ICE Detention in Idaho: How to Find and Support a Detained Loved One

If someone you love has been detained in connection with immigration in Idaho, it helps to understand how the system works here, because Idaho is mostly a starting point, not a destination. The state has no dedicated immigration detention facility of its own. Instead, people are held for a short time in local county jails and then transferred to Immigration and Customs Enforcement, known as ICE, and moved to a facility in another state. Where they go can vary, from the Pacific Northwest to Nevada and sometimes California. That means the window while your person is still in Idaho is short, so the two most urgent things you can do are find exactly where they are, 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 Idaho to wherever they are sent, 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.

The locator matters even more in Idaho because people get moved out of state, sometimes more than once. A search that shows your person in an Idaho county jail today may show them in Washington, Nevada, or California next week, so check it again every few days. If your person was just booked into a local jail, you may also be able to look them up on that county jail's own roster before ICE takes custody. If you cannot find them, call the ICE detention reporting line at 1-888-351-4024. Idaho is overseen by the ICE Enforcement and Removal Operations Salt Lake City field office, which covers Idaho, Utah, Nevada, and Montana, and which has an office in Boise that handles Idaho.

Where ICE holds people in and from Idaho

Idaho does not have a dedicated immigration detention center. Instead, ICE relies on local county jails that hold people under contracts known as intergovernmental service agreements. Several Idaho jails have been used this way, including the Canyon County jail near Boise, the Elmore County jail in Mountain Home, the Mini Cassia Justice Center in Burley, and the Kootenai County jail in northern Idaho. People are often held only a short time, sometimes around 72 hours at a staging jail, before being moved on.

From there the path leads out of state, and the destination depends on space and circumstances. Many people are taken to the Northwest ICE Processing Center in Tacoma, Washington, a large facility that serves the Pacific Northwest. Others are moved south to the immigration detention center in Pahrump, Nevada, which serves the Salt Lake City field office region, and some have been sent as far as California. Northern Idaho jails have at times even held people detained across the border in eastern Washington. The lesson for families is to assume your person will be moved, keep checking the locator, and be prepared for the case to be handled in another state.

It is also worth knowing that the region's detention capacity is growing. ICE has purchased a large warehouse in the Salt Lake City area that it plans to convert into a regional detention center, which could change where people from Idaho are held. Because the picture keeps changing, rely on the live locator rather than any fixed list.

How someone ends up in ICE custody in Idaho

In Idaho, most people enter immigration custody through local jails. 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. Idaho jails have agreements with ICE that make this routine, and the state has also cooperated in other ways, including a program in which state authorities transfer people from Idaho prisons to ICE after they finish their sentences.

What this means in practice is that a local arrest, or the end of a jail or prison term, can lead to immigration custody. If your person was first arrested or jailed locally, that is usually how they came to ICE's attention.

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. Because Idaho has no detention facility, the case will usually be heard near wherever your person is transferred, often at the immigration court that serves the Tacoma facility in Washington. You can 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. An immigration attorney can tell you quickly which category applies, which is one more reason to act fast, especially given how quickly people leave Idaho. 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

Move quickly and find a lawyer first. Idaho has a limited number of immigration attorneys, and because your person may be moved out of state fast, reach out as soon as you can, and understand that the case itself may continue in Washington, Nevada, or California. Have the A-Number ready when you call.

Track the transfer. Keep checking the locator so you always know which facility your person is in, since money, phone, and visitation all depend on where they are at that moment.

Put money on their account and learn the phone system. While your person is in an Idaho county jail, the deposit and phone systems are run by that jail and its vendors; after a transfer, they are run by the receiving facility and its vendors. Call to confirm how each works.

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. A transfer to another state can leave a person isolated and far from everyone they know, frightened and cut off, 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 Idaho to wherever they are sent. 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.
