- there are indeed a lot more of them than before. at the time I was attending, each year we had maybe one student from China. Now they enroll 5-6 every year.
- more rich kids. when i was attending, the chinese students were all attending on a full scholarship from the school (private US education cost being what it was, and Chinese per capita GDP being what it was, few Chinese families could afford it without the scholarship) - these probably explains why they admitted only one student from China per year. but these days, the families don't seem to bat an eye paying the full $40K+/year.
- students are getting more mainstream. in the 90s, applying to colleges from China was like a hack. nobody knew much about anything. to even dream of such things was to be a little quirky. but these days there are all these SAT prep courses and consultants (two of my friends were in this business), and high schools have dedicated advisors on applying to US colleges. and this shows in the students admitted. I remember back then the Chinese students were more creative and original and adventurous (for coming to the US is a risky/adventurous thing to do. selection bias here, not unlike the adventurous 1st generation immigrants coming to the States); these days we get far more over-achieving resume-builders who were president of student clubs, and I think will go on to be investment bankers and have successful careers and I hope will donate back to the school generously one day. Instead of the odd kid who couldn't fit in, and said "f&!k it, I am getting the hell out of here" -- I was such a kid. (I realize this is probably an unfair judgment because I did not have as much interaction with the current students/applicants as I had with people whom I attended school with.)
I am quite ambivalent about the situation. I am happy that my school is getting some attention at this end of the world. but I don't know how I feel about the change in the kind of students we attract and will have as alumni.
