Whether it is the changing demographics of its customers, fluctuating and unpredictable demand for immigration services, or the rise of new security threats, the U.S. Citizenship and Immigration Services (USCIS) plays an integral role in ensuring the security and integrity of the nation’s immigration system. “Our agency,” explains Alejandro Mayorkas, director of USCIS, “was created as part of the Department of Homeland Security, following the Homeland Security Act of 2002. Our portfolio is really the administration of our country’s legal immigration system. We have the responsibility of ensuring the integrity of the system that we administer and safeguarding our national security. It is in this latter function that we fit into the Department of Homeland Security’s overarching mission of securing our homeland.”
