ICE Has Not Served Court Notices to 233,000 Migrant Children

Summary

ICE transferred 448,820 unaccompanied children into federal custody from fiscal 2019 through 2023. Its own inspector general found the agency could not confirm workable release addresses for 31,322 of them. Separately, among children who crossed the border since January 2021, ICE had still not served notices to appear -- the filing that starts a child's immigration case and gives ICE a reason to check on them again -- on more than 233,000 as of January 2025. At one field office auditors visited, ten deportation officers split an average of 30,000 non-detained cases apiece.

From fiscal 2019 through 2023, U.S. Immigration and Customs Enforcement transferred 448,820 unaccompanied migrant children into the custody of the Department of Health and Human Services, which places most of them with sponsors while their immigration cases proceed. keeps legal responsibility for those cases after release -- but its own inspector general found the agency could not confirm workable release addresses for 31,322 of those children. A related, narrower count tells its own story: among children who crossed the border since January 2021, still had not served the court filing that starts an immigration case on more than 233,000 of them, as of January 2025. Auditors also found the officers responsible for these cases are stretched thin: at one field office, ten deportation officers split an average of 30,000 non-detained cases apiece, more than half of them unaccompanied children's cases alone.

Nearly half a million children, tens of thousands of dead-end addresses

Once Border Patrol apprehends an unaccompanied child, transfers custody to 's Office of Refugee Resettlement, which places the child in a shelter and, in most cases, with a sponsor -- typically a parent or relative already in the country -- while an immigration judge decides the case. keeps the legal file. Under a joint agreement between the two departments, 's shelter providers are supposed to send the child's discharge paperwork within 24 hours of release, including the sponsor's name, address, and phone number. DHS OIG found that address was blank, undeliverable, or missing an apartment number for 31,322 of the 448,820 children transferred to over the five-year period -- about 7% of them, by the report's own address-quality review of 's full dataset.

ICE's own review of its address data found 31,322 of the 448,820 children it transferred to HHS custody over five years had release addresses that were blank, undeliverable, or missing an apartment number -- about 7% of the total, and the baseline information ICE needs to know where a child is.

The bad addresses weren't abstractions. At one location auditors visited, officers estimated that addresses were wrong roughly 80% of the time; when the audit team went looking for two addresses where had released children most frequently, neither existed. had sent 34 children to those two addresses in fiscal 2023 alone. Separately, reported roughly 600 children as having fled its custody outright between fiscal 2019 and 2023 -- including one who ran five times in a single year, and another, wanted on an international arrest warrant for a killing in their home country, whom still had not located as of August 2024.

The filing that never came

A Notice to Appear is the document that formally starts a child's removal case and puts a court date on the calendar -- and, notes, gives a reason to check on the child again. As of January 2025, had not served one on more than 233,000 unaccompanied children who crossed the border on or after January 1, 2021. That is down from more than 291,000 unserved as of May 2024, after prioritized clearing the backlog -- but more than 49,000 of what remained, 21% of it, belonged to children who crossed in 2021 and still, four years later, have no court date.

ICE cut its backlog of unserved Notices to Appear for unaccompanied children by about 57,000 between May 2024 and January 2025 -- but more than 233,000 remained, and 49,000 of those (21%) belong to children who crossed the border in 2021 and still, as of the report, have no immigration court date. This population (children who crossed on or after Jan. 1, 2021) is narrower than the 448,820 total transferred since FY2019 shown elsewhere in this piece; the two figures are not directly comparable.

Serving the notice doesn't close the loop, either. OIG reported in August 2024 that more than 32,000 children who had been served notices failed to show up for their immigration hearings; by October 2024, that number had grown to more than 43,000, and lacked complete addresses for over 3,600 of them. Officials told auditors that children who miss court are considered at higher risk for trafficking, exploitation, or forced labor -- the same risks the monitoring system is supposed to catch.

Even as ICE served more Notices to Appear, the number of children who failed to show up for the resulting court date kept climbing -- from more than 32,000 as of August 2024 to more than 43,000 two months later, per ICE's own reporting to OIG.

One field office, ten officers, 300,000 cases

traced the breakdown partly to staffing. 's Enforcement and Removal Operations reported more than 1,000 deportation officers across 25 field offices responsible for monitoring over 7.5 million non-detained cases -- adults, families, and unaccompanied children combined -- as of September 2024. At one field office auditors visited, ten deportation officers were managing 300,000 non-detained cases as of February 2024: an average of 30,000 cases per officer per year, of which 17,000 -- 57% -- were unaccompanied children's cases alone. A previous audit found officers had, on average, just three minutes per case, per year, to spend on it. Nationwide, ERO had only 100 officers formally designated to coordinate unaccompanied-children's cases and issue notices to appear as of August 2024.

At one ICE field office OIG visited, 10 deportation officers together managed 300,000 non-detained immigration cases as of February 2024 -- an average of 30,000 cases per officer per year, more than half of them (17,000) unaccompanied-children's cases alone.

Beyond the paperwork, OIG found placed more than 14,500 children with unrelated sponsors or distant relatives in fiscal 2023, and more than 9,600 in fiscal 2024 -- among them three children released to spouses, one of whom was 40 years old. 's own referrals show why oversight matters here: it reported more than 570 incidents of suspected human, drug, or weapons trafficking involving unaccompanied children to 's Homeland Security Investigations unit between fiscal 2019 and 2023. Separately, data show roughly 600 children released to sponsors were later arrested in the United States as of October 2024 -- under 1% of everyone transferred, but, wrote, evidence of why consistent monitoring matters both for the children and for the communities they're released into.

  • The scale outran the system built to track it. moved 448,820 children into custody over five years while its own tools for confirming where they ended up -- discharge paperwork, sponsor addresses, court filings -- failed for tens of thousands of them at each step.
  • A four-year-old case can still have no court date. More than 49,000 children who crossed the border in 2021 have never been served a Notice to Appear, meaning no immigration court has ever been asked to decide their case.
  • 's promised fix is process and paperwork, not more officers, due by the end of September 2025. 's four recommendations -- clearer information-sharing with , a formal process for flagging bad addresses, a plan to clear the NTA backlog, and updated guidance for officers -- all carry the same target date, and none addresses the staffing shortage auditors identified as a root cause. None has yet been verified as complete.

This piece reports what 's audit team could verify through 's own records and interviews with field offices in Miami, Los Angeles, St. Paul, Philadelphia, San Diego, Baltimore, Houston, Dallas, New York, and Chicago; the audit did not have access to 's underlying case records, and some figures (the 233,000 unserved-notice count, in particular) cover only children who crossed the border on or after January 1, 2021 -- not the full 448,820 transferred since fiscal 2019 -- so the two totals should not be combined or compared directly. concurred with all four of 's recommendations and set a completion target of September 30, 2025; as of this report, had not yet verified that completed the corrective actions.
