Best answer I've got would be to
look through list list of teams in the US--the find function on your computer should help you find may of them (but not all; to find that 190's partnered with WPI for example, you'd have to be looking for WPI).
On the flip side, I worked with teams all through college and none were officially connected to USC. (Only after I graduated did 2815 start up on campus.) You may want to look up local teams near schools you're looking at; surely at least some of them would welcome your help if you choose to work with a team (standard don't-flunk-out warnings noted).
