The Counterterrorism and Criminal Exploitation Unit operates in conjunction with Immigration and Customs Enforcement under the direction of Homeland Security. The unit's mission is the prevention of illegal immigration through fraudulent representation.
According to ICE, violation of a non-immigrant visa is one focus of the counter-terrorism unit. In addition, it is charged with the surveillance of suspected terrorists and their associated groups. The student visa system is also carefully scrutinized. Two sections within the unit utilize federal databases to accumulate information about visitors to the United States. These statistics assist the unit in identifying criminal activity or potential national security threats.
