"Comprehensive immigration reform was the subject of much discussion at the start of the 110th Congress. In the spring of 2007, the Senate considered several broad immigration reform measures aimed at addressing a host of perceived problems with the U.S. immigration system. These measures combined border security and interior enforcement provisions with provisions on temporary workers, permanent admissions, and unauthorized aliens. In June 2007, the Senate voted on a motion to invoke cloture on one of these measures (S. 1639), which, if approved, would have ultimately brought the bill to a vote. The motion failed, however, and the bill was subsequently pulled from the Senate floor. It is unclear whether the 110th Congress will again take up comprehensive immigration reform legislation. […] Among the other immigration-related issues that the 110th Congress may address are state and local enforcement of immigration laws, employment eligibility verification and worksite enforcement, Iraqi refugees, and documentary requirements for admission. At the same time, the 110th Congress has enacted some immigration-related provisions. Among them are refugee-related provisions included in the FY2007 Revised Continuing Appropriations Resolution; the U.S. Troop Readiness, Veterans' Care, Katrina Recovery, and Iraq Accountability Appropriations Act; and a measure to increase the number of Iraqi and Afghani translators and interpreters who may be admitted to the United States as special immigrants. The 110th Congress also has enacted provisions on border security and the Visa Waiver Program as part of a law providing for the implementation of the recommendations of the National Commission on Terrorist Attacks Upon the United States. This report discusses these and other immigration-related issues that have seen legislative action or are of significant congressional interest. […]"
