From 15:00 GMT today, the UK’s short transition period for nationals of Nauru expires, meaning citizens of the Pacific micro-state must hold a visa—rather than an Electronic Travel Authorisation—to enter or even transit air-side through the United Kingdom. The change, flagged in December to airlines via the Border Force Carrier Support Hub, aligns Nauru with other countries whose passports are not recognised for ETA purposes.
During the grace period, Nauruan passengers who had booked travel before 10 December 2025 could still board using an ETA, but carriers have been instructed that such bookings are no longer valid. Direct-airside-transit passengers are also affected; those without a visa will be denied boarding and may incur significant re-routing costs.

While the volume of Nauru traffic through the UK is small, the episode is a timely reminder that nationality-specific carve-outs can close with little notice. Airlines and global booking tools need up-to-date visa-rule libraries, and corporate travellers from multi-national teams should double-check documentation when itineraries involve the UK as a hub.
The Home Office has not provided a public rationale for the policy shift, but industry analysts note that Nauru has no resident UK diplomatic post, making document verification difficult. Travel managers should ensure any affected employees or visitors secure the appropriate visa before scheduling onward travel.
