UK's New ETA System Creates Headaches for Dual Citizens

A significant change to UK border rules takes effect this week, catching some travelers off guard. The Electronic Travel Authorisation (ETA) system, now mandatory for visitors from 85 visa-exempt nations including the United States and Australia, is designed to pre-screen travelers. While the government touts it as a modernization of border security, it has created an unexpected bind for one group: British dual nationals.

For these individuals, holding citizenship in both the UK and another country, the new rules present a stark choice. They are ineligible for an ETA. To return to the UK, they must now present either a British passport or a costly Certificate of Entitlement attached to their foreign passport. Many who have lived abroad for years, or who never needed a UK passport to travel home before, are now scrambling to obtain these documents, a process that takes weeks and costs between £100 and £589.

The £10 ETA itself is straightforward for eligible travelers. Applied for via a government app, it grants multiple visits over two years for tourism or business. Approval often comes in minutes. But for dual citizens, the transition has been jarring. Despite government communications campaigns since 2023, some abroad when the rule was finalized say they lacked sufficient time to adapt.

A Home Office spokesperson maintains that ample public guidance has been provided. Meanwhile, airlines and rail operators have been equipped to check ETA status digitally, and travelers without the proper authorization risk being denied boarding. The UK joins nations like the U.S. and Canada in using such a system, but for its own dual citizens, the path home has suddenly become more complicated and expensive.
