there's also a fair number of students and graduates from certain countries or related to certain peoples that he might want to help in exchange for who-knows-what.
the one thing that is certain, is he isn't proposing it for the benefit of 'immigrants' or 'foreign students' or even for the betterment of america.. but rather, for himself. it's always about him.
OK, I just didn't hear the times he said he opposed them. I do remember him saying we should increase them, since at the time I thought that was a good idea (not sure anymore, since they can so easily be used to just bring in lower paid people instead of how they are intended).
