US Immigration and Customs Enforcement, commonly known as ICE, has just signed an additional deal with Palantir Technologies worth $30m to track immigrants accused of violent crime, but also those who have overstayed their visas, Business Insider reported on Thursday.

Palantir’s expanded and refined surveillance tools are also meant to help ICE keep an eye on those who “self-deport”, which is something the Department of Homeland Security has been asking certain immigrants to do to avoid being forcibly - and sometimes very publicly - removed.

The new software, dubbed “ImmigrationOS” according to Business Insider’s review of the contract, will save “time and resource expenditure” when locating and arresting immigrants, and bring together all the data needed for “end to end immigration lifecycle from identification to removal”.
