If you could get Honors college at South Carolina in your budget that’d be a great option. Their honors program has a lot of bells and whistles and their international business program is esp. well regarded. (SC has a ton of foreign investment, especially German companies.) It’s also a beautiful campus in a nice small city.
Run the NPC for UNC too – bigger reach but they are a top business school and meet full need aid even for OOS (unlike UMich or the UCs).
