Effective April 11, 2025, certain foreign nationals in the US must register online with the Department of Homeland Security (DHS), while others are already registered based on their status. This requirement is based on a 1940 law that mandates every foreign national who is in the US for 30 days must be registered and fingerprinted and DHS issued an Interim Final Rule (IFR) to update the registration regulations, introducing a new online process for unregistered foreign nationals.
