This handbook provides detailed treatment of the rapidly developing area of state law aimed at preventing the hiring of noncitizens unauthorized to work in the United States. Organized alphabetically by state, the handbook provides not only the full text of relevant state laws and state regulations but also provides in-depth analysis of those laws and regulations, the case law dealing with their validity and construction, and the impact on employer immigration compliance programs. It provides vital information on both the state immigration laws pertaining to employers in general and the state laws that focus specifically on public contractors and subcontractors.
