What is British Naturalisation?

British naturalisation is the legal process used by people with UK settlement status to become British citizens. It is commonly used by applicants who hold ILR, settled status or another qualifying permanent status and meet the Home Office requirements for citizenship.

After naturalisation, applicants receive British citizenship and can access citizenship rights, including applying for a British passport.
 

Benefits of British Naturalisation

British naturalisation gives you British citizenship and removes the immigration restrictions linked to visas and settlement status. As a British citizen, you can apply for a British passport, live and work in the UK without immigration restrictions and access the rights and benefits available to UK citizens.

• British passport: Apply for a British passport and travel internationally as a UK citizen.
• Live and work in the UK: Live, work or run a business in the UK without needing a visa.
• Study in the UK: Study in the UK without requiring a student visa.
• Voting rights: Vote in eligible UK elections and participate in civic activities.
• No visa restrictions: No need to renew visas or maintain ILR status.
• Living abroad: Live outside the UK without the absence restrictions that apply to ILR holders.
• Consular support: Access British consular assistance when travelling or living overseas.
   

Who Can Apply for British Naturalisation?

Applicants aged 18 or over can apply for British naturalisation if they hold Indefinite Leave to Remain (ILR), settled status or another qualifying permanent status in the UK and meet the UK citizenship requirements. Most applicants must have held their settlement status for at least 12 months before applying. Applicants married to a British citizen can usually apply without this additional waiting period.

• ILR holders: Usually apply after holding ILR for at least 12 months and meeting the other naturalisation requirements.
• Settled status holders: Usually apply after holding settled status for at least 12 months and meeting the eligibility requirements.
• Spouses of British citizens: Can apply without waiting 12 months after settlement if they meet the 3-year residence route and other naturalisation requirements.

British Naturalisation Certificate

A British naturalisation certificate is the official document issued after you complete your citizenship ceremony. It confirms that you have become a British citizen and is required when applying for your first British passport. You should keep the certificate safe because it is an important legal document and may be needed as proof of citizenship in the future.
 

• Proof of citizenship: Use the certificate as official evidence that you are a British citizen.
• Passport application: Submit your naturalisation certificate when applying for your first British passport.
• Certificate details: Check that your personal information is correct after receiving the certificate.
• Keep it safe: Store the original certificate securely as it is not a travel document and cannot be replaced easily.
   

British Passport After Naturalisation

After receiving your certificate of naturalisation, you can apply for your first British passport. The certificate confirms your British citizenship and must be provided as part of the passport application. A British passport allows you to travel internationally as a UK citizen and access consular support while abroad.
 

• First passport application: Apply for your first British passport after becoming a citizen.
• Required documents: Provide your certificate of naturalisation, identity documents and required passport information.
• Application process: Complete the passport application online and follow the identity verification requirements.
• Passport use: Use your British passport for international travel and proof of UK citizenship.
   

British Citizenship and Dual Nationality

British naturalisation does not require applicants to give up their existing nationality. The UK allows dual citizenship, but whether you can keep your original nationality depends on the laws of your existing country of citizenship.
 

• UK dual citizenship: The UK allows British citizens to hold another nationality alongside British citizenship.
• Existing nationality rules: Check whether your current country allows dual citizenship.
• Using multiple passports: Follow the passport and travel rules of each country if you hold dual citizenship.
• Citizenship rights: British citizens have the same rights and responsibilities whether or not they hold another nationality.
