From US Fed News:

WASHINGTON, July 24 — Rep. Sam Graves, R-Missouri, has introduced the Emergency Immigration Workload Reduction and Homeland Security Enhancement Act of 2007 (H.R. 3064), legislation that would “suspend certain nonessential visas, in order to provide temporary workload relief critical to the successful reorganization of the immigration and naturalization functions of the Department of Homeland Security, to ensure that the screening and monitoring of arriving immigrants and nonimmigrants, and the deterrence of entry and settlement by illegal or unauthorized aliens, is sufficient to maintain the integrity of the sovereign borders of the U.S.”

The bill was introduced on July 17. It was referred to the House Judiciary Committee.
