President Trump has ordered the Department of Homeland Security to pause the Diversity Immigrant Visa program after officials revealed the suspect in the deadly Brown University shooting entered the United States through the controversial lottery system.
The directive comes as authorities piece together details about Claudio Manuel Neves Valente, the 48-year-old Portuguese national suspected of killing two Brown University students and wounding nine others before apparently taking his own life. Investigators have also linked Valente to the killing of an MIT professor in a shocking spree of campus violence.
From Lottery Winner to Murder Suspect
“The Brown University shooter, Claudio Manuel Neves Valente entered the United States through the diversity lottery immigrant visa program (DV1) in 2017 and was granted a green card. This heinous individual should never have been allowed in our country,” Trump stated in his order to pause the program.
Valente, a former Brown student, was discovered dead Thursday evening in a New Hampshire storage facility from what appears to be a self-inflicted gunshot wound. “Claudio Manuel Neves Valente, 48, a Portuguese national and a former Brown student, was found dead on Thursday evening from a self-inflicted gunshot wound,” Providence Police Chief Oscar Perez confirmed at a news conference. Authorities found two firearms on Valente’s body.
The case has reignited debate about the Diversity Visa program, which has long been a political lightning rod. But what exactly is this immigration pathway that’s now under intense scrutiny?
Understanding the Diversity Visa Program
The program, often called the “green card lottery,” makes up to 50,000 immigrant visas available annually to people from countries with historically low rates of immigration to the United States. Competition is fierce — nearly 20 million people applied for the 2025 lottery, with more than 131,000 selected when including spouses and family members, according to immigration records.
Critics have long argued the program lacks sufficient security screening, while defenders maintain that lottery winners undergo the same vetting as other immigrants. The program’s random selection process has been both praised for democratizing immigration opportunities and criticized for its seemingly arbitrary nature.
The Brown University shooting has left campus communities across New England reeling. Parents and students gathered for vigils over the weekend, while security has been visibly enhanced at universities nationwide.
“We’re still learning what motivated this horrific act,” said one Brown administrator who requested anonymity because they weren’t authorized to speak publicly. “Our focus now is supporting our students and healing as a community.”
Whether the pause on the diversity visa program becomes permanent remains to be seen. Immigration experts note that previous attempts to eliminate the program have failed to gain sufficient congressional support, though this tragedy may shift the political calculus.
