THIS WEEK IN BRIEF:
THE FULL UPDATE:
CBP publishes fiscal 2025 border and migration data
Customs and Border Protection (CBP) published data on October 24 about border security and migration through September 2025, the last month of the 2025 fiscal year.
Fewest Border Patrol apprehensions since 1970
The agency reported that its Border Patrol component apprehended 237,538 undocumented migrants between the U.S.-Mexico border’s ports of entry during fiscal 2025. That is the smallest apprehension total since 1970 (201,780), and 76 percent of it occurred during the fiscal year’s first four months, from October 2024 to January 2025, when Joe Biden was still president.

Adding 206,133 people who came to the border’s ports of entry—87 percent of them during the Biden administration, when the “CBP One” app allowed appointments at the ports—makes a CBP-wide total of 443,671 encounters with migrants at the border in fiscal 2025.
The sharp drop in CBP encounters (a 79 percent decrease from fiscal 2024) owes to the Trump administration’s severely restrictive policies, especially the suspension of nearly all humanitarian reception of people fleeing danger. In January, the White House suspended access to the U.S. asylum system, a move that continues to face legal challenges, and has now gone five months without a single encountered migrant being released into the U.S. interior to pursue a claim outside of detention. The administration’s ongoing “mass deportation” campaign has meanwhile fed a climate of fear in the U.S. interior that discourages would-be migrants from considering the United States to be a destination. A softening U.S. job market could be a third factor.
Despite that overall trend, Border Patrol’s apprehensions appear to have bottomed out in July and have stopped decreasing. The agency’s 8,386 apprehensions in September were 83 percent more than in July (4,592).

It is not yet clear whether the increase is a trend that is likely to continue, or whether it is a reversion to a seasonal pattern of greater migration in the spring and fall when border-area weather is milder. Asylum-seeking migrants did not follow this seasonal pattern as closely, but the Trump administration’s ban means that they are not a significant part of the population currently encountered at the border.
Sectors
Border Patrol divides the U.S. border into nine geographic sectors; the growth since July has principally taken place in its Arizona and southern Texas sectors.

Tucson (Arizona) led all of Border Patrol’s sectors in migrant apprehensions in September, for the first time since May 2024.

Demographics
Just 33 percent of Border Patrol’s apprehensions were of family units (parents with children) or unaccompanied children; that is the smallest share for a non-pandemic year since 2015. From February to September, the Trump administration’s first full eight months, the child-and-family share dropped to 17 percent (7.5% families, 9.8% unaccompanied children).

Since July, though, “family unit members” have seen by far the largest growth, among demographic categories, in Border Patrol’s apprehensions. Arrivals of parents with children increased 210 percent (from 316 to 979 apprehensions) over a two-month period.

More than half of those family-unit apprehensions occurred in Arizona (Border Patrol’s Tucson and Yuma sectors), increasing from 47 in July to 521 in September.

Nationalities
Of all migrants entering U.S. custody at the border (Border Patrol apprehensions plus port-of-entry encounters) in fiscal 2025, 40 percent were citizens of Mexico, up from 34 percent during 2020-2024. During February-September, the full months when the Trump administration was in place, Mexico’s share rose to 75 percent of a much smaller total.

“Right now we’re back to what I would call old-school norms on the border, where the majority of people we’re arresting are from the country of Mexico,” CBP Commissioner Rodney Scott told The American Conservative. “The exotics, the countries with a very high threat for terrorism around the world, have all dropped off.”
Ports of entry
At the land border’s ports of entry, CBP’s recorded encounters with migrants plummeted the moment that the Trump administration canceled use of the CBP One smartphone app to make appointments. The CBP Office of Field Operations averaged 48,860 encounters per month during the last eight full months of the Biden administration, and 3,463 (93% fewer) during the first eight full months of the Trump administration.

Elsewhere in the hemisphere
During the first eight full months of the Trump administration, Mexico’s encounters with non-Mexican migrants dropped 91 percent compared to the last eight full months of the Biden administration, falling from 769,507 to 70,910 encounters.

