A new study by the American Immigration Law Foundation estimates that job growth for the foreseeable future is heavily dependent on immigration. Economic Growth and Immigration: Bridging the Demographic Divide, says that:
U.S. economic growth projections for 2002–2012 are predicated on a growing supply of workers that likely will not be found in the native-born population alone. Absent a change in current immigration laws, undocumented immigrants will likely account for 1 in 8 new workers between 2002 and 2012. Rather than creating an orderly process by which needed workers enter the United States from abroad, static limits on employment-based immigration have diverted labor migration to undocumented channels or clogged the family-based immigration system.
