What is Naturalisation?

Naturalization is the legal way for someone to become a British citizen in the UK. You can become a British citizen by being born in the UK or applying for naturalization if you’re 18+. To be eligible, you usually need to have had Indefinite Leave to Remain (ILR) or EU Settled Status for at least three years and show that you are a good person by following UK immigration laws and not having any serious criminal convictions.

Once your application for British citizenship is approved, you can live, work, and study in the UK without any immigration restrictions. You can also come and go from the UK without worrying about your status. Adam Bernard Solicitors, expert British citizenship and naturalisation solicitors in London, provide trusted legal advice to clients across London, the UK, and worldwide, ensuring applications meet Home Office nationality requirements and are submitted correctly.

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

You must show that you meet the “good character” requirement under UK nationality law in order to become a British citizen. The Home Office and UK Visas and Immigration (UKVI) will look closely at your criminal record, both in the UK and abroad, as well as your immigration history, including any times you broke UK immigration rules.

British nationality law is still strict, and every application for naturalization must include more thorough background checks. According to current Home Office policy, applications are usually denied if the applicant has been sentenced to four years or more in prison. If the applicant refuses to disclose or conceals their criminal history, their application may be automatically denied. The Home Office will also look at civil penalties, fines, and patterns of not following the rules.

But decision-makers may think about how long someone has lived in the UK, worked there, been involved in the community, or gone through rehabilitation as positive contributions to society. Adam Bernard Solicitors are expert British citizenship and naturalization lawyers in London. They give specialized advice to clients all over London, the UK, and the world, helping applicants show strong good-character evidence that follows the most recent Home Office nationality guidance.

How long does the British Naturalisation application process take?

Once your application is approved, you will need to wait until you are summoned for your Citizenship ceremony to receive your Naturalisation certificate and thereafter apply for your British Passport.

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.
