Immigration and Customs Enforcement
Immigration and Customs Enforcement (ICE) is the second largest federal criminal investigations agency, only exceeded by the Federal Bureau of Investigation. The agency was formed, along with US Citizenship and Immigration Services, when the federal Immigration and Naturalization Service was dismantled in 2003. ICE is tasked with civil and criminal enforcement of immigration laws and with investigating the movement of people, drugs, weapons and goods across US borders. Additionally, it has been involved in intellectual property enforcement, including the controversial "Operation In Our Sites" domain name seizures.
