If you have the person's A Number, call the 1-800 Immigration Court number, 1-800-898-7180 to see where the person's next Court hearing is scheduled. If it is scheduled for a Court located within a detention center, the person is likely detained there.
People in detention do usually have the ability to call family to notify them of their whereabouts in the system if the phone number they are calling can accept collect calls. But be aware that collect calls are usually very expensive. Whenever someone calls from detention, try to get as much information as possible about where they are AND especially their A number (the number assigned by ICE) and the number that is assigned to them by the jail where they are staying, sometimes called a booking number, cell number, bunk / barrack number or module number.
Immigration (ICE) usually transfers a person to a different place several times in the first few days of their detention. Why do they do that? Immigration officers take time analyze the person's case to determine what type of deportation process (there are many different types) is the process ICE is going to use to try to deport the person. Then they work to figure out where in the detention system there is a space available that matches the deportation process selected for the person. That space might be near where the person was detained, but it might be in a completely different part of the U.S. People caught by ICE in and around Los Angeles are regularly sent to immigration detention in other states, including Texas and Arizona.
There are several short-term immigration processing centers in and around Los Angeles where people are held with ICE determines where to send them long-term. One of them is called "B-18" in downtown Los Angeles. B-18 is a basement holding area inside the federal building that also houses many offices of the US Citizenship and Immigration Services, at:
300 N. Los Angeles St.
Los Angeles, CA 90012
A person held at "B-18" can be visited by family, friends or an attorney during visiting hours. The entrance to B-18 is not through the main doors at 300 N. Los Angeles, but rather through what looks like a loading dock ramp on the North side of the building (the face of the building to the left of the main entrance on Los Angeles St.).
If ICE believes a person has the right to have their deportation case decided by an Immigration Judge, the person will be sent to a long-term detention facility. The person will usually be told what the name of the detention facility is or the city in which it is located. The addresses and visiting policies of most detention centers nationally can be found on the Detention Watch Network's detention map. ICE-managed (not ICE contract facilities) facilities are listed here.
