What Does ICE Stand For?

ICE stands for Immigration and Customs Enforcement

Each letter maps to a word in the agency name:

• I = Immigration
• C = Customs
• E = Enforcement

The "and" is dropped, as it usually is in agency acronyms. The official name starts with "U.S.", so you will also see "U.S. ICE" on badges, vehicles and press releases. People say it as the word "ice," not "I C E."

ICE was formed when the federal government reorganized after the September 11 attacks. Parts of the former Immigration and Naturalization Service and the U.S. Customs Service were combined, and the new agency was placed under the Department of Homeland Security.

What does ICE stand for in law enforcement and immigration?

If you searched what ICE stands for in law enforcement or in immigration, the answer is the same agency. Its work falls into two main parts:

• Enforcement and Removal Operations (ERO) locates, arrests and detains people who are in the country without legal status or who have orders to leave, and carries out removals, often called deportations.
• Homeland Security Investigations (HSI) looks into crimes that cross borders, such as human trafficking, smuggling, child exploitation, counterfeit goods and money laundering.

ICE also has lawyers who represent the government in immigration court. The agency does not decide who gets a green card or citizenship; another office handles those applications.

ICE in the news and in government

ICE appears often in news stories about immigration policy, arrests and detention centers. The agency is a frequent subject of public debate. Some people want stronger enforcement and see the agency as necessary for border security and public safety. Others want limits on its methods or a different approach to immigration overall. Both views show up in headlines, so it helps to read the whole story rather than the abbreviation alone.

Other ICE meanings: phones and vehicles

So what does ICE stand for in vehicles? It means a car that burns gasoline or diesel, as opposed to an EV. Car writers use it to compare the two types.

How to write the ICE acronym

The standard form is all capitals and no dots: ICE. The form I.C.E. is occasionally seen on signs or in older print, and it means the same thing. In news writing, the agency name is usually spelled out on first mention, "U.S. Immigration and Customs Enforcement," and shortened to ICE after that. Because the word begins with a vowel sound, it takes "an": "an ICE agent," "an ICE office."

For phone contacts, many people simply type ICE before a name. Some phones now also offer a medical ID screen that works the same way.

Agencies people mix up with ICE

Three agencies under DHS handle different parts of immigration, and the letters get mixed up all the time.

• CBP, U.S. Customs and Border Protection, works at the border, airports and seaports, inspecting people and goods as they enter.
• USCIS, U.S. Citizenship and Immigration Services, reviews applications for visas, green cards and citizenship.
• ICE works inside the country, on enforcement and investigations.

Airport screening is a separate agency again, the TSA. The government acronyms guide lists many more federal agencies by their letters. You can also compare with the FBI, which sits in the Justice Department.
