Looks like it was signed into law in 1996 and CA., AZ., AL., FL., N.C. were the first to sign up. (I think Clinton was president in 1996, but I could be wrong.)
History of 287(g)
The Illegal Immigration Reform and Immigrant Responsibility Act of 1996 added Section 287(g), performance of immigration officer functions by state officers and employees, to the Immigration and Nationality Act. This authorizes the deputy director of ICE to enter into agreements with state and local law enforcement agencies, permitting designated officers to perform immigration law enforcement functions, provided that the local law enforcement officers receive appropriate training and function under the supervision of ICE officers . . .
Fact Sheet: Delegation of Immigration Authority Section 287(g) Immigration and Nationality Act
The Illegal Immigration Reform and Immigrant Responsibility Act of 1996, Division C of Pub.L. 104-208, 110 Stat. 3009-546, enacted September 30, 1996 (often referred to as "i-RAI-ruh" by federal appellate law clerks, and sometimes abbreviated as "IIRAIRA" or "IIRIRA") vastly changed the immigration laws of the United States.
This act states that immigrants unlawfully present in the United States for 180 days but less than 365 days must remain outside the United States for three years unless they obtain a pardon. If they are in the United States for 365 days or more, they must stay outside the United States for ten years unless they obtain a waiver. If they return to the United States without the pardon, thet may not apply for a waiver for a period of ten years.
Constitutional issues within the law
Previously, immediate deportation was triggered only for offenses that could lead to five years or more in jail. Under the Act, minor offenses such as shoplifting may make individuals eligible for deportation. When IIRIRA was passed in 1996, it was applied retroactively to all those convicted of deportable offenses.
However, in 2001, the U.S. Supreme Court decided that Congress did not intend IIRIRA to be applied retroactively to those who pleaded guilty to a crime prior to the enactment of IIRIRA if they would not have been deportable at the time that they pleaded guilty in (INS v. St. Cyr).
IIRIRA's mandatory detention provisions have also been repeatedly challenged, with less success.
Deportation issues
Deportees may be held in jail for months, even as much as two years, before being brought before an immigration board, at which defendants need to pay for their own legal representation. In 2001, the Supreme Court curtailed the Immigration Service's ability to hold deportees indefinitely in Zadvydas v. Davis.
The Act has been applied much more vigorously since 9/11. At least 1000 British citizens were affected by the law in 2003.
Section 287(g) and relations between federal and lower levels of government
IIRIRA addressed the relationship between the federal government and local governments. Section 287(g) is a program of the act that permits the Secretary of the Department of Homeland Security to enter into agreements with state and local law enforcement agencies, permitting designated officers to perform immigration law enforcement functions, pursuant to a Memorandum of Agreement. This section does not simply deputize state and local law enforcement personnel to enforce immigration matters.
This provision was implemented by local and state authorities in five states: California, Arizona, Alabama, Florida and North Carolina by the end of 2006.[