Doctors Without Borders (MSF) published a dispatch from Tapachula, Chiapas, a city near Mexico’s southern border with Guatemala. There, because of the Trump administration’s crackdown on migration and suspension of asylum, “thousands of stranded migrants and asylum seekers” continue to live “in increasingly precarious conditions.” MSF’s facility in Tapachula has provided 128 percent more medical consultations and 53 percent more mental health consultations than it did in 2024.
In Panama, where migration through the Darién Gap has stalled to nearly nothing, the number of migrants registeredcrossing the treacherous jungle region totaled 753 during the Trump administration’s first full eight months, down 99.5 percent from 162,936 during the final eight full months of the Biden administration.
Instead, some migrants have given up on seeking protection or opportunity in the United States. The latest report from Colombia’s migration agency counted 17,701 migrants, mostly Venezuelan citizens, detected traveling southbound from Panama since February 1. The number of southbound migrants in September (1,200) was less than half of what it was in May (2,654), indicating that this flow is easing. Those who plan to abandon the northward journey and return to South America are fewer in number than they were earlier in the year.
A drop in fentanyl seizures at the border
CBP’s September data also include the agency’s seizures of illicit drugs along the U.S.-Mexico border. WOLA’s next weekly Border Update will cover these trends, but it is worth noting that border seizures of fentanyl dropped 46 percent from fiscal 2024 to 2025. The drop, which may indicate a decline in overall cross-border flows, began in mid-2023, well before Donald Trump took office.

