Dual citizenship is subject to change and can be complicated in some cases. You should check with your Embassy or Consular Office to find out what the situation is with your country.

At the time of writing, Germany only allows dual with another EU country, so German nationals had to apply before the end of the transition period, which ended at 11pm on December 31st 2020. German nationals must check with the German authorities before applying for British citizenship.

Some countries, such as the Netherlands, only allow dual in certain cases, others have specific requirements in order to preserve your citizenship, such as making sure you renew your passport before it expires.

It is crucially important to check with your own consulate, what the rules are for your specific country, before applying for British citizenship, bearing in mind they are often subject to change.

Britain allows more than two citizenships, but you need to check with the consulates of the other countries.

Why is dual citizenship very important?

British citizens are likely to lose their rights to free movement within the EU/EEA. If you lose your EU citizenship, you may no longer enjoy the right to live, work, study in, or retire to, the 27 countries in the EU.

We very strongly advise against applying for UK citizenship if this will mean you will lose your current citizenship.
