As the Electronic Travel Authorisation regime beds in, an unexpected cohort has been caught in the cross-fire: British citizens who travel on a second passport. A detailed industry briefing circulated on 27 February highlights that, under long-standing provisions of the Immigration Act 1971, British nationals cannot be granted an ETA or any other form of ‘permission to travel’. From 25 February, carriers’ new pre-departure checks automatically reject dual nationals who try to rely on their non-UK passport—unless the document contains a Certificate of Entitlement to the Right of Abode or the traveller can show a current British passport. The change is not a new law but the result of full technological enforcement of an old rule. Airlines, whose systems were updated this week, report scores of dual nationals arriving at check-in unaware that their routine practice of travelling on, say, a Canadian or French passport with an ETA is now impossible. The Home Office rejected calls from MPs and the3million campaign group for a grace period, insisting that the information has been on GOV.UK for months. Yet immigration lawyers say they have handled multiple family-emergency cases where travellers were forced to cancel flights at the last minute. Obtaining the alternative Certificate of Entitlement costs £589 and currently takes up to eight weeks—well beyond the lead-time for many urgent trips.

If you are unsure which documents you need or how to secure them quickly, VisaHQ can help. Its dedicated United Kingdom portal (https://www.visahq.com/united-kingdom/) allows individuals and mobility teams to verify entry requirements, arrange fast-track passport renewals and apply for Certificates of Entitlement or other travel documents, simplifying the process when time is tight.
In a temporary concession, the Home Office has told carriers they ‘may’ accept an expired British passport (issued 1989 or later) alongside the foreign document if the biographical details match, but the decision remains at the airline’s commercial discretion and does not override the legal requirement. For corporate mobility teams the advice is stark: audit your UK-national employee populations for dual-passport users immediately. Staff travelling at short notice for client work or family reasons should prioritise fast-track British-passport renewal, even if they rarely use it, to avoid being stranded abroad. Travel policies should now list a valid UK passport as mandatory ID for any British citizen returning to the UK—no exceptions. Longer term, the episode illustrates a key risk in the shift to fully digital borders: when enforcement switches on, legacy habits can become liabilities overnight. Multinational employers need to map hidden edge cases—dual nationality, route-specific carrier rules, visa-switch timings—before technology makes them immovable operational roadblocks.
