A new travel ban by President Donald Trump could bar people from Afghanistan and Pakistan from entering the U.S. as soon as next week based on a government review of countries' security and vetting risks, three sources familiar with the matter said. The move harkens back to the Republican president's first term ban on travelers from seven majority-Muslim nations, a policy that went through several iterations before it was upheld by the Supreme Court in 2018. The new ban could affect tens of thousands of Afghans who have been cleared for resettlement in the U.S. as refugees or on Special Immigrant Visas because they are at risk of Taliban retribution for working for the U.S. during a 20-year war in their home country.
