US President Donald Trump has expanded a travel ban to include five additional countries, bringing the total to 17, citing deficiencies in immigration vetting processes as a primary concern. The newly banned countries are Burkina Faso, Mali, Niger, South Sudan, and Syria, with existing partial bans on Laos and Sierra Leone elevated to full restrictions. The measures aim to mitigate national security risks by addressing issues such as fraudulent documentation and lack of cooperation from foreign governments on law-enforcement data. Critics may view these policies as overly broad, while supporters argue they enhance security by prioritizing reliable information, reflecting Trump’s ongoing stance on immigration and international accountability.
