CERN has issued detailed mobility guidance for staff and visitors attending events on its Meyrin campus during the 12–18 June G7 summit, warning of “significant disruption” at local border crossings between France and Switzerland. From 11 June the Canton of Geneva began closing minor posts and introduced vehicle-checkpoint queues on the A1 motorway, with priority lanes available only to holders of special “macaron” passes. UK academics, diplomats and corporate observers travelling to summit-related side-events must now plan extra travel time and carry passports alongside CERN access badges. Shuttle services will operate but may be rerouted through tunnels subject to police checks. For travellers who still need assistance with last-minute visa documentation or passport renewal, VisaHQ’s UK portal (https://www.visahq.com/united-kingdom/) provides expedited processing, live status tracking and expert advice on Swiss entry requirements and Schengen transit rules, making it a useful resource amid the summit-week uncertainty. The measures illustrate how major political gatherings can abruptly alter Schengen-area mobility rules; Swiss authorities retain the right to impose identity controls despite the country’s association agreement. British travellers should note that the EuroAirport Basel–Mulhouse-Freiburg remains outside the affected zone, offering a possible alternative entry point. Mobility teams organising executive attendance should review insurance coverage for delay-related costs, pre-book flexible rail tickets via Paris or Lyon, and distribute real-time update channels such as the CERN Campus App. After 18 June controls will revert to normal, but further spot checks are possible while delegations depart.
