BRUSSELS — Even before they face off tomorrow night in Seattle, Belgium and the the United States are already at loggerheads over America's birthday celebrations.

U.S. Ambassador to Belgium Bill White insisted that Brussels' historic Parc du Cinquantenaire was left spotless after his lavish festivities marking 250 years of American independence, as Belgian authorities probe whether fireworks damaged one of the capital’s historic buildings.

“We are in immediate contact with the Belgian company that was hired to coordinate all event logistics, including the fireworks company,” White wrote on X on Friday. He said the contractor would “remediate where it is required” and insisted that “Cinquantenaire has never looked any cleaner than it was the day after we cleaned up after our event,” posting photographs of the park looking immaculate.

More than 8,800 invited guests attended the June 28 celebration — one of the biggest diplomatic receptions ever staged in Brussels — organized by White, featuring a large fireworks display beneath the triumphal arch and a gala held in Cinquantenaire’s Royal Museum of Art and History building.

The ambassador’s response came after Flemish newspapers De Standaard and Het Nieuwsblad reported that Belgium’s Buildings Agency had opened an investigation into possible damage to the museum.

The Building Authority confirmed that “fireworks debris was found on the roof, and certain limited areas of the roof appear blackened” in a statement to POLITICO, adding that “analyses are still ongoing” before being able to comment on the scope of any repair work.

Belgian Buildings Minister Vanessa Matz has urged caution, saying investigators must first determine whether any damage was caused by the fireworks display or by the severe thunderstorm that swept across Brussels the previous night. The celebration reportedly cost around €5 million, with White raising the money from roughly 220 Belgian and American companies.

BRUSSELS — A growing number of soccer supporters say chaotic visa procedures are keeping them from attending World Cup matches in the United States.

One Belgian-Moroccan soccer fan, who was granted anonymity to discuss the issue without fear of repercussions, told POLITICO he thought he had secured tickets to Saturday’s Morocco vs. Brazil match through FIFA’s lottery system, booked flights to New York and applied for entry to the U.S.

That's when things began to go wrong.

The fan, who had previously traveled with an Electronic System for Travel Authorization (ESTA) — the online authorization system used by travelers from countries that don't need visas for short visits to the U.S. — said his application was approved on May 27, but abruptly revoked one week later.

“There was nothing mentioned except for travel not authorized,” he said. “That’s the whole frustrating situation — the opacity of the whole thing.”

His attempts to apply for a non-immigrant visa were fruitless. Ahead of the World Cup, the State Department launched an expedited process for some fans seeking visas to attend matches in the U.S., but the Belgian-Moroccan national said he was never able to access it because an initial appointment platform failed to register his payments.

That, in turn, made it impossible to book the mandatory interview at the U.S. Embassy in Brussels required before requesting an expedited appointment. He added that calls to the embassy went unanswered because they were automatically forwarded to an inactive Belgian number.

Other World Cup attendees have reported similar problems. Scottish musician Kenny Smith said his ESTA was revoked despite recent travel to the United States. Meanwhile, Somali referee Omar Abdulkadir Artan was recently denied entry to the country despite being selected to officiate at the tournament.

FIFA President Gianni Infantino on Wednesday acknowledged that the special World Cup visa system was “not working always, and with everyone.” Homeland Security Secretary Markwayne Mullin defended visa denials Thursday, citing security concerns.

A spokesperson for the Department of Homeland Security declined to say if dual nationals were more likely to have their applications revoked, but said ESTA applications are continuously vetted and approval “does not guarantee admission” to the U.S.

For the Belgian-Moroccan fan missing Saturday's match, the visa ordeal undermined the point of the tournament. “The whole experience of a World Cup is intended to bring people together,” he said. “Now actually being rejected for no reason, it actually has the opposite effect.”
