Mount Holyoke has like a ridiculous number of international students-- like 500-600, with a student body only 4 times that size. Internationals usually amount to 10% of most schools that offer financial aid to them.
‘(dress a certain way, like certain music, have a certain set of ideas etc)’
Okay, at least at my school, nobody cares how you dress, but for instance at my friend’s school, Middlebury, it is a norm to dress ‘well’. Schools like Vassar and Oberlin are more similar to mine, where you would not have to dress to please others.
Like certain music? From experience, you can keep your music taste private, and the people who criticize your music will clearly be pretentious hipsters who have never studied music or play an instrument (those who have, on the other hand, willingly listen to the Lizzie McGuire soundtrack with you).
Have a certain set of ideas: Well, most LACs tend to have a very liberal student body. The key is to find an open-minded student body. When I visited Scripps and Pitzer, I found the students very much to my liking in that they were willing to change their views after debating on contentious issues. My friends at Mount Holyoke, on the other hand, have become scarily liberal, almost indoctrinating others into accepting their views, and cursing at those who don’t (there are cases at MHC where not-so-liberal students received death threats). Now I don’t know if this is the pervasive attitude on the campus, and it’s probably not? I can’t say. I don’t go there. While you would probably always be able to find a group of friends at most schools, it is not difficult to be alienated by most of the community if you try to defend the use of the n-word by a white person or something similarly stupid, especially at schools with smaller student bodies.
I come from a very liberal background, so I faced no culture shock or difficulty in finding friends, but that is not the case for all internationals. Wherever you go, just go with an open mind.
