International students aren’t always people of color. My daughter’s school was 1/3 international, but many were from Sweden and England.
I asked my daughter if she interacted or studied much with international students. She didn’t. She said the language barrier is too hard, especially if you are on a deadline to get a project done. Socializing, she mostly stuck with teammates. She is Chinese but doesn’t speak Mandarin and most of the Asian internationals were Taiwanese and she doesn’t speak that either.
Other daughter happened to be on an international floor in her dorm. Very little interaction and that daughter is very friendly. Don’t expect a big melting pot.
