Dittos on both points, MA.
1) Networking in Latin America will be crucial in Amy's career years. According to economic prospectuses I've seen, economic growth in L.A. is expected to be better than that of N.A. in this century. Opportunities should be expanding in L.A. while not so much in N.A.
2) Often university undergraduate studies are basically another high school, just more of it.
Also, BusAd degrees seem to need the additional stamp of an MBA to be attractive to career employers.
Four years at a prestitious U like PUCMM would be a great credit for her, if follwed up by an MBA at a good school in the U.S., even some superior State Schools (e.g., University of North Carolina at Chapel Hill). Furthermore, she will be attractive to the school as a foreign student, even as an American citizen.
Good luck, Amy! Seems like you've got your head on your shoulders.
"a prestigious university like PUCMM"? where is it considered prestigious?
