Which EU Countries allow for dual citizenship with the UK? (UPDATED)

The uncertainty that has spawned from the UK’s vote to leave the EU in March 2019 has led to a considerable number of EU nationals applying to recognise their permanent residence rights in the UK. Many are now attempting to solidify these rights by applying to naturalise as a British citizen.

Our previous article covering these issues raised many questions from readers which alluded to the complexities of nationality law in some of these countries. Some countries have complex rules which allow dual citizenship where a person takes on a second nationality by birth, but not where this is by naturalisation. This article sets out clearly the position of these EU countries in relation to dual citizenship with the UK, differentiating between those who allow dual citizenship under all, certain, or no circumstances.

Those that allow dual citizenship with the UK

Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Luxembourg, Malta, Poland, Portugal, Romania, Slovenia, Spain, Sweden.

Those that allow dual citizenship with the UK subject to certain conditions
