WASHINGTON (Reuters) - The White House announced changes to the U.S. visa waiver program on Monday so that security officials can more closely screen travelers from 38 countries allowed to enter the United States without obtaining visas before they travel.
Under the new measures, which were prompted by the Nov. 13 attacks in Paris by Islamic State militants, the Department of Homeland Security would immediately start to collect more information from travelers about past visits to countries such as Syria and Iraq, the White House said.
The changes will "enhance our ability to thwart terrorist attempts to travel on lost or stolen passports," White House spokesman Josh Earnest told reporters in Paris, where President Barack Obama is attending U.N. talks on climate change.
