What is USCIS?
USCIS stands for United States Citizenship and Immigration Services, and it is the primary agency that oversees lawful immigration.
The USCIS was created following the Homeland Security Act of 2002. The Act was written in response to the attacks on the World Trade Center on Sept. 11, 2001. Beginning on March 1, 2003, the USCIS took on many of the responsibilities of the Immigration and Naturalization Service, INS, which ceased to exist. Two other agencies were also created that would take on other functions of INS: Immigration and Customs Enforcement, ICE, and Customs and Border Protection, CBP.
The USCIS processes most of the immigration forms people file, like applications for citizenship, green cards, and work permits.
