The problem is that in order to emigrate from where they are (third-world / developing) to another country (likely first-world / developed), they would need to move on one of these visas: (a) student (b) worker (c) family member of someone already in said country. (a) requires a substantial financial outlay, (b) requires a job offer AND visa sponsorship from a hiring company and (c) is probably easiest but requires a family member to be already present in the country with a solid visa status.
