Dual Citizenship
What is Dual Citizenship?
Dual citizenship (or dual nationality) is the legal status of holding citizenship in two countries simultaneously, with each citizenship conferring its full — or near-full — set of rights and obligations. For travellers, dual citizenship is primarily valuable for "passport power": a holder of two passports can travel on whichever document provides visa-free or easier access to their destination, combining the strengths of both nationalities.
Not all countries permit dual citizenship — some require citizens acquiring a second nationality to formally renounce their original. Countries that do permit it include the UK, US, Australia, Canada, France, Ireland, and Italy (which offers citizenship to direct descendants of Italian nationals through generations, making it particularly sought-after for its EU mobility). Citizenship by investment programmes in Portugal, Malta, and Caribbean nations have grown significantly as high-net-worth individuals seek additional passport optionality.
Example of Dual Citizenship
James had British and Irish citizenship — the Irish through his grandmother's birthright, obtained specifically after Brexit. As an Irish passport holder (EU citizen), he retained freedom of movement across 27 EU countries: no visa requirements, no 90-day tourist limits, the right to live and work anywhere in the Schengen Area. He used his British passport for UK domestic purposes and his Irish passport for everything else. In 2025, this wasn't a niche strategy; it was a pragmatic response to altered travel realities.
