Choosing a British citizenship referee means finding someone who knows you and meets the Home Office’s requirements. For an adult naturalisation application, you need two referees, and each must qualify for the role they fill.
A friend, colleague or professional contact may be suitable, but knowing someone well is only part of the check. Their professional standing, nationality, relationship to you and length of acquaintance also matter.
This guide focuses on referees for adult naturalisation applications. Applications to register children as British citizens have additional referee considerations.
You need two referees for an adult naturalisation application:
| Referee | Main requirement |
|---|---|
| One referee | A person with professional standing, of any nationality |
| The other referee | A British citizen passport holder who is either a professional person or over 25 |
Both must have known you for at least three years. Neither can be related to you or to the other referee, represent you in the application, or work for the Home Office.
Finding suitable referees can take longer than expected. A trusted friend might meet the passport and age requirements but not qualify as your professional referee. A professional contact might have known you for too short a time.
Check both people before asking them to complete declarations. This helps you avoid replacing a referee late in your preparations.
If you are applying for British citizenship, treat referee checks as part of your application checklist rather than a last-minute signature task.
Your professional referee can have any nationality. They must have professional standing, as well as meeting the other referee requirements.
The Home Office gives examples such as a minister of religion, a civil servant, or a member of a professional body, including an accountant or solicitor. A solicitor representing you in the citizenship application cannot act as your referee.
Check the person’s actual role and qualifications. A job title that sounds senior does not automatically establish professional standing.
For example, an American accountant who belongs to a professional body could be a candidate for this role. You would still need to check the length of acquaintance and the other restrictions.
Your other referee must hold a British citizen passport. They must also be either a professional person or over 25.
The wording matters: a non-professional person who is exactly 25 does not meet the “over 25” condition. Someone younger may qualify through professional standing, provided they meet the remaining requirements.
You still need two separate people, even if one person could meet the requirements for either role.
Do not choose someone who:
The Home Office also normally excludes someone who has a conviction for an imprisonable offence within the previous ten years. It may check referees’ qualifications, convictions and signatures.
This means that two relatives cannot act together simply because neither is related to you. For example, a married couple would not be a suitable referee pair.
If a potential referee has a relevant conviction or an uncertain professional status, resolve that question before relying on them.
A friend or colleague may qualify. The important question is whether they meet the requirements for their particular role.
Consider these examples:
These examples illustrate how to assess possible referees. They do not establish that a particular person qualifies without checking their circumstances.
Start by listing people you already know through work, professional associations, community activities or friendships. Then check each candidate against the official criteria.
Referees help confirm your identity and endorse the application through the relevant declaration. They should read the declaration carefully and provide accurate information.
Follow the instructions in your application for the photograph, signatures and supporting documents. Do not assume that a general character-reference letter can replace the required declaration.
A referee’s endorsement also does not replace your proof of immigration status or establish that you meet every citizenship requirement.
Someone who sponsored a previous visa does not automatically qualify as your citizenship referee.
For example, a Government Authorised Exchange visa involves sponsorship for a temporary immigration route. Citizenship referees serve a separate purpose and must meet the nationality application requirements.
A former sponsor contact could only act as a referee if that individual independently meets the relevant criteria.
Use a simple sequence to organise this part of the application:
Contact referees early when planning your citizenship application timelines. Holidays, work commitments or uncertainty about eligibility can slow down preparation.
Alongside the declarations, check your other application requirements, including the Life in the UK test, where applicable.
First, widen your search among people who already know you. Consider professional contacts and community connections rather than only close friends.
Do not ask a stranger to sign or give an inaccurate account of how long someone has known you. Explain any difficulty to an immigration adviser before submitting your application.
There is a specific provision for applicants living outside the UK who do not know a suitable British citizen passport holder. Home Office guidance allows a Commonwealth citizen or a citizen of the country of residence in certain circumstances, subject to the other requirements and consular acceptance. Check how this applies before relying on it.
For related guidance, explore:
For an adult naturalisation application, you need two separate referees. Both must meet the requirements for their respective roles.
No. The professional referee can have any nationality. The other referee normally needs a British citizen passport and must be either a professional person or over 25.
No. Referees must not be related to you. They must also not be related to each other.
Each referee must have known you for at least three years. Check this separately for both people.
A solicitor representing you in the citizenship application cannot act as your referee. A different solicitor could qualify if they meet all the relevant requirements.
Choosing a British citizenship referee involves more than finding someone willing to sign. For adult naturalisation, you need two suitable people who meet different requirements and have each known you for at least three years.
Before submitting your application, check their professional standing, passport eligibility and relationships. Follow the declaration instructions carefully and allow time to resolve any uncertainty.
