How to get into top US universities??

I am from India.I finished my 12th this year and am going to pursue a bachelors degree in computer engineering. I would like to pursue my masters in one of the top 10 American universities.
I have 4 years in hand inorder to work in that direction.What qualifications (like GRE TOEFL scores,CGPA, undergrad research orientation,recommendations from professors, paper publications etc) am i supposed to have inorder to study at places like Georgia Tech Cornell UCB Stanford etc...??
I heard that certain top rated US universiotes like Princeton and Caltech take indians who are only from IITs.Does undergrad university really matter to get into places like these?(im not from an IIT)

1. Start researching the top universities you are interested in. Look into their specific admissions requirements and deadlines. Learn about the average GPAs, test scores (GRE, TOEFL, etc.), research experience, and letters of recommendation that they look for in applicants. 2. Work hard to build a strong academic profile. Aim for the highest GPA possible, strive to get good scores on standardized tests, and take part in research projects or internships. 3. Reach out to professors in your field and ask them for letters of recommendation. Make sure to explain why you’d like to attend the specific university.4. Start preparing your application materials early and make sure they meet the requirements of the universities. Pay special attention to your personal statement and essays as this is often what admissions committees look at first.5. Finally, apply to the best-ranked universities that you are interested in, even if you don't think you have a chance of getting accepted. Many universities consider factors other than grades and test scores when making admissions decisions.
