About U.S. Citizenship and Immigration Services (USCIS)

U.S. Citizenship and Immigration Services is a federal agency within the U.S. Department of Homeland Security that oversees lawful immigration to the United States. Its work centers on reviewing applications and petitions for green cards, naturalization, work authorization, and certain humanitarian protections, and it issues immigration documents. It also determines eligibility and provides citizenship documentation for people who acquired or derived citizenship through their parents, and it manages the first step of intercountry adoptions by U.S. citizens.

The agency's functions include scheduling oath ceremonies after approved naturalization, adjudicating petitions for nonimmigrant workers such as H-1B and O-1 classifications, and offering online case tracking and filing tools. Third-party guides and mapping services describe a New York City Field Office at 26 Federal Plaza in Manhattan, where interviews are held by appointment, along with field offices in Brooklyn and Long Island City and a Long Island office in Holtsville. Applicants are generally directed to confirm the location listed on their own notices.
