IELTS

I have heard of the universities like MIT, Berkeley and Princeton.

IELTS or TOEFL either works. GRE will depend on the university under consideration.

In addition to this, students need to appear for IELTS or TOEFL to prove their efficiency in the language. For PG courses: Students are expected to have at least 70-75% from a reputed Indian university. They are also required to appear for GRE (by some universities) and a score of above 300 should do the needful.

Dear Rishabh,
Recently, I have come across a brilliant opportunity which I heard through a close relative of mine. JK Lakshmipat University situated in Jaipur is offering a very interesting programme that gives you an excellent opportunity to do MS at JKLU for one year. It also comes with 3 years of OPT in STEM. There are a number of courses that you can choose from and also have a 50% scholarship. Most of all you don't have to give any competitive exam for doing MS in the US like TOEFL and GRE.
