We should make immigration another tool to grow the economy.  The labor market should control the inflow and outflow of immigrants.  With unemployment so low, we need more people to help further expand our economy.  All people who do not pose a threat to America and will not be a drain on the treasury should be allowed to come here and participate in our economy.  By ending the drug war and ending federally run welfare programs we will end the perverse incentives to come here, and we will be better off for it.
