Also when you cite sources ensure that they back your claim. This says international students, which includes those in undergrad courses studying who knows what.
The USA has an economy 12X the south of South Korea's, yet doesn't even produce double the engineers. It is quite clear then that SK trains almost all of those that it needs and likely also trains others coming from other Asian countries.
