Executive Order 13769, titled 'Protecting the Nation from Foreign Terrorist Entry into the United States,' was signed by President Donald Trump on January 27, 2017. The order, often referred to as the 'Muslim Travel Ban,' temporarily suspended the entry of foreign nationals from seven Muslim-majority countries—Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen—for 90 days, halted the U.S. Refugee Admissions Program for 120 days, and indefinitely banned Syrian refugees. The stated purpose was to enhance national security by preventing the entry of individuals deemed to pose a terrorism risk. The order immediately sparked widespread protests, chaos at airports, and numerous legal challenges. It was subsequently superseded by Executive Order 13780 on March 6, 2017, and later by Presidential Proclamation 9645 on September 24, 2017, which established more permanent restrictions. The Supreme Court ultimately upheld the third iteration of the ban in Trump v. Hawaii in 2018. The policy was officially rescinded by President Joe Biden via Presidential Proclamation 10141 on January 20, 2021.
