What? Why would it even matter if they're going through the same education?

IIRC it's been proven that it in fact does matter on larger scale at least, individuals are a different matter of course. if you put aside the genetic differences which can vary from person to person regardless of where they're from, if you're an immigrant you might not adjust to your new country as well as natives do, you could have, even if only small, language barrier etc which can have negative impact on what you learn from the same education, your culture at home, even if you're born in the "new country", might have impact on how you learn etc etc.
