It might help if you mentioned some universities you are considering. Most big universities have large numbers of foreign students. Some cities and campuses have quite large percentages of "Asians," both Asian-Americans and foreign students. And while you should try to mix with U.S. students, many colleges and universities have "Asian Students Associations" that provide meeting rooms and activities that might help ease the homesickness and help you with the transition.

Every school is different and each part of the US has a little bit different of a culture. But generally there is nothing to really fit into. There are so many choices in America and that can make it hard to find things in common with other people. It can be hard to meet new people. I recommend you focus on what interests you. Try and stick out a little from your interest. Just message me if you have a more specific question.
