U.S. President Donald Trump has ordered the temporary suspension of the Diversity Visa (DV) Lottery Program, commonly known as the Green Card Lottery. Homeland Security Secretary Kristi Noem announced the move on social media, confirming that the U.S. Citizenship and Immigration Services (USCIS) had been instructed to halt the program following Trump’s directive.

The decision follows a shooting incident at Brown University and MIT, where the suspect, Claudio Neves Valente, reportedly entered the United States through the DV program from Portugal and obtained permanent residency in 2017. Noem stated that such individuals should never have been allowed entry. The program annually grants up to 50,000 green cards to citizens of countries with low U.S. immigration rates. Nearly 20 million people had applied for the 2025 lottery.

The suspension is expected to face legal and political challenges in Congress, where lawmakers are divided over immigration policy. Analysts suggest the move could reignite debates on merit-based immigration and national security screening standards.
