If someone you love has been detained by Immigration and Customs Enforcement, known as ICE, in Oklahoma, it helps to know how detention is set up here. Oklahoma holds immigration detainees in a mix of facilities: a large private detention center, a couple of other private and county-run correctional facilities, and a number of local county jails. The main destination for people detained in the state is now the Diamondback Correctional Facility in Watonga, about 70 miles northwest of Oklahoma City. Where your person is held often depends on where they were detained, and people are frequently moved. The two most urgent things you can do are find exactly where they are being held, and get an immigration attorney involved right away.
It helps to understand the nature of this. ICE detention is civil, not criminal. A person is not being held as punishment for a crime; they are being held to secure their presence for immigration proceedings or removal. And unlike criminal court, immigration court does not provide a free, government appointed lawyer, which is why finding legal help early is so important.
One number matters more than anything else through all of this: the Alien Registration Number, called the A-Number. It is a nine digit number assigned to the case, found on immigration paperwork, a work permit, or court notices. Write it down and keep it close, because it follows your person from facility to facility, and it is the key to locating them, posting any bond, and working with a lawyer.
How to find someone in ICE custody
ICE runs a free public tool called the Online Detainee Locator System, at locator.ice.gov. You can search by the A-Number, which is the most reliable way, or by the person's full name plus their country of birth and date of birth.
A few things make the difference between finding your person and coming up empty. The locator only matches names spelled exactly the way the government entered them, so if you get no result, try different spellings, swap the order of first and last names, and try with and without a middle name. Children under 18 do not appear in the system at all. And there can be a lag of a day or more before a newly detained person shows up.
Because people are often moved between facilities in Oklahoma, check the locator again every few days. Oklahoma falls under the ICE Enforcement and Removal Operations Dallas field office. You can also call the ICE detention reporting line at 1-888-351-4024 if you cannot locate your person.
Where ICE holds people in Oklahoma
The primary destination for people detained by ICE in Oklahoma is now the Diamondback Correctional Facility in Watonga, a large private prison run by the company CoreCivic that reopened in 2026 to hold immigration detainees. It can hold a large number of people and sits about 70 miles northwest of Oklahoma City.
Beyond Diamondback, Oklahoma houses ICE detainees at the Cimarron Correctional Facility in Cushing, the Kay County Detention Center in Newkirk, the Grady County Law Enforcement Center in Chickasha, and the David L. Moss Criminal Justice Center in Tulsa, along with a number of local county jails. Some of these places hold people only briefly before they are moved to a larger facility like Diamondback or transferred elsewhere. Because the location can change quickly, always rely on the live locator to confirm where your person actually is.
How someone ends up in ICE custody in Oklahoma
Many people come into ICE custody after contact with local law enforcement. When a person is booked into a county jail, ICE can place a detainer, also called an ICE hold, which is a request to keep the person for up to 48 hours beyond their normal release so ICE can take custody. Some Oklahoma agencies cooperate with ICE through formal 287(g) agreements, while others use their own arrangements to allow ICE access in their jails. People are also taken into custody through ICE's own enforcement in the community.
If your person was first arrested or stopped locally, ask the attorney exactly how they came into ICE custody, because the circumstances can matter to the case.
How the process and your person's rights work
Immigration cases are handled in immigration court, run by a separate agency called the Executive Office for Immigration Review, not by ICE. Hearings for people detained in Oklahoma are generally conducted by video from the facility, and depending on the facility, the case may be assigned to an immigration court outside the state. Your attorney can confirm which court is handling the case. You can also check case status through the court's automated system using the A-Number.
Here is what families most need to know about rights. A detained person has the right to be represented by a lawyer, but at their own expense, because the government does not provide one in immigration proceedings. They have the right to a list of free or low cost legal service providers. They generally have the right to a hearing before an immigration judge, and in many cases the right to ask that judge for release on bond. Some people are eligible for bond, which a judge can set and which can then be paid for release while the case continues; others fall under mandatory detention and are not eligible. In some situations, lawyers also turn to the federal courts to challenge a detention. One more thing worth knowing: a detained person should not sign documents giving up their rights, such as a voluntary departure form, without talking to a lawyer first.
How families can help from the outside
Find a lawyer early. The rapid growth in detention across Oklahoma has made experienced immigration attorneys hard to reach, so start the search quickly, and have the A-Number ready when you call. Oklahoma has immigration attorneys and nonprofit legal organizations that can help.
Learn the facility's system, because it differs from one place to the next. The rules for adding money, phone calls, and visits are set by the specific facility where your person is held. Once you have confirmed the current location on the locator, call that facility to learn its rules for deposits, phone, mail, and visitation, including identification requirements and the visiting schedule.
Track any transfer. Keep checking the locator so you always know which facility your person is in, since money, phone, mail, and visitation all depend on where they are, and in Oklahoma a move from a county jail to Diamondback or another facility can happen with little notice.
Keep the paperwork organized. Hold onto every document with the A-Number, every court notice, and every receipt, and share copies with the attorney.
Staying connected matters more than anything
Through all of the logistics, do not underestimate the simple power of staying in touch. Being held in a remote facility, often far from home and moved without much warning, can be deeply isolating, and steady contact from home is one of the few things that genuinely helps a person hold on.
Letters and photos are the backbone of that connection. They are something your person can keep, read again on a hard night, and hold as proof that home has not let go, and they can follow your person from one facility to the next. InmateAid can help you send physical mail and photos to your loved one, printed and delivered the right way so it reaches them inside. Use it to send pictures of family, words of encouragement, or simply a reminder that someone is fighting for them on the outside. That steady contact, alongside a good lawyer, is the most practical support you can give while the case moves forward.
