Obtaining British Citizenship and Staying Permanently

British nationality law has been subject to significant developments in recent years. We can use our longstanding experience and knowledge to assess your eligibility and assist you with applying for British citizenship.

Whether you are looking to naturalise as a British citizen having obtained indefinite leave to remain, or you are looking to register as a British citizen on the basis of your parents’ nationality or status in the UK, we can provide you with detailed advice and guidance.

We also have experience of handling complex nationality cases which require an understanding of the historic evolution of Britain’s nationality law.

Generally speaking you will be required to have spent six years in the UK to become eligible to apply for naturalisation, however, there are exceptions.

There are strict continuous residence, English language and character requirements to meet in order to qualify and our experienced immigration team will be able to guide you every step of the way to ensure a successful outcome for your application.
