak Ridge Labs, in TN. If anyone has any insights on this type of thing, I'd love to know more. Thanks!
