Restricting the Entry of Foreign Nationals To Protect the United States From Foreign Terrorists and Other National Security and Public Safety Threats

On June 4, 2025, President Donald Trump issued a proclamation to restrict the entry of foreign nationals from 19 countries deemed to pose national security or public safety threats to the United States. The proclamation fully suspends entry for nationals from 12 countries, including Afghanistan, Iran, and Libya, and partially suspends entry for seven others, such as Cuba and Venezuela, targeting both immigrants and nonimmigrants. This action, justified by deficiencies in these countries' vetting and information-sharing processes, may face legal challenges over its scope and implications for U.S. foreign relations, as it echoes previous travel bans upheld by the Supreme Court.
