In a sweeping national security decision, former President Donald Trump signed a proclamation on June 4, 2025, blocking entry to the U.S. from 12 countries and imposing partial restrictions on 7 others. The order, which goes into effect on June 9, cites threats like terrorism, visa overstays, and lack of cooperation from foreign governments. Countries affected include Afghanistan, Iran, Myanmar, and Somalia. Lawful U.S. residents and certain visa holders are exempt.

Each country faces different concerns. For example, Afghanistan has a high rate of student visa overstays and lacks a secure passport system. Myanmar, Chad, and the Republic of the Congo also struggle with passport security and have been uncooperative with deportations. Eritrea and Haiti were flagged for weak law enforcement and refusing to take back deported nationals.

Iran and Cuba are included for their ties to terrorism, while nations like Libya, Yemen, and Somalia are dealing with internal instability and weak governments. Venezuela and Turkmenistan were cited for failing to meet basic immigration requirements. The administration says the restrictions could be lifted if these countries improve cooperation—mirroring Trump’s controversial 2017 travel ban.

At the same time, the State Department has added North Korea to its Level 4 “Do Not Travel” list, warning Americans about the risk of arrest, detention, and lack of U.S. consular support. Other countries under similar advisories include Mexico and Uganda due to ongoing concerns about terrorism, crime, and civil unrest. Americans planning international trips are urged to stay updated and cautious.
