President Bush Has Called On Congress To Make Basic Pilot Mandatory And Provide The Department Of Homeland Security (DHS) With The Funding And Authority To Make Sure It Is An Effective Tool To Prevent The Hiring Of Illegal Workers. Basic Pilot is still optional, and most employers do not participate. Both the House and Senate immigration bills would require employers to use Basic Pilot. The President's FY07 budget requests $111 million to expand Basic Pilot for more employers to make use of the program.

Congress has expanded it to all 50 states and reauthorized it until Nov 2008, but hasn't acted to make it mandatory yet. That provision is included in most of the immigration bills that have been debated.
