Through the Prism of National Security: Major Immigration Policy and Program Changes in the Decade since 9/11

The terrorist attacks of September 11, 2001 prompted the profound realignment of the U.S. immigration system, with national security and enforcement the dominant lens through which programs and budgets have been shaped over the past decade. The post-9/11 era has witnessed the largest government reorganization since World War II; increased information sharing and data collection across international, federal, state, and local law enforcement and intelligence agencies; the broad use of nationality-based screening and enforcement initiatives; the expansion of immigrant detention policies; and exponential increases in funding for homeland security-related immigration programs.

This fact sheet details the policy, programmatic, budget, and manpower changes that have happened in the immigration arena as an outgrowth of the 9/11 attacks.
