The United States President Donald Trump has suspended the green card lottery, which allowed Claudio Neves Valente to come into the US.
Themomentng reports that Homeland Security Secretary Kristi Noem confirmed the development in a post on 𝕏.
Noem noted that it was at Trump’s direction that she gave the directive for the United States Citizenship and Immigration Services to pause the program.
Valente, who is originally from Portugal, is believed to be responsible for the shootings at Brown University and MIT.
The shootings left two students and nine others wounded.
Valente first arrived in the US with a student visa in 2000 and became a permanent resident 17 years later.
The 48-year-old has since been discovered dead from self-inflicted gunshot wounds.
“This heinous individual should never have been allowed in our country.
“Every year, at least 50,000 green cards are available to nationals around the world via the DV1 visa program,” Noem said.
Meanwhile, Trump has signed a new Proclamation on Tuesday, December 16, 2025, significantly expanding the list of countries facing travel restrictions to the United States as part of the administration’s policy to tighten entry standards.
The expansion introduces partial travel limitations on 15 additional countries, with a heavy focus on Africa, and imposes full restrictions on several more nations.
Nigeria, alongside 14 other countries, was added to the list of nations facing partial travel limitations.
The specific nature of “partial limitations,” as established in the administration’s earlier June 2025 ban, typically means a ban on all immigrant visas (which lead to lawful permanent residency, or a Green Card) and a ban on specific non-immigrant visas used for tourism, study, and exchange (B-1, B-2, F, M, and J visas).
The newly added countries are:
Angola
Antigua and Barbuda
Benin
Côte d’Ivoire
Dominica
Gabon
The Gambia
Malawi
Mauritania
Nigeria
Senegal
Tanzania
Tonga
Zambia
Zimbabwe
The Proclamation continues full restrictions on the original 12 high-risk countries: Afghanistan, Burma, Chad, Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen.
It also imposes full restrictions on five additional countries based on recent security analyses: Burkina Faso, Mali, Niger, South Sudan, and Syria, as well as individuals holding Palestinian-Authority-issued travel documents. Two countries previously under partial restrictions Laos and Sierra Leone are now subject to full restrictions. Meanwhile, partial restrictions remain for Burundi, Cuba, Togo, and Venezuela.
The Proclamation lifts nonimmigrant visa bans for Turkmenistan, citing improved cooperation with the U.S., while maintaining restrictions on immigrant visas for its nationals.
Exceptions are provided for lawful permanent residents, current visa holders, certain visa categories such as athletes and diplomats, and individuals whose entry serves U.S. national interests.
