Immigration law in the United States generally includes the rights and obligations of persons who are not U.S. citizens to temporarily visit or more permanently reside in the U.S.—and for federal and state governments to enforce immigration laws regarding visitors and residents.

Most immigration law consists of federal statutes and regulations—but many state laws impact both legal and illegal immigrants—including employment checks, E-Verify, law enforcement, driver's license requirements, public benefits restrictions, and more.

In New York, as in all states, immigration law is primarily governed by federal statutes and regulations, as immigration is a matter under the jurisdiction of the federal government. This includes laws pertaining to visas, green cards, asylum, deportation, and citizenship. However, state laws can also have an impact on immigrants. New York State has adopted policies that are generally considered immigrant-friendly. For example, New York allows undocumented immigrants to obtain driver's licenses through the 'Green Light Law.' The state also limits law enforcement's cooperation with federal immigration authorities in certain situations, aligning with 'sanctuary' policies. Employment verification in New York follows federal guidelines, including the use of the E-Verify system for certain employers. Additionally, New York provides some public benefits and protections to immigrants regardless of their legal status, although eligibility for certain state-funded assistance programs may vary based on immigration status. It's important for immigrants in New York to understand both federal immigration laws and the specific provisions of New York State law that affect them.
