Immigrants play a vital role in the dynamic U.S. economy. Understanding the forces that drive immigration can help us design more effective immigration policies. These resources dicuss the economics of immigration; the incentive effects of immigration policies on migrants, native workers, and employers; and the benefits of comprehensive immigration policy reform.  The United States is a nation of immigrants and a nation of laws, and we value both historical legacies. Although immigrants continue to make positive
contributions to our nation and our economy, our current immigration laws have proven difficult to enforce and are not fully serving the needs of the American economy.
