On June 4, 2025, President Donald Trump signed a proclamation banning nationals from 12 countries, including Iran, Afghanistan, and Somalia, from entering the U.S. due to national security concerns. Partial restrictions were placed on seven more, like Cuba, Venezuela, and Laos. The ban takes effect on June 9.
Countries were flagged for issues like terrorism ties, high visa overstay rates, and refusal to repatriate deportees. Afghanistan has no central passport authority, while Myanmar and Chad showed visa overstay rates above 40%. Eritrea denies deportation requests, and Iran is labeled a state sponsor of terrorism.

The State Department updated North Korea’s travel advisory to “Level 4: Do Not Travel,” citing risks of arrest, detention, and no U.S. consular support. U.S. passports are not valid for travel to NK without special authorization.
Mexico remains a major concern, with six states under “Do Not Travel” orders due to cartel violence. Travelers are urged to follow state-by-state advisories, avoid night travel, and use secure transportation options.
