A US immigration enforcement program that tracks nearly 200,000 migrants is collecting far more data on the people it surveils than officials previously shared, and storing that data for far longer than was previously known, the Guardian can reveal.

Newly released documents show that the US Immigration and Customs Enforcement Agency (Ice) stores some personal information the program collects on migrants through smartphone apps, ankle monitors and smartwatches for up to 75 years.
