Haas is one the top business schools in the US. It’s at Berkeley. They have MBA and undergrad. Huge recruiting goes on from top firms who swarm to the haas students.
Way higher reputation than global studies or intl studies. Not saying the others aren’t great, but Haas is Haas. They would LOVE you! Plus they like int’l students.
