On June 4, 2025, President Donald Trump signed a new executive proclamation implementing a travel ban affecting nationals from 19 countries, citing national security concerns. The ban fully suspends entry for citizens of Afghanistan, Myanmar, Chad, Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen, due to deficiencies in vetting and screening processes, high visa overstay rates, or lack of cooperation in accepting back their nationals. Additionally, partial restrictions apply to nationals from Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela, with restrictions on certain visa categories and reduced visa validity. The policy emphasizes the importance of foreign governments' cooperation in information sharing and identity management to mitigate security risks. The proclamation also outlines exceptions, including lawful permanent residents, dual nationals traveling on non-designated passports, and individuals involved in major sporting events or specific visa categories. The move aims to prevent individuals who pose threats from entering the United States and to encourage diplomatic cooperation with targeted countries. This is a continuation of similar measures enacted during Trump's first term, with the new restrictions justified by ongoing deficiencies in foreign countries' security and vetting capabilities.
