Just because most US colleges are need aware (they take financial need into consideration when deciding whether to accept a student), that does not mean that you should not try. You have a guaranteed option in your own country due to your excellent academic performance so apply to some US colleges and see if they provide enough financial aid to be affordable to your family. If not, stay in Peru for undergrad and see if grad in the US is a possibility.
We can help with those suggestions. There will be schools suggested you’ve never heard of but that will all give you a very good education. Getting a high SAT/ACT will offer more options so please sign up for that if you move forward. Also talk to your parents about the financials so you can complete the aid forms when that time comes.
You’ll have to adjust your plan but you can still try if you’re open to other options.
