not know where is a family member detained It is one of the most distressing situations that an immigrant family can go through in the United States. Sometimes the latest news was a short call. Others, someone simply stopped responding to messages after an immigration appointment, a traffic sustain watch over, or an operation. The uncertainty becomes desperate: Did ICE stop him? Is he in a local jail? Did they transfer him? Are you still in the same city?
Although the process is not always fast or transparent, it is There are official tools to try to locate a person in immigration custody. The problem is that many families do not know where to start, what information they need or what to do if the name does not appear in the system.
If you suspect that a family member was detained by immigration authoritiesthis guide can help you sort through your search and understand where it could be according to the state where the arrest occurred.

The first step: verify if ICE has the person in custody
The official tool to search for detainees It is the system of the Immigration and Customs Enforcement Service (ICE), known as the Online Detainee Locator System.
There you can search in two ways. The most effective is with the A number, also called A-Quantity or foreigner number. It is an immigration identifier that usually appears on immigration documents, work permits, USCIS notifications or court records. If you have that information, the search is usually much more precise.
If you don’t have it, you can still try with full name, date of birth and country of birth.
Here is an important detail: If the person was arrested only a few hours ago, they may not yet appear in the system. It may also happen that the name has been uploaded with errors, with the last name inverted or with a variation different from the one you usually use.

What to do if it does not appear in the ICE search engine
The fact that it does not appear does not necessarily mean that it is not detained. Many families get stuck at this point and assume the worst, but there are several possible explanations. The most common is processing time. A recent arrest may take time to reflect.
Another possibility is that the person has not yet been formally transferred to immigration custody and remain in the hands of another authority.
It also happens that the administrative records do not exactly match the name the family knows. In that case, it is advisable to try again a few hours later (especially if the arrest was on the same day).

Recommendations if you can’t find your family member in the official search engine
- Try different variants of the name: With second surname, without accents, with inverted or abbreviated names.
- Contact your local county jail: In many cases, the first destination is not ICE but a local jail.
- Call the ICE regional office: If you know in which city the arrest occurred.
- Consult with an immigration lawyer: If there was already an open case or a pending hearing.

Texas: An arrest can end hundreds of miles from where it occurred
Texas is one of the states where this type of situation generates the most uncertainty because transfers are frequent. A person detained in Houston could end up in another city. Same thing for someone arrested in Dallas, San Antonio, Austin, El Paso, McAllen or Laredo.
The fact is that, due to its proximity to the border and the volume of immigration operations, Texas concentrates multiple detention centers and constant movements between facilities. For families, that means finding a person quickly isn’t always easy.
Florida: immigration tightening raised concern among immigrants
Florida has become one of the most sensitive states for the immigrant community in recent years. If an arrest occurred in Miami, Orlando, Tampa, Fortress Lauderdale or Jacksonville, the person could first go through local facilities before appearing in federal records.
That often creates hours—or even longer—of uncertainty for those trying to locate it. In some cases, the arrest does not even begin as an immigration operation, but as an interaction with local authorities.
California: system may be more complex to follow
California has the largest immigrant population in the country, but the institutional map is less linear. Not all jurisdictions collaborate equally with ICE, which can make it more confusing to understand where a detained person ended up. The most common cases are concentrated in Los Angeles, San Diego, San Francisco and Sacramento.
Depending on the case, you could be in a federal facility, a contracted facility, or in local custody.
Arrests in New York and New Jersey
There is a perception that in states with more protective policies for immigrants, immigration detentions do not occur. It’s not like that. New York, Long Island, Newark, Jersey Metropolis, Elizabeth and Paterson continue to register operations and arrests related to immigration.
The difference is that the institutional journey may be different.
Other states where the search also tends to focus
Due to the size of the immigrant population and migratory activity, cases are also usually recorded in:
- Illinois: Focusing especially on Chicago and surrounding areas.
- Georgia: Especially in Atlanta and nearby counties.
- Arizona: Particularly Phoenix, Tucson and Yuma, due to their proximity to the border.
If ICE does not have your family member, they may be in another agency. This point is key: not every person missing after an arrest is automatically in ICE.
You may also be in the custody of:
- CBP: If you were detained near the border, airport or entry point.
- Local police or sheriff: If there was first an arrest for another reason.
- US Marshals: In specific federal processes.

What information should you gather before starting?
The more organized the search, the better. It helps to have on hand:
- Full neutral name.
- Birthdate.
- Country of birth.
- Number A if it exists.
- City where the arrest occurred.
- Approximate date.
- Any previous immigration document.
What to do if you manage to locate it
Finding it doesn’t solve everything, but it completely changes the picture. The first thing is to confirm which center you are in, if you can make calls, if they accept visits, which immigration court is handling the case and if you already have a hearing date.
In these cases, time matters. Especially if there is a risk of transfer or accelerated process.
