Its tough applying from India, no doubt. But you’ve got some excellent marks. Being a topper in anything is an amazing accomplishment. You would undoubtedly fall within one of the top students from all of Punjab, so this puts you in a great position. But note that you’ll still be competing with hundreds, even thousands of students with similar stats/scores from India.
The top colleges accept students from India, but they number that are accepted are fairly small. Since your family income is low, you’ll need nearly a full scholarship to attend college in the US.
So I would suggest to apply as widely as possible. Preferably to colleges that might be willing to give you a scholarship, where your scores are higher than the 75th percentile. There are also some colleges that are looking for diversity (historically black colleges, religious colleges, and smaller liberal arts colleges). I urge you to widen your list considerably.