Regional ICE directors purged, some replaced with Border Patrol agents
Over the October 25-26 weekend, according to several media reports, the Trump administration relieved at least a dozendirectors of Immigration and Customs Enforcement’s (ICE) 25 field offices of their command, including those in Denver, Los Angeles, Philadelphia, Phoenix, and San Diego. In a significant but still unclear number of cases—at least half, according to NBC News—they are to be replaced with hand-picked Border Patrol agents.
According to several reports, including those linked from this narrative, the White House is unhappy with ICE’s operational pace. In May, President Trump’s deputy chief of staff, Stephen Miller, demanded that ICE increase its interior U.S. arrests to 3,000 per day. The agency has rarely hit 2,000; 21 days into September, it had totaled 21,293 “book-ins” for the month, according to a regular report that has not been updated due to the government shutdown.
The administration is instead turning to Border Patrol, an agency idled at the border by the reduced migration levels discussed above, which has broad authorities to enforce immigration law in the U.S. interior, especially within 100 miles of any coast or international border. Border Patrol already has 1,500 of its 19,000 agents deployed in at least 27 U.S. cities.
Chief Bovino’s role
NBC reported that the list of officials replacing the purged ICE directors has been compiled by Corey Lewandoski, a onetime Trump campaign manager now acting as a “special advisor” to Department of Homeland Security (DHS) Secretary Kristi Noem, together with Gregory Bovino, the controversial and publicity-seeking “at large” commander of DHS operations in Chicago and previously in Los Angeles.
Though he started 2025 as the chief of the agency’s relatively quiet El Centro (California) sector, Bovino is now outside of Border Patrol’s chain of command: an unnamed law enforcement official told NBC that “Bovino does not report to the chief of Border Patrol or CBP’s commissioner, as other Border Patrol sector chiefs do,” he “reports directly to Noem.”
Having “brought militarized operations once primarily used at the border into America’s largest cities,” as the Los Angeles Times put it, Bovino “is not viewed as the exception to the norm, but the new standard for what is to come at ICE,” an unnamed official told the Washington Examiner.
Morale
The moves indicate that Border Patrol has the upper hand in a growing inter-agency rivalry. “ICE employees are not happy about any of it, feeling replaced and exhausted from the past nine months. Meanwhile, Border Patrol agents are ecstatic,” four sources told the Washington Examiner. One of those sources said that border agents are “eager” to carry out ICE’s internal duties because “the perception is that they [ICE] are always dragging their feet. They weren’t good team players.”
Meanwhile, morale at ICE “is declining due to the infusion of outside employees and leaders,” the Examiner added. “They are under constant threat; people are ground down; it’s a culture of fear” at ICE, Claire Trickler-McNulty, a Biden-era senior ICE official, told the New York Times.
Border Patrol’s harder organizational culture
White House officials like Miller are fond of Border Patrol’s more “cowboy” tactics like rappelling from helicopters in an alarmingly violent raid of a Chicago apartment building or chasing day laborers around Home Depot parking lots, officials told NBC News.
Indeed, many of the more controversial videos of masked agents’ aggressive and confrontational arrest and crowd control tactics in Los Angeles, Chicago, and elsewhere show those agents wearing dark green Border Patrol uniforms. Dan Altman, who headed CBP’s Office of Professional Responsibility during the Biden administration, explained to the Los Angeles Times that while ICE agents “lean heavily on investigations and typically know when they set out for the day who they are targeting,” Border Patrol is accustomed to patrolling the borderlands and confronting anyone whom they suspect of being undocumented.
With the leadership changes, more interior U.S. cities will likely see the aggressive tactics that Border Patrol has brought to Los Angeles and Chicago. While that is likely to cause more of a public outcry, unnamed officials tell conservative media outlets, it may not benefit the administration’s “mass deportation” campaign. “Border Patrol just comes in more heavy-handed. They don’t make more arrests, but they make more headlines,” a source told the Washington Examiner. “Since Border Patrol came to LA in June, we’ve lost our focus, going too hard, too fast, with limited prioritization,” a senior DHS official said to Fox News. “It’s getting numbers, but at what cost?”
Cybersecurity and civil liberties issues
AI-driven military databases in use at the border
“We’ve really evolved with operations on the border” in the “use of AI, big data, and networks,” the U.S. Army’s chief data and analytics officer, David Markowitz, told Breaking Defense. Though the Army and U.S. Northern Command, the Defense Department unit responsible for all services’ military activities in North America, have different mandates and legal authorities, “they both manage masses of data using AI software from the same contractor, Palantir.”
This lets Army personnel assigned to the Trump administration’s border mission, an unusual internal role for the military, integrate their databases with “Maven Smart,” a Palantir AI product for Northern Command that “integrates things the Army could never legally have access to, like law enforcement data, Homeland Security information, things we can’t touch, but by their joint command [authorities], with their relationships, they can.”
Facial recognition
On the streets of U.S. cities, ICE and CBP agents are using facial recognition technology to verify individuals’ U.S. citizenship, 404 Media reported. Videos of interactions with agents show them pointing their phone cameras at people, “in stops that seem to have little justification beyond the color of someone’s skin, to then look up more information on that person, including their identity and potentially their immigration status. It is not clear which specific app the officers in the videos are using.”
Services that can query personal data include an app called Mobile Fortify and datasets run by LexisNexis, Clearview AI, and others. If Mobile Fortify facially identifies someone as a noncitizen, even other evidence like a birth certificate may not be enough to prevent their detention.
AI surveillance trucks
Wired reporter Dell Cameron revealed that DHS has published a pre-solicitation notice for another big domestic surveillance project made possible with funding from the “big bill” that Congress passed in July. The Department seeks contractors to support “a Modular Mobile Surveillance System, or M2S2.”
This would allow Border Patrol agents to park four-wheel-drive vehicles, raise a telescoping mast equipped with AI, radar, high-powered cameras, and wireless networking. These could detect motion several miles away, distinguishing between people, animals, and vehicles, using “computer vision” algorithms originally developed for military drones.
Phone searches
Also at Wired, Cameron and Matt Burgess reviewed fiscal year-end CBP data and found a 17 percent increase, from fiscal 2024 to 2025, in CBP’s searches of individuals’ mobile devices. Agents and officers conducted approximately 55,424 searches at all nationwide ports of entry in 2025, up from 46,958 the previous year. (“All nationwide ports of entry” includes the Canadian border, airports, and other sites not along the U.S.-Mexico border.)
The record 2025 total includes simple searches—an agent scrolling through an individual’s unlocked phone, laptop, or similar device—and more advanced searches using tools to copy and analyze devices’ contents. “Advanced” searches totaled 4,363 in 2025. Border personnel have “broad powers” to search electronic devices without warrants, raising concerns about privacy and civil liberties violations, Cameron and Burgess noted.
“Smart wall” surveillance
While the Trump administration does not plan to build new barriers in Big Bend National Park, an ecologically important and very remote area of west Texas where illegal crossings are relatively rare, it does plan to implement new surveillance technologies in the region, the Houston Chronicle reported.
The administration’s wall-building plans, supported by a $46.5 billion allocation in the giant funding bill that passed in July, would leave about 536 of the U.S.-Mexico border’s 1,970 miles without a physical barrier but with new “detection technology” installed. This includes “camera, sensors, and radar instead of traditional fencing in difficult terrain,” the Chronicle noted.
The area without barriers appears to include 363 miles of Border Patrol’s Big Bend Sector, the quietest of the nine geographic sectors into which the agency divides the border. One percent of Border Patrol’s southern-border migrant apprehensions occurred in the Big Bend Sector between 2020 and 2025.
Instagram ruse to seek ICE-spotting accounts
404 Media reported that DHS is seeking to compel Meta, the company that owns Facebook, Instagram, Threads, and WhatsApp, to reveal the identities behind social media accounts that post about ICE activity. The Department is arguing that Meta must shut down an account posting about ICE activities in Montgomery County, Pennsylvania, because it is purportedly violating a customs law about the “importation of merchandise.” 404 noted that ACLU “lawyers fighting the case say the move is ‘wildly outside the scope of statutory authority.’”
