To get a scholarship you need to have good academic results in your Class 10 and 12 if you are applying as an undergraduate. If you are applying for Masters, you need a 4 year degree completed with good results. Also, SAT and TOEFL scores are important for undergrads and GRE for graduates. If you have good scores in all this, you stand a chance of getting a scholarship.
Also, most public universities dont give scholarships to International students. Private universities do but their fees might be higher than public schools.
