In a major national security move, President Donald Trump signed a proclamation on June 4, 2025, banning entry from 12 countries and placing partial restrictions on 7 others. The order cites terrorism, overstay rates, and lack of cooperation from foreign governments. Affected nations include Afghanistan, Iran, Myanmar, and Somalia. Exceptions are made for lawful residents and some visa holders.

Each banned country faces specific concerns. Afghanistan has high student visa overstay rates and no secure passport system. Myanmar, Chad, and the Republic of the Congo report similar issues, including non-cooperation with deportations. Eritrea and Haiti lack reliable law enforcement and refuse to repatriate citizens.
