U.S. pauses green card lottery after suspect in Brown and MIT attacks entered via program.

The U.S. has paused the Diversity Visa Program, commonly known as the green card lottery, following a shooting at Brown University and the killing of an MIT professor. Homeland Security Secretary Kristi Noem announced the suspension at President Donald Trump's direction, citing national security concerns linked to the suspect, Claudio Neves Valente, a Portuguese national who entered the U.S. through the program in 2017. The pause halts new applications and processing, affecting thousands of applicants worldwide, though current applicants and green card holders are not impacted. The administration says the decision is part of a broader review of immigration policy and public safety, but no timeline for resuming the program has been provided.
