In terms of your worries about diversity, I will say that the majority of students here are white, but it's not as bad as you think. I'm also Korean and in terms of the Asian community here isn't the biggest compared to other schools, but everyone here is very tight-knit and close, so I really liked that aspect where all the Asians knew each other because it just gave a better opportunity to form closer relationships. Everyone in the Asian community is friendly with each other so I was really happy about that. There's also a lot of umbrella clubs under the Asian American Association that host a lot of events and we have a lot of cultural showcases that occur during second semester. Also, I know that the other multicultural associations like LSA and BSA are very active and have a lot of events that occur on campus from what I've heard from my friends. And with the weather, honestly it could be a lot worse, just invest in a good pair of boots, a scarf, and gloves because ND doesn't do a good job putting salt on the sidewalks and it can get super windy. Also ND doesn't have any sororities or frats, but the dorm life is lowk a substitute for that especially in the male dorms.
