What’s the context?

Technological innovations like robots and biometric recognition are in expanding use in Trump's deportation campaign.

NEW HAVEN, Connecticut - From surveillance towers to facial recognition, the United States is relying heavily on advanced technologies to monitor and deport immigrants.

Artificial intelligence (AI) and other fast-developing innovations are proving to be powerful enforcement tools in the hard-line immigration campaign launched by President Donald Trump.

Many of these systems were implemented under previous administrations, including that of former Democratic President Joe Biden, but their growing use is raising privacy and due process objections from advocacy groups like the American Civil Liberties Union.

Below is a list of technologies the U.S. is using to escalate its immigration enforcement.

CBP Home phone app

In March, U.S. Customs and Border Protection (CBP) released a new version of CBP Home, an app for users to navigate the agency's approval processes.

The app has a new "self-deport" feature for undocumented immigrants to tell the government they are voluntarily leaving the country.

To self-deport, undocumented immigrants provide photos, their intended country of destination and confirmation they have enough money to depart.

AI predictions

Immigration and Customs Enforcement (ICE) uses AI in its "Alternative to Detention" operations, which allow some undocumented immigrants to stay in their communities, often under house arrest, while their cases are processed.

To keep track, the agency runs the Intensive Supervision Appearance Program (ISAP), which uses machine learning to assign a "Hurricane Score." The score helps determine how likely immigrants may flee or comply with the programme.

The score is used in deciding whether they can be exempt from detention and the conditions of their release.

ICE uses a similar tool known as Risk Classification Assessment (RCA) in making detainment decisions and evaluating flight risks of those arrested for immigration violations.

Under Biden, Department of Homeland Security (DHS) Secretary Alejandro Mayorkas said RCA was not powered by AI and merely automated risk calculations.

Looking ahead, the DHS 2025 budget includes $5 million "to support the growing adoption of AI across DHS."

GPS tracking

GPS-enabled tracking devices, such as ankle monitors and smart watches, are used to check the locations of those under ISAP surveillance.

ICE has also been giving undocumented immigrants smart phones with a SmartLINK app, which requires users to check in with their GPS coordinates.

Biometrics

DHS further surveils monitors immigrants using their identifiable physical features. For example, the SmartLINK app also requires immigrants to check in with selfies.

A facial recognition system matches the selfie to photographs on file to verify users' identities.

ISAP requires some people to check in by telephone, and a biometric recognition system compares the voice of the caller to an existing recording.

CBP additionally uses biological data. Federal law enforcement has been collecting DNA samples from immigrants at certain ports of entry. In 2022, CBP collected samples from about 37% of the 1.7 million people crossing U.S. borders.

Web scraping

State Department officials told Axios in March that it will be combing the internet to identify visa holders who support designated foreign terrorist organizations like Hamas.

This web scraping uses AI to analyse social media accounts of tens of thousands of student visa holders, who appear to be a primary target.

The measures are part of the "Catch and Revoke" programme launched to terminate visas of residents who allegedly harbour terrorist sympathies.

More than 1,500 international students have had visas revoked under the initiative, according to The New York Times.

The administration unexpectedly restored many of those student visas on Friday, but officials warned that they may be revoked again in the future.

Data sharing

The DHS has ramped up efforts to access various government databases to inform immigration enforcement.

The U.S. Treasury Department, Internal Revenue Service and DHS finalised an agreement under which certain taxpayer data is shared with authorities to help locate migrants.

Border sensors

CBP relies on patrolling technologies at the U.S.-Mexico border to detect illegal crossings.

Robotic dogs and drones relay video feeds from various vantage points, while thermal imaging, radar and ground sensors also enable remote observation.

Defence contractor Anduril, which designs monitoring equipment, has deployed more than 300 autonomous surveillance towers along the border, powered by AI systems that can analyse visual data to spot crossings.

According to Anduril, the towers provided 30% of U.S. surveillance coverage along the southern border as of 2024.

The DHS 2025 budget includes $127 million for investment in border security technology, including surveillance towers.
