UK Tightens Entry Rules for Dual Citizens

The United Kingdom is tightening entry rules for dual citizens, particularly affecting those holding Australian citizenship alongside British or Irish citizenship. Starting February 25, 2026, individuals with dual Australian-British or Australian-Irish citizenship must enter the UK using their UK or Irish passport, dropping the allowance to use their Australian passport.

Significance of the New Rule

This policy change relates to the UK’s Electronic Travel Authorization (ETA) system. This system, which came into effect on January 8, 2025, requires all non-UK and non-Irish passport holders to obtain an ETA prior to entry. The new regulations clarify that British and Irish passport holders are exempt from the ETA requirement, thus must enter the UK using their respective passports.

Impact on Australian Residents

• Nearly one million residents in Australia were born in the UK, translating to a substantial number of potential dual nationals.
• Approximately two million Australians are eligible for UK passports, combining those born in the UK and those who qualify by parentage.
• During the year ending June 30, 2025, over one million Australians visited the UK for short trips, many likely being dual nationals.

Expiration of Passports

After the new rules take effect, dual citizens with expired UK or Irish passports may face entry challenges. While the UK cannot deny entry to its own citizens or Irish nationals, a current passport is necessary for boarding a flight. Using an expired passport may result in complications at check-in.

Renewal Process

The renewal process for UK and Irish passports is straightforward:

• UK passports: Online renewal costs £94.50 ($190) for adults and £61.50 ($124) for children.
• Irish passports: Renewals can be completed online through the Department of Foreign Affairs, at a cost of €75 ($131) for a standard 10-year passport.

Eligibility for UK Citizenship

Australians who have never applied for a UK passport may still be citizens if born in the UK or if British parents were their parents. To determine citizenship, factors such as the birthplace and date of birth play a crucial role.

Considering Dual Nationality

For some Australians, holding a UK passport might not be desirable, particularly after Brexit. Those considering renouncing their UK citizenship can refer to the UK government’s citizenship website for more information on the process.

The ETA System and Border Control Innovations

The implementation of electronic passport scanning across the UK aims to enhance efficiency in tracking entries and speeding up border control processes. This advancement in technology allows for shorter wait times and streamlined entry procedures for travelers.

In summary, the upcoming changes in the United Kingdom’s entry rules for dual citizens underline the importance of being aware of passport requirements. With the tightening of regulations, dual Australians now need to ensure they have the correct documentation before traveling to the UK.
