I feel that he's hinting that the government, particularly Republicans, should draw up some sort of legislature that will allow well educated, in demand individuals come to the USA legally. Perhaps they will have a special program for "DREAM"ers that will require them to return to their home country and their cases will be reviewed on the grounds of how desirable their skills are. It will disqualify TONS of "DREAM"ers but I have a feeling that this is what they will come up with.
