That’s how many international visitors aren’t coming to the United States, resulting in billions of dollars in lost economic activity, according to the U.S. Travel Association. The drop comes as the U.S. recorded a 6 percent decline in foreign visitors last year, according to the World Travel and Tourism Council, even as global tourism rebounded. The slowdown has continued into this year, with inbound travel down 4.8 percent in January compared to a year earlier, including a sharp 28 percent plunge in visitors from Canada, typically the second-largest source of international tourists.
