Executive Order 13769, signed by President Donald Trump on January 27, 2017, aimed to restrict immigration from several countries. The order specifically targeted individuals from Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen, citing national security concerns. It temporarily suspended the U.S. refugee program and imposed a 90-day travel ban for citizens of these nations. The order faced significant legal challenges and public protests, leading to revisions and subsequent versions. Courts ruled against parts of the order, arguing it violated constitutional rights. Ultimately, the order sparked a national debate on immigration policy and security.
