Does this mean you already have scholarships?
Or does it mean that you are requiring scholarships?
If you require funding, you need to know that you have less than 1% chance of admission. You are over-represented as a student from India. Also, the universities lost a lot of money over the pandemic, so their coffers and funding have tightened.
Targeting the Ivy leagues for admission, makes your chances even slimmer. Too many students and not enough seats. Plus, every Ivy is vastly different in everything-location, size, program, and “environment”. The schools decide who they want and it has a lot to do with fit. You have to be something to fit a need such that you have to “fit” the entering class. Maybe they need an oboist/cello, painter, gymnast, etc.
If you are already funded then you need to target schools that are within your scholarship budget, if that is your goal. Schools need and will take your money.
Edited to add: If you gain admission to a US university, you are expected to return to your country after graduation. Your visa covers you as a student. Once you are done, you return home. Your major is: Government, specialized concentration, economics. Is there a job, available in this major, when you return?
