Then maybe we should figure out why that is, and fix it, rather than continuing to import the droves of internationals who take university positions away from residents of this country.
Keeping internationals here for the sake of Academia is such a biased and stupid opinion to have. In engineering you are literally only relevant until people graduate. You should not be dictating policy for your sake alone.
If I can't get a job in Europe because they have to prove that there is no national qualified to do the job, then I don't see why our country should do the opposite.
