The United States immigration system is built on a complicated set of laws, rules, and procedures. In order to obtain the best possible outcome in a given immigration proceeding, it helps to understand the laws that underlay the process. Fortunately, immigration laws are the same throughout the country, since they are governed at the federal level; but some state laws effectively impact immigrants as well. FindLaw's Immigration Laws and Resources section covers the various federal laws and regulations governing U.S. immigration; overviews of state laws that impact immigration and legal status; directories of government agencies that handle immigration issues; links to relevant government forms; and more.
