Exclusive: The 'Dublin Dodge' Provides a Smooth Path to Britain for Dual Nationals
In a revelation that could ease travel woes for thousands, The Independent has uncovered a risk-free method for British citizens who hold dual nationality to enter the United Kingdom. Dubbed the "Dublin Dodge," this route involves flying to Dublin and crossing into the UK via Ireland, leveraging the Common Travel Area (CTA) to bypass the stringent electronic travel authorisation (ETA) requirements that have caused significant stress and expense since their mandatory introduction on 25 February 2026.
The ETA Dilemma for Dual Nationals
Since the ETA became compulsory for all non-British and Irish visitors, UK dual nationals have faced a bureaucratic nightmare. Ministers have warned that they cannot use an ETA on their foreign passport, forcing many to scramble for proof of British citizenship through a passport or a £589 "certificate of entitlement." This has particularly impacted the "dormant diaspora," including children born to British parents without UK passports and older expatriates with lapsed documents.
As a concession, the government allowed carriers to accept expired British passports from 1989 or later at their discretion, but this offers no certainty. Cases of stranded British teenagers abroad have been widely reported, highlighting the practical barriers at departure points rather than the border itself.
How the Dublin Dodge Works
The solution is straightforward: dual nationals with passports from EU or Schengen nations can fly freely to Dublin. From there, they can board a bus to Belfast, which runs about three times an hour and takes around two hours. Under the Good Friday Agreement, there are no frontier checks at the Ireland-Northern Ireland border, allowing British citizens to enter the UK legally.
Once in Belfast, travellers can proceed to Great Britain by ferry or air without needing a passport. For example, Aer Lingus Regional accepts bus passes, work IDs, or student cards for flights across the Irish Sea. Alternatively, ferries from Dublin to Holyhead allow various forms of photographic ID or birth certificates for minors.
Legal and Practical Considerations
Zeena Luchowa, a partner at Laura Devine Immigration, confirms that this method is not unlawful, as British citizens have an unqualified right to enter the UK. However, she cautions that ad hoc checks can still occur within the CTA, and obtaining a British passport remains the safest option. The Home Office declined to comment on "hypothetical routes," while Lord Hanson emphasised that ETAs aim to modernise border security.
Looking ahead, Ms Luchowa warns that the impending EU Etias system could create similar issues for Schengen travel, affecting dual nationals with UK and Schengen citizenship. For now, the Dublin Dodge offers a viable, rule-compliant alternative for those seeking to avoid ETA-related hurdles.
