This fact sheet outline how ICE aims to: target immigration violators and fugitives; target human traffickers and smugglers; protect worksites; and protect victims. "U.S. Immigration and Customs Enforcement (ICE) was established in March 2003 as the largest investigative arm in the Department of Homeland Security (DHS). ICE unites the functions, resources, and legal authorities of several previously fragmented border and security organizations into an integrated homeland security agency focused on investigations and enforcement. ICEs mission is to prevent terrorist and criminal acts by targeting the people, money, and materials that support terrorist and criminal networks. Immigration enforcement is one of ICEs primary missions and a vital component of homeland security. Recognizing that terrorists and criminals have exploited vulnerabilities in our border security to enter and remain in the United States, ICE has developed a comprehensive and aggressive strategy to restore integrity to the nations immigration system."
