The administration of US President Donald Trump has announced it is suspending the diversity lottery immigrant visa program.
Secretary of Homeland Security Kristi Noem said on Thursday that at Trump's direction, she is immediately directing the US Citizenship and Immigration Services to pause the program.
Noem cited last Saturday's shooting at Brown University, which left two people dead and nine others injured. She noted that the suspect, a Portuguese national who was found dead, had received a green card through the program.
The scheme allocates up to 55,000 visas each year by lottery to people from countries with historically low rates of immigration to the US, granting winners permanent residency. Japan is among the countries eligible for the program.
Trump sought to end the program in 2017 during his first term as president, saying a suspect in a terror attack in New York had entered the US under the scheme.
Noem said that the suspension is "to ensure no more Americans are harmed" by what she described as the "disastrous program."
