Dear Aspirant,

As you have scored good in GRE and your IELTS score is also decent but only this won't help you to take admission in MS in United States. The universities look for research experiences, Letter of recommendation, relevant certificates and students participation in extra curricular activities. In terms of CGPA which the student has to convert into GPA and roughly it should be near 7.5 CGPA  which will confirm your admission in MS after securing such marks in GRE and IELTS. Still you can get admission if you have done some extra-ordinary work in Research area and publishes good amount of research papers.

Hope this information is helpful.
Have a great day!
