Chicago

Hello Rashmi, it's very nice to hear your ambition of doing MS in Computer sciences from the university of Illinois Chicago. Be advised that institutions abroad including in USA do not base their admissions exclusively on academics at the level of graduation but it's a combination of different aspects of the personality of the would be student. There are many aspects which they look into before giving admission. In view of this I would strongly recommend you to approach an agency which is dealing with sending students to USA for MS since they would be knowing as two different aspects that a student must fulfill to make a successful application. Best wishes to you.

The eligibility required is:
1. UG
Almost all US universities require 16 years of education. That is four years of education after high school/junior college.
If you have a three-year degree from an Australian, Indian, New Zealand university or such similar three-year degree programmes, you will not be eligible for admission in most of the MBA programmes. You would require a professional four-year degree like engineering or any other course.
If you have completed a three-year degree program like B.Sc, BA or B.Com from an Australian, Indian, Pakistan, Bangladesh, New Zealand, Sri Lankan university the advisable plan of action to maximize the eligibility for US business schools is to do a postgraduate degree like M.Sc, MA or M.Com, before applying to any of the business schools in the USA.
A one-year university affiliated program will make up for the fourth year required. The key point is to ensure that the program that you do is a recognised university program.
2. WORK EXPERIENCE
Most of the US universities recommend/require a minimum of two to three years of work experience. Though some universities may accept you without any work experience, preference will be given to the candidates with work experience.
3. GMAT
GMAT is required for almost all the universities in the US. It is also one of the most important criteria for admissions. If you are planning to study in a US business school, you must score high in this exam. For more information on GMAT, check out about GMAT.
4. TOEFL
This is required by almost all the universities in the US. It is a fairly simple exam for most of the students who have studied in the English medium school. The minimum score required for most universities range from 550 to 600 in the paper based TOEFL and 213 to 250 in the computer-based TOEFL.
