Iran is moving its World Cup training base from Tucson to Tijuana, the president of the country’s soccer federation said Saturday, removing one of the final hurdles to its participation in this summer’s tournament.

Iran is scheduled to open World Cup play at SoFi Stadium, facing New Zealand on June 15. It will play Belgium in Inglewood six days later before finishing the group stage against Egypt in Seattle. But there had been questions over the Iranian team’s security in the U.S. after American and Israeli attacks on the country began nearly four months ago.

This World Cup will be the first in which a qualifying team will play in a host country with which it was at war. In March, shortly after the war began, Iranian officials began to question whether they should travel to the U.S. for the tournament — doubts that increased after President Trump posted on social media to say he did not believe it was appropriate for Iran to come “for their own life and safety.”

Because the World Cup is being shared with Mexico and Canada, Iran requested permission to move its base across the border, a request Mehdi Taj, president of the Iran Football Federation, said Saturday had been granted.

FIFA, the World Cup organizer, did not immediately confirm the move.

“All team base camps for the countries participating in the World Cup must be approved [by] FIFA,” Taj said in his statement obtained by the Associated Press. “Fortunately, following the requests we submitted and the meetings we held with FIFA and World Cup officials in Istanbul, as well as the webinar meeting we had yesterday in Tehran with the respected FIFA secretary general, our request to change the team’s base from the United States to Mexico was approved.”

Iran’s federation said moving the base camp will resolve potential visa issues since the team will enter the U.S. through Mexico. Taj said that the team “may even be able to travel to and from Mexico using Iran Air flights.”

Tijuana is about 50 minutes by air from Los Angeles International Airport, about 55 minutes quicker than a flight from Tucson. Iranians have been banned by the U.S. government from receiving visas to enter the U.S., although exceptions are to be made for athletes, coaches, and support personnel involved in the World Cup.
