WASHINGTON, DC – Today, U.S. Senator Mazie K. Hirono (D-HI) joined Senator Ed Markey (D-MA) and seven colleagues in sending a letter to U.S. Citizenship and Immigration Services (USCIS) senior official Kika Scott to express strong disapproval of the Trump administration’s resurrection of the requirement that immigrants must register with the federal government and carry proof of their registration at all times.
In the letter, the lawmakers write, “The Administration has explicitly linked this revived registration requirement to enforcement efforts, empowering federal prosecutors to target immigrants who fail to comply. This creates a perilous dilemma for immigrants who entered the country without inspection and have had no prior contact with federal authorities. Those who register risk exposing themselves to removal proceedings, while those who refrain from registering face the threat of criminal prosecution. The policy further jeopardizes millions of immigrants—including those with lawful status—by subjecting them to penalties for simply failing to carry proof of registration.”
The lawmakers continue, “This registration policy echoes historical precedents that have been widely discredited and condemned. The Alien Registration Act of 1940 was initially implemented during World War II in a climate of fear and xenophobia, requiring noncitizens to register at post offices across the country. Now, by dusting off and weaponizing an outdated law, the Trump administration is reviving a dangerous precedent that will undermine fundamental civil liberties, disproportionately burden immigrant communities and millions of mixed-status families, and transform America into a ‘carry your papers’ country.”
The lawmakers request answers by April 8, 2025, to questions including:
In addition to Senators Hirono and Markey, the letter was signed by Senators Dick Durbin (D-IL), Alex Padilla (D-CA), Elizabeth Warren (D-MA), Ron Wyden (D-OR), Cory Booker (D-NJ), Tammy Duckworth (D-IL), and Bernie Sanders (I-VT).
The full text of the letter is available here and below.
Dear Ms. Scott:
The Trump administration will soon resurrect one of the most draconian and discriminatory immigration policies in our nation’s history, forcing immigrants to register with the federal government and carry proof of their registration at all times. Bringing back this long-dormant policy is the latest salvo in the Administration’s unrelenting campaign to demonize and criminalize immigrants, treating them as threats rather than as individuals seeking opportunity and safety. By reviving a World War II-era registration law, the Administration would take us back to some of the darkest periods of our history, evoking policies that have been widely condemned for their inhumane and immoral treatment of noncitizens. The implications of this measure—both in terms of enforcement and its effect on immigrant communities—are profound, unjust, and unacceptable.
Following up on President Trump’s day-one executive order on immigration inaccurately entitled Protecting the American People Against Invasion, 1 U.S. Citizenship and Immigration Services (USCIS) has announced that it will soon reinstate an antiquated requirement that all immigrants who did not enter the United States with a visa must register with the federal government and carry proof of their registration at all times. This provision, originally part of the Alien Registration Act of 1940, had long been rendered obsolete by subsequent immigration policies and practices. Under the new directive, USCIS will develop a registration process for affected individuals, who will then be required to submit a form confirming their presence in the United States. Those who fail to register or fail to carry proof of registration will face criminal prosecution under federal law.
The Administration has explicitly linked this revived registration requirement to enforcement efforts, empowering federal prosecutors to target immigrants who fail to comply. This creates a perilous dilemma for immigrants who entered the country without inspection and have had no prior contact with federal authorities. Those who register risk exposing themselves to removal proceedings, while those who refrain from registering face the threat of criminal prosecution. The policy further jeopardizes millions of immigrants—including those with lawful status—by subjecting them to penalties for simply failing to carry proof of registration. Any registration requirement should, at a minimum, present immigrants with a path forward to legal status, like the 1986 Immigration Control and Reform Act did. This legislation led to almost 3 million undocumented immigrants gaining legal status, many of whom ultimately became U.S. citizens.
This registration policy echoes historical precedents that have been widely discredited and condemned. The Alien Registration Act of 1940 was initially implemented during World War II in a climate of fear and xenophobia, requiring noncitizens to register at post offices across the country.6 Over time, the policy was integrated into routine immigration procedures, making separate registration requirements obsolete. More recently, in the wake of 9/11, the Bush administration’s National Security Entry-Exit Registration System (NSEERS) disproportionately targeted Muslim noncitizens, subjecting them to heightened surveillance and leading to mass deportations. That program was widely criticized for its discriminatory impact and ineffectiveness—having failed to produce a single terrorism conviction—and was ultimately dismantled. Now, by dusting off and weaponizing an outdated law, the Trump administration is reviving a dangerous precedent that will undermine fundamental civil liberties, disproportionately burden immigrant communities and millions of mixed-status families, and transform America into a “carry your papers” country.
To help us better understand how the Administration intends to implement and enforce its registration policy, please respond in writing by April 8, 2025 to the following questions:
The Trump administration’s decision to enforce this archaic law is a regressive and indefensible move that will have lasting consequences for immigrant communities and the integrity of our immigration system. We urge USCIS to immediately reconsider this misguided policy and provide Congress with a full accounting of its intended implementation and enforcement. We will continue to exercise rigorous oversight to ensure that immigrant communities are not subjected to unnecessary and punitive measures that undermine their rights and dignity.
Sincerely,
###
