Starting February 25, 2026, British dual citizens will face new rules when entering the U.K. They must use their British or Irish passport, or a foreign passport with a paid Certificate of Entitlement.
Previously, dual citizens could enter using their foreign passport without extra documentation. The change comes as part of the U.K.’s Electronic Travel Authorisation (ETA) system, similar to the U.S. ESTA.
The ETA requires visitors from certain countries—including the U.S., Canada, Australia, New Zealand, Japan, and EU nations—to pay £16 ($22) for a two-year digital travel permit. Dual citizens cannot obtain an ETA using a foreign passport, which is why the new rules apply.
For those with a British or Irish passport, the change is minor. Travelers must ensure their passport is valid and use it when departing their country and entering the U.K.
Problems arise for dual citizens who only have a foreign passport. Without proof of British citizenship, they cannot enter. Those born overseas to British parents may need to register their citizenship and obtain a British passport before traveling.
Dual citizens have three main options: use a British/Irish passport, pay for a Certificate of Entitlement (about $800), or renounce U.K. citizenship and travel with an ETA. Emergency travel documents are available for urgent trips at a smaller cost.
These changes do not affect dual citizenship status. They only change how dual nationals must prove their right to enter the U.K. when traveling.
