Why "Secure the Borders First!" Won't Solve the Problem

Those who insist on securing the borders first, are ignoring the source of almost half of the illegal immigrants.  An estimated 40% to 50% of the illegal immigrants in the U.S. come here legally and then overstay their visas.  Securing the border will do nothing to solve this problem.  Until we streamline deportation for those who come legally, but remain illegally, we will continue to have a serious problem with illegal immigrants.
