(sorry of getting in this debate about sponsoring students overseas, but i feel like i have need to reply)
the reason i disagree with the sympathetic adults part was because you suggested call and walk-in to HR offices and etc which i think is really not something feasible because if it wasn't part of the plan to offer these students to study overseas, i SERIOUSLY doubt they will give just because someone talented asking them because as i mentioned, why should they when they can hire one of similar qualities? yes i get it, the uni that offers them have done the selection for these corporations, so it's easier to single out the good ones, but seriously, they can still hire one right?
after all, they are running a business, they are not looking for the next mark, bill or steve. even if they are, scholarship has proved to be (maybe not, i don't know cause i hear stories, though i don't like jumping to conclusions without actual numbers from reliable sources) a VERY risky investment with all these brain drain, and stories about scholars running off
i'm not saying one shouldn't try. but i really don't see why HR people will try so hard to help. 'i orang malas, kalau saya kerja HR, saya biarkan sahaja, melebihkan kerjaku untuk anak orang lain.'
one should not say whether one's parents should be more supportive, for one cannot judge before one's a parent one-self and without knowing what's one's parents' problems are.
anyway, to the person in this case, try to reason with your parents, i'm sure you can understand why they want you to do it. Be patient
somehow i feel that (from your response) at least you have a good attitude in approaching this matter, that's real cool
