Lead: President Donald Trump ordered a pause of the U.S. diversity visa (green card) lottery on Thursday, Dec. 19, 2025, after Portuguese national Claudio Neves Valente, 48, was identified as the suspect in shootings at Brown University and the Massachusetts Institute of Technology. Homeland Security Secretary Kristi Noem said she directed U.S. Citizenship and Immigration Services to halt the program, calling the suspect’s admission a failure of the system. Valente is accused of killing three people — two Brown students and an MIT professor — and wounding nine; officials said he was found dead from a self-inflicted gunshot wound the same day. The administration’s move immediately raised questions about legal challenges and the future of a congressionally created program that issues up to 50,000 visas annually.
Key Takeaways
- President Trump ordered a suspension of the diversity visa (green card lottery) on Dec. 19, 2025, after the suspect in the Brown and MIT shootings was reported to have entered the U.S. via the program.
- The suspect, Claudio Neves Valente, 48, was linked to shootings that killed two Brown students and an MIT professor and injured nine others; he was found dead by an apparent self-inflicted gunshot wound.
- The diversity visa program makes up to 50,000 immigrant visas available annually to applicants from underrepresented countries; nearly 20 million applied for the 2025 lottery.
- For the 2025 lottery cycle, roughly 131,000 people were selected when spouses and dependents are counted; Portuguese nationals received 38 slots.
- Valente first studied at Brown on a student visa beginning in 2000, took a leave of absence in 2001, and was issued a diversity immigrant visa in 2017, later obtaining lawful permanent resident status.
- The suspension is expected to prompt immediate litigation because the program was established by Congress and has statutory protections.
- Critics say the move continues an administration pattern of tightening legal immigration channels after high-profile violent incidents; supporters argue it is a necessary safety response.
Background
The Diversity Immigrant Visa Program, commonly called the green card lottery, was created by Congress to diversify immigration to the United States by awarding up to 50,000 immigrant visas each year to nationals of countries with low rates of immigration to the U.S. Historically, many winners have come from African countries and other underrepresented regions. Applicants enter electronically and winners are selected by random lottery; selected applicants then undergo consular interviews, medical checks and background vetting before receiving immigrant visas.
President Trump has been a long-time opponent of the diversity visa program, arguing it presents security risks and should be curtailed or ended. His administration has previously tightened immigration rules following violent incidents with foreign-born perpetrators, and this latest pause follows that pattern. Legal scholars note that because the program is established by statute, suspending it administratively is likely to trigger court challenges and congressional pushback.
Main Event
On Dec. 19, 2025, Homeland Security Secretary Kristi Noem posted on the social platform X that, at President Trump’s direction, U.S. Citizenship and Immigration Services (USCIS) would pause the diversity visa program. Noem said the suspect, identified by authorities as Portuguese national Claudio Neves Valente, should never have been allowed into the United States. Officials said Valente was found dead the same day from an apparently self-inflicted gunshot wound after the shootings at Brown University — which killed two students and injured nine — and the slaying of an MIT professor.
According to a Providence police affidavit cited in reporting, Valente had attended Brown University on a student visa beginning in 2000 and took a leave of absence in 2001. The affidavit states that Valente was issued a diversity immigrant visa in 2017 and obtained lawful permanent resident status months later. Reporting has not yet provided a continuous public record of Valente’s whereabouts between 2001 and his visa issuance in 2017.
The diversity visa program’s scale helps explain why the administration’s action has broad consequences: nearly 20 million people entered the 2025 lottery and roughly 131,000 individuals — counting spouses and dependents — were selected in that cycle. Portuguese citizens were allocated 38 slots in the 2025 lottery. After selection, winners undergo the same vetting and interviewing processes as other immigrant visa applicants before entering the United States as lawful permanent residents.
Analysis & Implications
Administratively pausing a congressionally established visa program raises immediate legal questions. The Diversity Visa Program was created by statute, and courts will be asked to weigh whether the executive branch has authority to suspend it without new legislation. Past litigation over immigration policy has moved quickly in federal courts; observers expect rapid filings from advocacy groups, immigrant-rights organizations and possibly state governments that view the pause as overreach.
Politically, the action reinforces themes the Trump administration has pursued since 2016: restricting legal immigration channels and framing policy changes around national security concerns after violent incidents. Supporters of the suspension will argue that it is a reasonable, precautionary measure aimed at preventing future attacks, while opponents will call it opportunistic and likely to harm lawful applicants who pass thorough vetting.
Operationally, USCIS and State Department consular posts will face immediate questions about processing, interview backlogs and what happens to winners already in the pipeline. Agencies must decide whether to freeze adjudications, delay scheduling of interviews, or allow already-scheduled processes to continue — choices that affect tens of thousands of applicants and consular workflows around the world.
Comparison & Data
| Metric | 2025 Lottery / Program Fact |
|---|---|
| Maximum visas available annually | 50,000 |
| Number of applicants for 2025 | Nearly 20,000,000 |
| Selected in 2025 (including spouses) | ~131,000 |
| Portuguese slots won in 2025 | 38 |
The dataset above underscores the program’s scale: a small fraction of entrants are selected, and final admission depends on subsequent vetting. The diversity visa has historically drawn millions of applicants because it provides a pathway to permanent residence from countries with low admission rates, but its random selection element and statutory cap mean policy shifts can affect a sizable population quickly. Any prolonged suspension would ripple through consular scheduling, immigrant legal services, and immigrant communities awaiting family reunification.
Reactions & Quotes
This heinous individual should never have been allowed in our country — at the president’s direction, I have ordered USCIS to pause the diversity visa program while we review the process.
Kristi Noem (Homeland Security Secretary)
Noem framed the pause as an immediate corrective step; DHS communications emphasized review of vetting procedures. Administration officials argue the pause is a safeguard while agencies reexamine how the lottery’s vetting intersected with long-term residency outcomes.
Suspending a program that Congress created raises separation-of-powers questions and will almost certainly prompt litigation.
Immigration law scholar (university)
Legal experts noted the statutory basis for the program and explained that courts will likely be asked to determine whether an executive suspension is lawful. Civil-rights and immigrant-rights groups have already signaled intent to challenge broad pauses that affect lawful applicants.
We mourn the victims and recognize the need for careful review, but a blanket halt penalizes tens of thousands of lawful applicants who passed vetting stages.
Immigrant advocacy organization (national NGO)
Advocates emphasized the human cost of administrative pauses, noting that selected winners often include families and applicants who completed significant portions of the application process and background checks.
Unconfirmed
- Any direct link between the lottery selection process and the suspect’s motives has not been established in public records and remains unproven.
- Public reports do not yet clarify the suspect’s movements or legal status between his 2001 leave of absence from Brown and issuance of a diversity visa in 2017.
- Whether the administration plans a long-term termination of the program or a temporary pause for procedural review has not been formally detailed beyond the announcement.
Bottom Line
The administration’s decision to pause the diversity visa program after the Brown and MIT shootings is a high-stakes policy move with legal, operational and political consequences. It responds to immediate security concerns cited by officials, but it also places a congressionally established program at the center of what will likely be swift court battles and contentious public debate.
For applicants and immigrant communities, the immediate impact is uncertainty: tens of thousands who entered or were selected in the 2025 cycle could face delays or administrative reversal. Observers should watch for rapid litigation filings, clarifying guidance from DHS and USCIS, and any congressional responses that could seek to protect or modify the program’s statutory status.
