Dear Kishore,
I will urge you to check stemdegreelist.com for STEM related subjects. Whatever you want to study, it depends on your choice, match the course along with your career interest.

You can apply but hardly anyone from India gets accepted there.
You have to be a straight A student with more than 95% in +2 with a SAT score of 1550+ and a perfect subject test score. Maybe then, you have a 60% chance.

You need to score a minimum of 6 marks & at least have 1 to 3 years of experience to get into private colleges. In GMAT, a minimum score of 500 is required.
