What is British Citizenship?

UK nationality or British citizenship allows you to live and work in the UK permanently, without any immigration restrictions. Holding British citizenship is also required before applying for a UK passport.

As a British citizen, you can vote in UK elections, apply for a UK passport, enjoy protection from deportation, and access public services such as healthcare.

Many applicants obtain citizenship through naturalisation, but there are also other routes depending on your personal circumstances, such as birth, descent, or registration.

Types of British Citizenship Applications Handled by Our Solicitors

Our British citizenship solicitors in London assist clients with a variety of citizenship applications, depending on individual circumstances:

1. Naturalisation Applications

This is the most common pathway for adults who have held Indefinite Leave to Remain (ILR) or Settled Status for at least 12 months. Applicants must also meet the residency, life in the UK test, good character, and language requirements.

2. Citizenship Through Marriage or Civil Partnership

Spouses or civil partners of British citizens can apply for citizenship after three years of residence in the UK, provided they hold ILR or Settled Status.

3. Citizenship by Birth or Descent

Children born in the UK to settled or British parents are usually eligible for British citizenship by birth, while some children born abroad may qualify through citizenship by descent.

4. Registration as a British Citizen

Certain groups, such as children or individuals with historical connections to the UK, may be able to register as British citizens instead of applying through naturalisation.
