Fwiw 10 years ago I was organizing weekly dance parties in a college town. 80% of our attendance was foreign students. Nightly I would have kids from all over the world profusiosly thanking me. The bulk of the complements were in one way another "thank you so much for putting this on I feel like I'm home. I don't get American culture but I get this." 10 years later I still have people coming up to me randomly thanking me saying they've stuck around because of friends they made.
In my limited experience I feel there's a real cultural mis-match with kids from other countries coming here to study. Most of the kids I met were from huge cities and the shock of being in a small college town was in many was too much for them. That and the greek system was overtly hostile to them.
On side a note it's humorous what many kids take back with them from their time in America. It's worth doing an image search of "American party" to see what I mean.
