Amends the Immigration and Nationality Act to: (1) extend the special immigrant program for non-minister religious workers until January 1, 2010; and (2) extend the program until January 1, 2016, (to be effective March 1, 2009) if the Secretary issues such final regulations by December 31, 2008.
Directs the Inspector General of the Department of Homeland Security to report to Congress on such regulations' effectiveness by September 30, 2010.
