You are clearly unfamiliar with the area. You won't be going out to bars in Downers Grove, it's a small suburb. If you are going to be going out to party, you will be going to downtown Chicago, which is one of the most diverse places in the country, or possibly Naperville. I can only speak for myself, but as a minority, I have never felt uncomfortable in Downers Grove or its surrounding suburbs (Lombard, Oak Brook, Naperville, etc.), as they all have extremely large asian/indian communities. Naperville for example is 15.65% Asian and Oak Brook is 20.11%. Lombard which is literally TWO MINUTES away from CCOM is 8.70% African-American. Also, in Chicago I doubt you will be getting "stares" or "smart ass remarks". I live 5 minutes away from CCOM, and have a lot of experience with the area.
