International students in Ann Arbor must be struggling and having a hard time.  The people in Ann Arbor are friendly but it is not easy to approach them and ask to be friends without being seen as "weird."  They international students have to learn the culture and the social norms of Ann Arbor to adjust to the environment.  If they cannot adapt to the culture and the environment, then the students will feel lonely and isolated.  Their adjustment process will also be complicated if they speak English with an accent.  Many Americans distant themselves away from people who speak English with an accent because they are not used to hearing the language that way or that they think they cannot understand the individuals.  The distance or the alienation will further depress the students and make them miss home more.

Even though I am abroad in a foreign land, my experience is not the same as international students.  Many people in Korea speak English and it seems that they like Americans (even the ones that look Asian like me).
