What the rules mean in practice

The UK permits people to hold more than one nationality, and many British citizens also hold passports from other countries. Holding dual nationality does not automatically cancel a British passport. However, the exact implications can vary depending on the other country’s rules: some states restrict or prohibit dual nationality, require notification of foreign citizenship, or impose obligations such as military service.

Travel and passport use

Dual nationals should be aware of the practical steps when travelling. When entering or leaving a country of which you are a national, that country may require you to use its passport. Carrying both passports can simplify crossings and minimise misunderstandings, but travellers should check entry and exit rules, visa requirements and any COVID-19 or health-related documentation in advance.

Consular protection and legal obligations

Consular assistance from the UK may be limited when you are in another country of which you are also a national. Additionally, tax, legal and civic obligations can arise under the laws of either country. Dual nationals should review responsibilities such as taxation, voting rights and potential compulsory services to avoid unexpected liabilities.

Checking eligibility and renewing documents

People considering or holding dual nationality should confirm passport application and renewal procedures through official channels. The UK government website provides guidance on applying for or renewing a British passport, required documents and fees. It is also prudent to consult the embassy or consulate of the other country of nationality for its specific rules.
