The death of Osama bin Laden has triggered conversations about how his terrorist actions affected Americans since the tragedy of Sept. 11, 2001.
One of the outcomes of 9/11 is clearly visible around San Diego and the U.S. Increased security and scrutiny on how the 9/11 hijackers entered and stayed in the U.S. highlighted the operations of the former Immigration and Naturalization Services agency.
In response to the problems that were identified the federal government created new policies for the governance of immigration and borders and organized a new agency to oversee it all, the Department of Homeland Security.
The Department of Homeland Security became responsible for the work of the old Immigration and Naturalization Services agency, which oversaw all immigration duties from border security to citizenship applications.
Under DHS those responsibilities were split between the newly created U.S. Citizenship and Immigration Services, which oversees legal immigration issues, Immigration and Customs Enforcement, the enforcer of immigration laws in the U.S., and Customs and Border Protection, a force responsible for border and port security.
