ICE--
[announcer's voice over]

"Among the Department of Homeland Security (DHS) law enforcement agencies, ICE has the most expansive investigative authority and largest force of investigators. Our mission is to protect the American people by combating terrorists and other criminals who cross the Nation’s borders and threaten us here at home. The men and women of ICE accomplish this by investigating and enforcing the Nation’s immigration and customs laws. Working overseas, along the Nation’s borders, and throughout the Nation’s interior, ICE agents and officers are demonstrating that the newly merged customs and immigration authorities constitute an effective mechanism to identify, disrupt, and dismantle criminal organizations that violate the Nation’s borders and the Nation’s customs and immigration laws. By leveraging the full enforcement potential provided by the new and unique blend of customs and immigration authorities, ICE agents and officers—together with our DHS and other federal counterparts and with the assistance of tribal, state and local law enforcement entities—are making it more difficult for potential terrorists and transnational criminal groups to move themselves, their supporters, or their weapons across the Nation’s borders through traditional human, drug, contraband, or financial smuggling networks, routes, and methods. Specifically, this work serves to dismantle the criminal business networks that seek to exploit the Nation’s borders. Moreover, our presence extends from the border well into the interior of the United States and deters illegal immigration by making clear, that it is not acceptable to fail to fully comply with the Nation’s immigration laws. These efforts implement the Nation’s critical homeland security priorities and strengthen respect for the Nation’s laws."

By the way...
just in case anybody was wondering, it is actually the Department of Detention and Removal(DRO) who is the primary enforcement arm within ICE for the detention, apprehension and removal of the legal aliens from the United States.

their mission statement although not as elaborate is, "DRO promotes public safety and national security by ensuring the departure from the United States of all removable aliens through the fair and effective enforcement of the nation's immigration laws."
their 10-year vision to meet all the mandates will require

*visionary leadership at all levels of the organization
*an effectively trained and educated professional workforce
*the right levels of critical resources, e.g. professional facilities and infrastructure and
*effective, responses, and acrid command-and-control communication computer intelligence (C41) systems that advance the DRO mission

there you have it from the horses mouth what they need to go after illegal aliens.
