On June 4, 2025, President Donald Trump issued a proclamation banning nationals from 12 countries from entering the United States, citing national security risks and insufficient vetting processes. The countries facing full restrictions are Afghanistan, Myanmar (Burma), Chad, Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen. Partial entry restrictions have also been imposed on Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela. The ban takes effect on June 9 at 12:01 a.m. EDT and exempts lawful permanent residents, valid visa holders, and certain international sports teams. Trump linked the decision to a recent attack in Boulder, Colorado, by an Egyptian national, although Egypt was excluded from the list. The measure mirrors the controversial 2017 travel ban, which was upheld by the Supreme Court in 2018. The new policy has provoked strong international backlash, with several affected countries, including Venezuela, denouncing the move.
