It is written on the admission letter if a scholarship is awarded. Scholarships seem to be awarded only to students who are in top 1% in their country and only from the best high schools of their country.
UIC does heavy recruiting and marketing trips in SE Asia and is very attractive college among SE Asian students. Most of the admission scholarships go to SE Asians. The best Western students decide to study in America or Europe and therefore there are not many Westerners with an admission scholarship.
