I'm curious about what goes through the minds of people who take that oath while retaining another citizenship. To them is it just meaningless words they have to say to get a check mark on paperwork? Do they regard any oath or agreement that isn't enforced by legal consequences as something they can ignore? Do they think of it as unfair and hence not worth feeling bad about?
