Foreign Language Programs?

I’m a current sophomore who’s really interested in foreign languages (specifically Mandarin as that’s what I’m taking in school). I already have plans for next summer, but are there any good foreign language programs I could take afterward (I’d be a rising senior)? I already know about Middlebury and Concordia’s, but I was wondering if there were any other U.S.-located options I should take a look at. Thanks!
