thats putting a lot of responsibilities on you.
People are leaving sg for universities & such, your family
is expecting you to go back sg to do your universities?
(doiing that entails having to to do NS.)
Its up to you seriously. And your parents shouldnt have
that sort of expectation.
USA & Singapore arent that much different in terms of
expenses. You might want to check thru your local collages to
find out which is more cheaper.
USA, you get your driving licence faster and schools easier.
I've known folks that completed their NS and then give up their
sg citizenship, because they felt they are better off
elsewhere.
