I was in US for 2 years and life sucks there. Kids/kallus and mexicans treat Indians very badly. The policy do not support us. We had to live with fear all the time. If you travel by a suburban bus or train in cities like Chicago and Boston you will come to know the risk. Kallus openly roam with guns and knives and ask money from Indian.
My advice to students is to be careful while selecting the cities for study.
