Naturalisation as a British Citizen

What is Naturalisation?

Naturalisation is the legal process by which a person becomes a natural citizen of the UK. You can become a British citizen either by birth or you can apply for naturalisation if you are aged 18 or over. To be eligible to become a British citizen, you need to prove that you have been in the UK on Indefinite Leave to Remain or EU Settled Status for at least three years, and that you have never broken UK law, including immigration breaches.

Once your permanent residence status request is approved, you can live, work and study in the UK permanently, without any immigration restrictions. You will also be able to travel and spend time abroad without the need to worry about losing your status.

What are the eligibility requirements to become a British Citizen?

The eligibility requirements to become a British citizen are set out in the British Nationality Act 1981. You need to meet the following requirements to be eligible to become a British citizen:

  • Be over the age of 18.
  • Have spent at least 5 years of continuous residence in the UK, with no longer than 450 days outside the UK.
  • Have held Indefinite Leave to Remain (ILR) in the UK for at least 12 months.
  • Meet the B1 CEFR level English language requirements (unless exempt).
  • Pass the Life in the UK Test, to show that you are aware of the basics of the British customs, traditions, and culture.
  • Not have been in breach of any UK immigration rules.
  • Demonstrate that they meet the Good Character requirement.

Exemptions for the English Language Naturalisation Requirements

Situations where evidence of proficiency in the British language would not be required for a Naturalisation application, are:

  • Evidence of having completed a degree which was either taught or researched in English.
  • Are either under 18 or aged 65 or over
  • Suffer from a severe physical or mental condition that has affected you on a long term basis.

How can I show I am a person of Good Character?

To qualify for British citizenship, you must demonstrate your “good character”. In deciding whether you are a person of good character, the Home Office will consider your criminal record, if any. British nationality law is quite strict, and thorough background checks are an important part of validating your legal right to claim citizenship in the UK. The Home Office will also review any criminal offence committed overseas and UK immigration-related issue. Generally, the UKVI and the Home Office will not consider applications if a person has held a custodial sentence for four years or longer. Furthermore, those who fail to disclose the full details of their criminal history will also have their application automatically refused. The Home Office will, however, consider any contributions that you may have made to the society since you have been in the UK.

It can be extremely difficult to navigate through the naturalisation process, having a member of our expert London-based team guide you effortlessly through the process will not only put your mind at ease but give you the best chances of success.

What if my Naturalisation Application is refused?

There are numerous reasons why a British Naturalisation application may be refused, some of the most common reasons for refusal are:

  • Naturalisation refused to an existing CCJ
  • Naturalisation refused due to tax reasons
  • Naturalisation refused due to employment history
  • Refusal based on character
  • Refusal as a result of a criminal history

Your Naturalisation may be refused on the basis of a previous conviction, but attention may be given to the type of sentence received (whether it was custodial or non-custodial), the length of time served, and whether the nature of the crime occurred once or reoccurred on multiple occasions.
Unfortunately, in the event of a refused naturalisation, there is currently no grounds for appeal. If however you believe your case is strong enough to have the original decision overturned, it is possible to submit a Request to Reconsider application which costs £372.
Alternatively, you can reapply for Naturalisation on a fresh basis, though you would be required to pay the application fee of £1,330 again.
If you are uncertain of anything, or you have any doubts that your application may be refused, contact one of our London offices, where our specialist Immigration advisors will give you, accurate advice gained from their years of experience.

Is Indefinite Leave to Remain same as British citizenship?

Although ILR (including permanent residence and EU settled status) and British citizenship entitle you to the same rights, these are two distinct statuses under Immigration law.
You can apply for ILR after five years of continuous residence in the UK. Once you are granted ILR, you will be officially a British settled person, and you will be able to live permanently in the UK, access public funds, be joined by your family and leave and re-enter the country without the need to apply for a visa.
Holding ILR is a mandatory step before you can naturalise in the UK as a citizen. However, it is essential to note that you can lose your ILR status if you live outside the UK for more than two years. You must have held ILR for at least 12 months to become eligible to apply for British citizenship. This is the same requirements for those who hold Indefinite Leave to Enter, and to EU and EEA citizens who have held EU settled status for a specific amount of time. During the 12-month qualifying period, you cannot spend more than 90 days away from the UK. You may be asked to provide details about any absence that you had made before submitted your request.
On the contrary, British citizenship will grant you full rights and responsibilities, including the ability to vote in parliamentary and local elections and to obtain a British passport. Most importantly, you will be able to leave the UK for unlimited periods of time without worrying about losing your status.
