Congratulations on your great acceptances! My daughter graduated from Kenyon last year, and she loved it. I understand that it’s not known in China, but this is quite typical: US liberal arts colleges are not well known internationally (and most of them are only known in certain circles or regions in the US). I’ll say, though, that the education our daughter received at Kenyon was top-notch. My husband and I are both professors at a reputable research university with Ph.Ds from an Ivy, and we were very impressed with both the rigor and the level of individual attention at Kenyon.
It’s hard to predict how things will develop politically anywhere in the US right now. Ohio is leaning conservative, but the college itself is very liberal and accepting. There are definitely Asian/Asian-American students there, but I’m not sure what the proportion is.
Of course, your other options have a better name recognition (although Kenyon is well-known for its English, theater and creative writing programs), but since you seem to like Kenyon and it’s so much cheaper, it’s a great option, imo. Their campus is gorgeous, by the way, although be aware that it’s rural, unlike your other options (although Columbus is just under an hour away by car).
Feel free to send me a message if you have more questions.
