It won’t help you at all. In fact, it will hurt your chances. Highly selective US schools do seek geographic diversity from within the US (like coming from Wyoming if you’re applying to very selective schools in the Northeast), but they are not seeking out students from Peru. That being said, if you are demonstrably one of the top students in all of Peru, top schools in the US might be interested in you.
I’m assuming that you would need financial aid. There are a lot of threads on this website about international students seeking scholarships, and which schools might offer this to them.
If you are a US citizen, or US permanent resident, then yes, you would look kind of interesting to top US schools. They can offer you financial aid just the same as if you were in the US, and your having gone to school in Peru would bring diversity to the class. But if you are not, then you would have to be an extraordinarily high achiever, one of the top students in all of Peru, to have a chance at a top school here, and only a few schools would offer you financial aid.
