U.S. Secretary of Education Arne Duncan will deliver the keynote address at the Migration Policy Institute's National Center on Immigrant Integration Policy E Pluribus Unum Prizes Awards Ceremony Wednesday in Washington. The award will recognize four exemplary immigrant integration projects that serve as models to others who are helping immigrants and their children join the mainstream of U.S. society and build stronger ties between immigrant and native-born communities. An additional Corporate Leadership Award will be presented to a major U.S. corporation in recognition of business practices that are supporting the integration of its immigrant employees.
