I think the bigger point is that high school is a bigger influence on how 'assimilated' people are. College is definitely a time of personal growth, but I think high school is even more so a time of growth.

Maybe at 14, your friends aren't locked into FB/WeChat/etc, and the network effect isn't as strong to attract you to one cultural set or another. The other theory I have is that with how much larger colleges are, and in particular how many more international students there are at the collegiate level, there is less pressure to 'assimilate' and find 'American' friends. I've definitely noticed that international students hang out with other internationals a lot in college. It's really common to hear Portugese or Korean in my library, for example. Having some support base probably makes it easier to hang out only with those who are super similar to you.
