A report by BBC Sport says concerns are growing ahead of the 2026 FIFA World Cup in the United States after referee Omar Artan, described as Africa’s top referee, is denied entry. The BBC links the incident to broader worries that some supporters, staff and officials could face difficulties when travelling and may be turned back at U.S. borders. The referee case is presented as a test of whether FIFA can manage its own tournament preparations and ensure that key personnel can participate as planned. The articles note that the World Cup is intended to bring together top players, coaches and officials from around the world, making access for match officials a critical operational issue. While the sources focus on the implications of Artan’s denial for FIFA’s control over World Cup logistics, they also place the case within a wider context of immigration and entry challenges for visitors to the United States for the tournament.
