Carried forward by the efforts of over 1,000,000 members, NumbersUSA has emerged as the leading voice on immigration in America. Founded and led by author Roy Beck on the principle that exploding immigration levels were undermining other Congressional efforts aimed at improving the quality of life in America, the non-partisan immigration reduction organization NumbersUSA seeks to restore immigration numbers - both legal and illegal - in the United States to traditional levels in order to ensure long-term U.S. sustainability. NumbersUSA Education and Research Foundation is a non-profit, non-partisan immigration-reduction organization. We conduct research on the impacts of high numerical levels of immigration and educate the public, opinion leaders and policymakers on the results of those and other studies. Undergirding our work are beliefs in environmental sustainability, economic justice, the rule of law, and individual liberty, and opposition to federal immigration policies that threaten these values by forcing massive U.S. population growth.
