Immigration and Customs Enforcement has two main duties: investigating immigration crime and what else?

Immigration and Customs Enforcement (ICE) is a vital component of the Department of Homeland Security, focusing on the enforcement of immigration laws. One of its primary responsibilities is to identify and apprehend removable aliens, which refers to individuals who are in the country unlawfully or who have violated the terms of their visa. This duty involves a comprehensive approach to enforcement, including investigations, surveillance, and collaboration with other law enforcement agencies.

Identifying and apprehending removable aliens requires not only operational enforcement but also adherence to legal protocols to ensure that these actions are conducted within the framework of the law, respecting both national security and individual rights. This is essential for maintaining the integrity of immigration laws and ensuring that those who pose a risk to public safety can be effectively managed within the system.

In contrast, the other options do not encapsulate the primary responsibilities of ICE. Helping immigrants secure citizenship is primarily handled by U.S. Citizenship and Immigration Services (USCIS), not ICE. Tracking drug trafficking activities falls under the purview of agencies such as the Drug Enforcement Administration (DEA), while overseeing border security is mainly managed by Customs and Border Protection (CBP). Each agency has distinct roles within the larger framework of homeland security and immigration enforcement.
