Manish - what are your plans for gap year? How much can your parents afford per year? This will make a big determination on what type of schools to apply for.
In the US, there are only a handful of colleges which are need-blind for internationals. The rest are need-aware, which means they take the level of your need into account. Since college financial aid budgets are tight, they tend to take internationals with amazing credentials. To balance this out, they will take lots of internationals who are full-pay.
