On June 4, 2025, President Donald Trump signed a proclamation banning entry to the U.S. for nationals from 12 countries—Afghanistan, Myanmar, Chad, Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen—citing national security risks. Partial restrictions also apply to Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela.

The ban targets countries with issues such as high visa overstay rates, lack of cooperation on repatriation, weak or absent government control, terrorism concerns, and non-compliance with U.S. security protocols. Exceptions exist for certain visa holders and lawful permanent residents.

The restrictions take effect June 9, 2025, with a brief implementation period to avoid past confusion. The administration stressed the policy is conditional and may be lifted if countries improve cooperation.

Additionally, the U.S. Department of State updated travel advisories, placing North Korea on the highest “Do Not Travel” list, bringing total countries under this warning to 21 due to extreme safety risks. Several other nations were upgraded to “Reconsider Travel” due to crime, terrorism, and political unrest.

Mexico remains under a state-by-state advisory due to widespread violent crime and cartel activity, with six states under “Do Not Travel” guidance. Travelers are urged to exercise caution, avoid risky areas, and follow security recommendations.
