The warning around the United States is straightforward and serious. The report says supporters have been told to keep their passport on them in case immigration officials ask for proof of legal entry and stay. One line in the guidance is especially clear: “Always carry a passport showing you have permission to enter or remain in the US.”
That matters because this tournament is spread across countries, not one host nation. Fans following England, Scotland or any travelling side may not just be moving between cities, but between legal jurisdictions. A missed document check could become more than an inconvenience. It could mean detention, disrupted travel and, in the worst case, missed matches.
The Mexico warning appears broader. The report says supporters have been advised to be alert to:
That is a reminder that major tournaments create opportunity away from the pitch as well as on it. Big crowds, unfamiliar cities and late-night celebrations can leave visiting fans exposed, especially those chasing cheaper routes and accommodation.
Modern World Cup support is about logistics as much as loyalty. Cross-border travel, entry stamps, hotel security and night-out choices are part of the matchday routine now. The romance of following your team remains, but the margin for error is thinner when the event stretches across North America.
The next thing to watch is how supporters adapt once group-stage travel becomes knockout-stage movement. If fans are likely to switch between the US and Mexico, preparation may prove almost as important as the ticket in your pocket.
