The sheer scale of staging a tournament across North America, with long-haul travel, differing tax regimes and significant operational demands, has prompted unease among some participating nations.

The governing body has indicated it is prepared to raise prize money and participation payments beyond already record levels, presenting the expanded World Cup as a vehicle for wider redistribution rather than simply a bigger payday for the strongest teams.

FIFA has rejected any change to the schedule, saying teams are expected to play as planned.

Visa access and travel restrictions are also expected to be closely watched.

Officials from the Palestinian Football Association were recently denied entry to Canada for a pre-congress meeting, underlining the practical obstacles that can arise when sport, border policy and international politics collide.

However, Palestinian association vice president Susan Shalabi and president Jibril Rajoub have both now been granted visas and are expected to attend the congress, FIFA told Reuters on Monday.

Shalabi has already arrived in Vancouver while Rajoub is expected on Tuesday.

FIFA says it is working with host governments to help facilitate access for delegations, although the final list of attending associations will not be confirmed until the congress begins.

The wider logistics of the 2026 World Cup remain a defining theme. A tournament spread across three countries, multiple time zones and vast distances will test teams, supporters, broadcasters and organisers in ways no previous World Cup has.
