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.

Speaking from first hand interaction with Asian children/families all throughout my schooling, regardless if they were born in UK, there is a definite difference in culture with regards to education, failing exams is to bring shame on yourself and embarrassment for your parents.

Fair enough for those that were not that clever, but they did put some effort into it.

Majority I knew were born here, spoke perfect English AND a second language.
