ICE Detentions and Border Barriers Reach New Records in Trump's Second Term

Immigration enforcement has shifted from a border issue to a nationwide priority, marked by record detentions and expanded physical barriers. The administration argues these measures are delivering results, a stance tested by rising costs and shifting public opinion.

Under President Joe Biden, migrant encounters at the southern border exceeded 4.5 million between 2023 and 2024. By November 2025, streets in El Paso, Texas, that once hosted makeshift camps for thousands of migrants had gone quiet. The current administration froze asylum applications, ended catch and release practices, and deployed troops to the region. Homeland Security Secretary Markwayne Mullin stated on October 16 that strong enforcement works.

Construction efforts have accelerated with $46.5 billion in new funding from the One Big Beautiful spending bill. Before the current administration took office, approximately 644 miles of primary wall and 75 miles of secondary wall existed. Since then, 250 additional miles of barriers and detection technology have been completed. Another 1,443 miles remain under construction. Aaron Reichlin-Melnick of the American Immigration Council noted that crossings have not changed significantly since construction began in earnest, attributing the drop to policy and messaging. President Trump called himself the King of the Wall at a rally in Kentucky on October 17.

Domestic enforcement has intensified, with ICE detentions reaching a record of nearly 50,000 in July, according to the Deportation Data Project. A large share of those held had no criminal convictions, while detentions of immigrants with criminal histories fell to an all-time low of 27%. By mid-July, ICE removed an average of 1,255 people per day, up from about 770 in Biden’s final months. A two-month enforcement action in Minneapolis in early 2026, known as Operation Metro Surge, left two US citizens dead, unsettling some voters.

Polls released in late October showed 50% of voters trust Democrats on immigration, compared to 46% for Republicans. A separate poll found 31% of non-MAGA Republicans believe the campaign has become too aggressive. Refugee admissions have also dropped sharply, with 16,292 admitted so far in fiscal year 2026, of whom 16,287 were South African. Legal routes have narrowed, including a $100,000 fee on new H-1B visas introduced in September 2025, which caused 2027 registrations to fall by 40%.

Legal challenges have slowed some changes, with a court blocking the H-1B fee for now. The administration continues to push through new residency options, including the Trump Gold Card, which requires a $1 million gift and a $15,000 application fee. Only one applicant had been accepted by April 2026.
