On May 26, 2011, the U.S. Supreme Court decided Chamber of Commerce of the United States v. Whiting, No. 09-115, which held that states could mandate employment verification and could suspend or revoke business licenses for an employer’s violation of immigration laws. Shortly thereafter, several states including South Carolina and North Carolina passed state immigration laws mandating employment verification and imposing penalties for failure to comply. This article summarizes the main provisions of each state law.
