I'm not sure if this is the sort of thing you're asking about, and I didn't do this myself but there is a thing called the "International Baccalaureate", it's a sort of education plan that regardless of where you are, if you follow it you would be prepared for higher education/work basically anywhere in the world (so if you were in Costa Rica, like I am, and got it, when you are 18, you could go to the US, Canada, the UK, or the EU for university, with minimal or no classes to "catch up")
