Key Facts

- What happened Police counted 286 foreigners crossing illegally in the north from January to August, down from 4,393.
- Biggest drop Colchane, a high Andes border town, fell from 4,087 detections to 85, a drop of 98%.

Chile’s illegal border crossings in the north fell 93% from January to August 2026, with 286 foreigners detected against 4,393 a year earlier. The figures come from the Policía de Investigaciones (PDI), Chile’s civilian investigative police, and the National Migration Service (Sermig), which runs visas.
The drop follows a hard-line border plan by President José Antonio Kast, a conservative who took office in March 2026. Security Minister Martín Arrau said on Monday 26 October 2026 that irregular entries are down about 86%, while a wider count shows a smaller fall.
Where Illegal Border Crossings Fell Most
Of the 286 foreigners detected, 191 were at Chacalluta, the road crossing near Arica on the Peruvian border, and 85 were at Colchane. The three smaller posts of Chungará, Ollagüe and Visviri logged 4, 4 and 2 cases.
Illegal border crossings at Colchane fell from 4,087 detections to 85, a drop of 97.9%. Carabineros, who patrol the border, counted 27,276 people entering the north illegally in 2022, then 20,014 in 2023, 23,449 in 2024 and 7,530 in 2025.
Immediate returns also fell, from 2,553 between March and August 2025 to 380 in 2026, with 332 of them at Colchane. Pablo Garay, the PDI’s chief of migration, said Bolivians were 69% of those returned, then Venezuelans at 20% and Colombians at 6.6%.
What Changed on the Border
Kast ordered the military presence on the northern border doubled and trenches dug to block informal paths. Alberto Soto, the president’s delegate for the north, said 26 kilometers (about 16 miles) of trench were finished by August, half the 2026 target.
Soto says the trenches and patrols work as a funnel that pushes crossers toward a few points where soldiers and police wait. Illegal border crossings were already falling before Kast, since the Carabineros count for 2025 was 68% below 2024.
Expulsions Rose as Entries Fell
From January to July 2026, 1,330 foreigners left Chile under expulsion orders, up 76% from 753 a year earlier. Charter flights carrying expelled people rose from 4 to 9 in the same period.
The PDI also logged 7,501 voluntary departures at border controls, 78% of them Venezuelan. Sermig presents these numbers as proof that its border plan works.
Why the Government Gives Different Percentages
The 93% counts only illegal border crossings detected in the north, while the government also cites an 86% fall for people detected at the border. A wider count of filed cases of entry through unofficial crossings fell only 33% from January to July, from 16,788 to 11,242.
That wider count includes people found in Chile in a given year who may have arrived long before. Two opposition lawmakers asked the government to publish its counting method, and one says the real fall is closer to one third.
What It Means for You
For a US reader who follows migration policy, Chile is an early test of a trench-and-troops border model in South America. The figures show fewer illegal border crossings detected, but not whether fewer people are trying to cross.
Venezuelans were the largest group among the voluntary departures, so the shift touches migration flows that reach other countries in the region. Our Kast profile and Southern Cone explainer give the wider picture.

What Is Not Known
The figures do not say how many people still cross without being detected, or whether migrants chose other routes or countries. They also do not show how much of the fall in illegal border crossings comes from the trenches and troops.
The PDI data for September and October are not yet public, so the 93% covers January to August only. The security minister’s 26 October statement gives a rounded fall of about 86%, without the period or the raw counts.
