Russia is preparing to launch a sweeping new system to monitor migrant workers, combining biometric registration, location tracking, and intensified police oversight.

Set to begin in September, the program marks the latest phase in the Kremlin's tightening grip on migration -- under the banner of national security and social order.

The initiative, passed by the State Duma last month, introduces what officials call an "experiment" in Moscow and the surrounding region, where the largest concentration of migrant workers resides.

Over the next four years, foreign nationals entering without a visa will be required to register in a government-run mobile application that tracks their geolocation in real time. Failure to transmit location data for more than three days could result in the migrant being placed on a special watchlist -- effectively a fast track to deportation.

Exempt from the program are minors, diplomats and their families, and citizens of Belarus. But for everyone else compliance will mean fingerprinting, biometric photos, proof of residence, and constant digital surveillance.
