Local law enforcement agencies have different policies about whether they will work with ICE. 

Contact a local immigrant rights organization to learn more about local laws and policies related to ICE detainers. These organizations can help you find an immigration attorney, give you advice about your immigration situation, or help advocate with ICE.


A detainer is a form from Immigration and Customs Enforcement (ICE) that asks law enforcement to hold you in criminal custody, even if you should be released. It also asks law enforcement to notify ICE before you are released from criminal custody. 

ICE might send a detainer to offices such as the sheriff, the police, a jail, or a prison.

Detainers are also called “ICE holds” or “immigration holds.”

ICE issues a detainer form when ICE believes you are not a U.S. citizen and could be deported from the U.S. You could be deported if you are undocumented, have lawful status and certain convictions, have violated the terms of your immigration status, or for reasons related to “national security.”

If ICE believes that you may be deported from the U.S., ICE issues a detainer form to the local jail, prison, or police. When a jail or prison decides to follow the requests in the detainer form, they might transfer you directly to ICE custody, or hold you at the jail or prison until ICE can come to arrest you.


ICE can learn about you when you are fingerprinted during an arrest by local police. The police or sheriff share fingerprint data and other arrest information with ICE. Police may also call ICE directly if they suspect you are not a U.S. citizen.

The ICE detainer form asks the jail to hold you for up to 48 hours after you are finished with your criminal custody.  In the past, weekends and holidays were not included in the 48 hours, but now they are included in the 48 hours. 

The ICE detainer form says that you must be released after 48 hours if ICE does not pick you up. The jail might mistakenly insist that they have to hold you for more time until ICE comes to arrest you.

When law enforcement offices cooperate with ICE detainers, they make it easier for ICE to arrest people. Following an ICE detainer request is voluntary and local law enforcement can decide whether or not to comply. This means the federal government cannot force the police, jail, or prison to hold you for ICE because of an ICE detainer.  If a city or state has a policy that they will not follow detainer requests, the local jail might not transfer or hold you for ICE.

If there is an ICE detainer filed against you, you should speak to your criminal defense attorney or local public defender office before paying bail. The attorney can help you understand any risks in paying bail.  For example, if you pay bail and the jail cooperates with ICE, they may keep you in criminal custody for up to 48 hours so ICE can arrest you.

If you are arrested by ICE, you may not be able to physically appear for your criminal case and defend yourself against the charges. The judge might issue a warrant against you for not attending your criminal court hearing. This could impact your criminal case and whether you get your bail money back.

If ICE arrests you from criminal custody, you may be taken to an ICE processing center. ICE will decide whether to put you in a detention center or release you. You could be held in any immigration detention center throughout the country. The ICE detainee locator has information about where a person is detained by ICE. 

During this process, ICE will ask you questions about your immigration and criminal history. Any information you share with an ICE officer, including place of birth, can be used against you.

You or your loved one should talk to an immigration attorney to get advice about your immigration situation, options for release from detention under bond, and defenses to deportation.
