New Alien Registration Rules Take Effect: What Noncitizens in the U.S. Need to Know
As of April 11, 2025, federal enforcement of alien registration laws has significantly intensified, affecting millions of noncitizens across the United States. Under the Alien Registration Act of 1940, any foreign national aged 14 or older who remains in the U.S. for 30 days or more must register and be fingerprinted. While the law has historically seen limited enforcement, the reinstated measures now require many individuals—including those without legal status—to complete a new online registration form (G-325R) and attend a biometrics appointment.
This update outlines who must register, what constitutes proof of registration, and the potential legal consequences for noncompliance. With DHS estimating that between 2.2 to 3.2 million people may be impacted, understanding these new requirements is critical for avoiding fines, detention, or removal proceedings.
