Are massive legal immigration and massive illegal immigration related? If so, how? Many in policy circles hold a view of "Legal immigration, good; illegal immigration, bad." The logical extensions of such a simplistic perspective are to assume that the overall level of legal immigration does not matter and to underestimate any correlation to illegal immigration. But the facts show a distinct connection exists... Many aliens who receive a permanent resident visa each year have spent years living in the United States illegally... "Anchor babies" and "chain migration" provide opportunities for many aliens to plant roots in the United States. Those aliens might not otherwise have done so.
