Naturalisation As A Spouse Of A British Citizen

You can apply to naturalise as a British citizen if you are married to a British Citizen and you have Indefinite Leave to Remain (ILR) in the UK. An application for naturalisation as a spouse of a British Citizen is made using application form AN.

Eligibility Requirements For Naturalisation As A Spouse Of A British Citizen

If you’re married to, or the civil partner of, a British citizen, you can apply for naturalisation as British Citizen under section 6(2) of the British Nationality Act 1981 if:

  • you’re 18 or over
  • you’re of sound mind, you’re able to think and make decisions for yourself
  • you’re of good character, for example you don’t have a serious or recent criminal record
  • you’ve met the knowledge of English and life in the UK requirements
  • you’ve been granted indefinite leave to stay in the UK (this means there’s no specific date that you have to leave) or permanent residence if you’re an EEA national (and you have a permanent residence card or document that shows you have permanent residence)
  • you meet the residency requirement

Unless your spouse or civil partner works abroad either for the UK government or for an organisation closely linked to government, you must usually also have:

  • lived in the UK for at least the 3 years before your application is received
  • spent no more than 270 days outside the UK in those 3 years
  • spent no more than 90 days outside the UK in the last 12 months
  • not broken any immigration laws while in the UK

When applying under section 6(2) of the British Nationality Act 1981, the applicant is not required to wait 12 months after the grant of ILR before applying for British Citizenship. An application for British Citizenship can be made soon after the grant of ILR if your spouse is British Citizen.

Good Character Requirement For Naturalisation As A British Citizen

An applicant for naturalisation as a British Citizen must satisfy the good character requirement to succeed in his application. The British Nationality Act 1981 does not define good character. However, the Home Office UKVI guidance sets out the types of conduct which must be taken into account when assessing whether a person has satisfied the requirement to be of good character. Consideration should be given by the Home Office caseworker to all aspects of a person’s character, including both negative factors, for example criminality, immigration law breaches and deception, and positive facto

Two Referees For Naturalisation As A British Citizen

The naturalisation application Form (AN) requires an applicant to be supported by two referees. One referee must be a person of professional standing and the other must be the holder of a British citizen passport and either a professional person or over the age of 25.

Tariq has been the most amazing help over the past several months. He guided my husband and I through our Fiance visa and Partner FLR M visa. Both times Tariq made sure we provided ample evidence, submitted everything in a timely manner, and communicated any potential issues. We are so grateful for everything and highly recommend this practice to anyone needing similar services!

I don’t usually leave reviews like this at all, but I couldn’t not leave one for sunrise solicitors and particularly Mr Rizwy for all the time, effort and patience they had working on my case and providing me with the service that they did. I am very particular about details, especially with something this important, and my case involved a huge amount of evidence, documents and information that needed to be properly understood rather than just read through because it was extremely personal and the case is about more than just paperwork. I asked a lot of questions and raised things to him repeatedly when I was worried about them, and sent a massive amount of material for him to deal with. At no point did I feel like I was being rushed, ignored or treated as difficult. If I raised something, he listened to it. If something needed checking, he checked it. And when I needed something explained, he explained it properly rather than giving me a vague answer and moving on. That’s probably what I appreciated the most working with sunrise solicitors. I am extremely grateful to Mr Rizwy and everyone at Sunrise Solicitors for the amount of work they put into my case and for the patience they showed me throughout. I have been dealing with this matter for a long time, so having a solicitor I could actually trust with it meant a great deal to me. I have nothing but positive things to say about the way they handled my case.
