Most foreign tourists who plan to travel to Russia during the FIFA World Cup are from the US (fans pictured: Credit: US Department of State), a study has found, TASS reports. The ranking was based on the spurt in visitor arrivals to Russia from June 4 to July 15 when World Cup ticket holders do not need a visa to enter the country. The ForwardKeys data company, which predicts future travel patterns, ranked the US as No 1 followed by Brazil, Spain, Argentina, South Korea, Mexico, China, the UK, Germany and Egypt. The large contingent from the US has come as a surprise as the country did not qualify for 2018 World Cup. But the interest in football has grown in the US after the country hosted the 1994 World Cup.
