Obtaining British citizenship

The Process of Applying for British Citizenship

Applying for British citizenship is a significant step that allows individuals to enjoy the full benefits and responsibilities of being a British citizen. The process involves several steps, including meeting eligibility criteria, gathering necessary documentation, and attending a citizenship ceremony. This article outlines the detailed process of applying for British citizenship.

Eligibility Criteria

Before starting the application process, it’s important to ensure that you meet the eligibility criteria for British citizenship. The main pathways include naturalization and registration.


For most applicants, the naturalization process is the common route. Eligibility criteria include:

  • Age: You must be 18 years or older.
  • Residency: You must have lived in the UK for at least 5 years before applying. If you are married to or in a civil partnership with a British citizen, the required residency period is 3 years.
  • Indefinite Leave to Remain: You must have indefinite leave to remain (ILR) or settled status under the EU Settlement Scheme for at least 12 months (unless you are married to a British citizen).
  • Absences: You must not have spent more than 450 days outside the UK during the 5-year residency period (or 270 days during the 3-year period for spouses of British citizens).
  • Good Character: You must be of good character, with no serious or recent criminal record, and no breaches of immigration laws.


Certain individuals, such as children or those with specific circumstances, may be eligible for registration as British citizens. Criteria vary based on individual cases, such as children born in the UK to non-British parents who later acquire settled status.

Preparing Your Application

Gather Required Documents

Collect the necessary documentation to support your application. Common documents include:

  • Proof of Identity: A valid passport or travel document.
  • Residency Evidence: Documents such as utility bills, bank statements, or letters from employers to prove your residency.
  • Proof of ILR or Settled Status: Documentation showing your immigration status.
  • Language Proficiency: Evidence of passing an approved English language test or holding an academic qualification taught in English.
  • Life in the UK Test: A pass certificate from the Life in the UK test.

Complete the Application Form

Fill out the appropriate application form. For naturalization, this is form AN. Ensure all sections are completed accurately and honestly. The form requires detailed personal information, including your immigration history, employment details, and residency information.

Pay the Fees

Submit the application fee, which varies depending on the application type. The fee covers processing costs and is non-refundable, even if your application is unsuccessful.

Submitting Your Application

Submit your completed application form along with the required documents and fee. Applications can be submitted online through the UK government website or by post.

Biometric Information

After submitting your application, you will be required to provide biometric information, including fingerprints and a photograph. You will receive instructions on how to do this, usually at a designated application center.

Attending an Interview

In some cases, you may be asked to attend an interview. This is to verify the information provided in your application and assess your knowledge of life in the UK. Prepare for the interview by reviewing your application and understanding key aspects of British culture, history, and values.

Decision on Your Application

The Home Office will review your application and make a decision. This process can take several months. You will be notified in writing of the outcome. If successful, you will receive an invitation to attend a citizenship ceremony.

Citizenship Ceremony

Attending a citizenship ceremony is the final step in becoming a British citizen. Ceremonies are usually conducted by local councils and are a formal requirement. During the ceremony, you will take an oath of allegiance to the Crown and a pledge to respect the UK’s rights and freedoms.

Receiving Your Certificate of Naturalization

After the ceremony, you will receive your Certificate of Naturalization. This document is proof of your British citizenship and allows you to apply for a British passport.

The process of applying for British citizenship involves several steps, from meeting eligibility criteria to attending a citizenship ceremony. Understanding and preparing for each stage ensures a smoother application process. Achieving British citizenship grants numerous benefits and signifies a commitment to the values and responsibilities of being a part of the UK.
