Homeland Security

The U. S. Department of Homeland Security (DHS) was formed on November 25, 2002, and is charged with protecting the United States within, at, and outside its borders. It is the main federal agency responsible for dealing with terrorist threats.

In 2003, DHS absorbed the Immigration & Naturalization Service (INS), including the Border Patrol (BP). Under DHS, the immigration enforcement and services functions are handled by Immigration & Customs Enforcement , U. S. Customs & Border Protection, and Citizenship & Immigration Services.
