context_page_description: The United States Immigration and Naturalization Service was an agency of the Department of Justice from 1933 to 2003. The agency ceased to exist under that name on March 1, 2003. This is when most of its responsibilities were transferred to three new agencies. These were the U.S. Citizenship and Immigration Services, U.S. Immigration and Customs Enforcement, and U.S. Customs and Border Protection. All were within the newly created Department of Homeland Security, as part of a major government reorganization following the September 11 attacks of 2001.
