The Department of Homeland Security has issued a sweeping directive that will affect nearly every foreign national in the United States, including H-1B visa holders, international students, and even Green Card holders. Under a renewed enforcement of the Alien Registration Act, all noncitizens must now register with the federal government and carry proof of registration at all times—or face legal consequences.
In a statement Friday, DHS Secretary Kristi Noem said the Trump administration would no longer allow selective enforcement of immigration laws, warning immigrants that failing to register could result in fines, jail time, or both.
“President Trump and I have a clear message for those in our country illegally: leave now,” Noem said. “If you leave now, you may have the opportunity to return and enjoy our freedom and live the American dream. The Trump administration will enforce all our immigration laws—we will not pick and choose which laws we will enforce.”
The change stems from Executive Order 14159, Protecting the American People Against Invasion, signed by President Trump on January 20. The order calls for strict immigration enforcement and revives long-dormant provisions of the Alien Registration Act—first enacted in 1940—requiring all noncitizens who remain in the U.S. for more than 30 days to register with the government.
Who must register?
According to DHS, the following rules now apply:
-
All noncitizens who have been in the U.S. for more than 30 days (as of April 11, 2025) must register immediately through USCIS.
-
Noncitizens entering the U.S. after April 11 must register within 30 days of arrival.
-
Children turning 14 must re-register and submit fingerprints within 30 days of their birthday—even if previously registered.
-
Parents or guardians must register minor children who stay in the U.S. longer than 30 days.

Once registered and fingerprinted, immigrants will receive official documentation. All noncitizens age 18 or older are required to carry this proof at all times.
While the law itself isn’t new, its enforcement under this administration marks a significant shift. Previously, the registration requirement had rarely been enforced or publicly emphasized.
“This administration has directed DHS to prioritize enforcement,” Noem said. “There will be no sanctuary for noncompliance.”
