US Immigration: Record Detentions and New Border Barriers

The Trump administration has implemented its most aggressive immigration enforcement measures since Donald Trump first campaigned on border security in 2015. With additional funding from Congress and a supportive Supreme Court, the executive branch has expanded physical barriers and increased interior arrests. These changes come as midterm elections approach, making immigration a central issue for voters.

At the southern border, the flow of migrants has dropped sharply compared to the Biden administration. In 2023 and 2024, authorities recorded more than 4.5 million encounters. Under current policies, asylum applications are effectively frozen, and the practice of releasing migrants after initial processing has ended. Homeland Security Secretary Markwayne Mullin stated on October 16 that strong enforcement works. A visit to El Paso, Texas, in November 2025 showed quiet streets where makeshift camps once housed thousands of people.

Physical infrastructure has also expanded due to $46.5 billion in new spending. Government data indicates that 250 miles of primary barriers and detection technology have been completed since Trump returned to office. Another 1,443 miles are currently under construction. While some experts note that much of this work involves upgrades rather than new builds, the total mileage has increased. Trump called himself the King of the Wall at a rally in Kentucky on October 17 and reiterated that Mexico pays for the structure.

Inside the United States, Immigration and Customs Enforcement has reached record levels of activity. The Deportation Data Project reports that ICE detained nearly 50,000 individuals in July. A large portion of those held had no criminal convictions. Detentions of immigrants with criminal histories fell to an all-time low of 27 percent that month. By mid-July, ICE removed an average of 1,255 people per day. This figure exceeds the average of 770 removals per day during the final months of the Biden presidency.

Public opinion has shifted in response to these tactics. A two-month enforcement operation in Minneapolis in early 2026 resulted in the deaths of two US citizens. A poll from The New York Times and Siena College released on October 21 found that 50 percent of voters trust Democrats more than Republicans on immigration. Another survey by Politico and Public First in late September showed that 31 percent of non-MAGA Republicans believe the enforcement campaign has become too aggressive.

Refugee admissions have also declined significantly. The administration suspended admissions shortly after Trump took office. In February, the process reopened narrowly for Afrikaners from South Africa. The fiscal 2026 cap was set at 7,500 and raised to 17,500 in May. State Department data shows that 16,292 refugees were admitted by late October, with 16,287 being from South Africa. This number is lower than the 60,000 admitted in fiscal 2023 and the 100,000 in 2024.

Legal entry routes have narrowed through new fees and vetting processes. A $100,000 fee on new H-1B visas was introduced in September 2025. Registrations for 2027 fell by 40 percent according to US Citizenship and Immigration Services. A court has temporarily blocked the fee, but the change appears to have deterred some employers. A new residency option, known as the Trump Gold Card, requires a $1 million gift to the government and a $15,000 application fee. Only one applicant had been accepted by April 2026.
