U.S. Citizenship and Immigration Services (USCIS) is an agency of the United States Department of Homeland Security (DHS) that administers the country's naturalization and immigration system. It is a successor to the Immigration and Naturalization Service (INS), which was dissolved by the Homeland Security Act of 2002 and replaced by three components within the DHS: USCIS, Immigration and Customs Enforcement (ICE), and Customs and Border Protection (CBP).
USCIS performs many of the duties of the former INS, namely processing and adjudicating various immigration matters, including applications for work visas, asylum, and citizenship. Additionally, the agency is officially tasked with safeguarding national security, maintaining immigration case backlogs, and improving efficiency. Ur Jaddou has been the director of USCIS since August 3, 2021.
