ICE stands for Immigration and Customs Enforcement. It is a federal law enforcement agency within the U.S. Department of Homeland Security. It was created in 2003 after the September 11 attacks, when several agencies were reorganized under the new Department of Homeland Security.

ICE has two main branches:

How large is ICE?

ICE has roughly 20,000 employees in total. Not all are armed officers. The workforce includes:

Only a portion of ICE employees are armed law enforcement officers.

Is ICE expanding?

Yes. Congress recently approved substantially increased funding for immigration enforcement, including money to:

The exact hiring targets and appropriated amounts depend on the most recent federal budget and appropriations laws, but the direction has clearly been toward significant expansion.

Is ICE a "private army" for the president?

No, not in the usual meaning of that term.

ICE is:

A "private army" generally refers to an armed force loyal to an individual rather than to the government and law. ICE is not organized that way. However, because immigration enforcement priorities are set by each administration, presidents can direct ICE to emphasize different priorities within the law. For example, one administration may prioritize recent border crossers, while another may direct ICE to pursue a broader range of people living in the country without authorization.

Why is ICE controversial?

Supporters argue that ICE:

Critics argue that ICE has at times:

Some lawsuits and court rulings have found specific ICE actions unlawful, while many other operations have been upheld as within the agency's legal authority. Oversight comes from Congress, federal courts, inspectors general, and internal review processes.

Is ICE "paramilitary"?

ICE officers carry firearms, wear body armor when appropriate, execute search and arrest warrants, and receive law enforcement training. Some specialized teams use tactical equipment similar to other federal law enforcement agencies such as the Federal Bureau of Investigation or the U.S. Marshals Service.

The term "paramilitary" is sometimes used descriptively because of this equipment and organization. Others avoid the term because ICE is a civilian law enforcement agency, not part of the military. Whether to call it "paramilitary" is partly a matter of definition and perspective.

Are there calls for greater constraints?

Yes. Proposals from critics include:

Others argue that existing legal authorities should be preserved or expanded to improve enforcement of immigration laws.

The broader picture

ICE has become one of the most visible federal law enforcement agencies because immigration is one of the country's most contentious political issues. The agency's role and size have changed over time depending on congressional funding and the priorities of different presidential administrations. As a result, debates about ICE often reflect broader disagreements about immigration policy, border security, civil liberties, and the balance between enforcing immigration law and protecting the rights of noncitizens.
