If your child is born in the UK, you might wonder if they can hold dual citizenship. Children born in the UK can have dual citizenship if one or both parents are British citizens or have settled status at the time of their birth. This means your child can be a British citizen and also hold citizenship from another country, depending on your family’s situation.
Understanding the rules around dual citizenship is important to help you plan for your child's future. The qualifications depend on parental nationality and the child’s birth circumstances, so knowing what applies to you will make the process clearer.
This guide covers key things you need to know to secure your child’s citizenship rights in the UK while keeping any other nationality. You’ll learn about eligibility, legal steps, and how your family’s status affects your child’s citizenship options. For more details, you can visit information on children born in the UK to non-British parents.
Understanding UK Dual Citizenship for Children
When your child holds dual citizenship, they legally belong to two countries at the same time. This status comes with specific rules under British nationality law, affecting how your child can live, work, and travel. You need to know what dual citizenship means, how UK law applies to children, and what rights and responsibilities your child will have.
Definition of Dual Citizenship
Dual citizenship means your child is recognised as a citizen by two different countries simultaneously. This can happen if your child is born in the UK and you hold a foreign nationality, or if your child is born abroad to British parents.
Holding dual citizenship allows your child to benefit from the rights of both countries, such as access to education, healthcare, and work. However, it may also mean they have to follow the laws and obligations of both nations, like paying taxes or serving in the military.
Dual citizenship is legal in the UK, and your child does not usually have to give up their other nationality when they become British. You should check the laws of the other country because some nations do not allow dual nationality.
British Nationality Law and Children
British nationality law sets out who is entitled to UK citizenship from birth or later. If your child is born in the UK, they can become a British citizen automatically if at least one parent is a British citizen or has settled status.
If neither parent meets these conditions, your child might not be British at birth but could apply for citizenship later. It’s important to understand these rules to ensure your child’s status is secure and recognised.
The law also acknowledges that you can pass citizenship through descent. For example, if you are British but your child is born abroad, your child might still qualify. The application process requires careful documentation, which varies based on your family’s situation.
Citizenship Rights and Responsibilities
With UK citizenship, your child gains important rights. These include the right to live, work, and study in the UK without restrictions. They can also access public services, vote in elections once they reach 18, and apply for a British passport.
At the same time, citizenship carries responsibilities. Your child must respect UK laws and may be liable for taxes or other legal duties. If they hold another nationality, they must also be aware of responsibilities in that country.
Understanding both sets of rights and responsibilities helps you prepare your child for life as a dual citizen. Being aware of these can avoid legal issues and ensure your child benefits fully from their citizenship. For more on British nationality law for children and the rights and responsibilities tied to dual citizenship see this detailed guide.
Eligibility Criteria for Children
Your child's eligibility for British citizenship depends on where they were born, your immigration status, and the specific legal rules under the British Nationality Act 1981. Different rules apply if your child is born in the UK or abroad, and whether citizenship is automatic or requires application.
Children Born in the UK
If your child is born in the UK, they automatically become a British citizen at birth only if at least one parent is a British citizen or has settled status. Settled status means having indefinite leave to remain (ILR) or permanent residence.
If your child’s parents do not have settled status or are not British citizens, the child will not automatically gain citizenship. However, the child may register as a British citizen later if they live in the UK for the first 10 years of their life.
This rule comes from the British Nationality Act 1981, particularly section 1(3). Automatic citizenship for children born in the UK depends heavily on parental status at the time of birth.
Children Born Outside the UK
Children born outside the UK usually do not receive automatic British citizenship unless at least one parent is a British citizen otherwise than by descent. This means the parent must have been born in the UK, naturalised, or registered as a citizen.
If the parent is a British citizen by descent, your child may need to apply for registration to become a British citizen. Their eligibility depends on your residency status, the child’s age, and the circumstances of your family.
Children born outside the UK may also qualify for British citizenship if their parents later return and settle in the UK. The rules aim to maintain a clear connection to the UK but allow flexibility through registration options.
Parental Status and Immigration Status
Your own immigration status strongly affects your child’s citizenship status. If you have settled status or ILR, your child born in the UK is usually entitled to citizenship at birth.
If you do not have settled status at your child’s birth, they may not be automatically British but could later apply to register based on residency. This is a discretionary process, not an automatic right.
Being a British citizen yourself gives your child the right to British nationality, but different rules apply if you are a British Overseas Territories citizen or have limited leave to remain. These variations can influence the type of citizenship your child qualifies for.
Entitlement vs. Discretionary Registration
Some children have entitlement to British citizenship, meaning they automatically qualify or can register as a right. For example, children born in the UK to parents with settled status have this entitlement.
Other children fall under discretionary registration, where the Home Office decides on a case-by-case basis. Factors include the child’s residency, connections to the UK, and the parent's immigration status.
Discretionary registration can apply to children born in the UK when parents do not have settled status or if the child was born abroad to British citizens by descent.
Understanding whether your child qualifies under entitlement or discretionary rules helps you plan the correct application process for British citizenship. For detailed advice on this, see guidance on getting British citizenship for children.
How to Apply for UK Dual Citizenship for Children
Applying for UK dual citizenship for your child involves providing specific documents, following a clear process, and understanding the right forms and fees. You need to carefully prepare and submit your child’s application to ensure it meets the requirements for registration as a British citizen.
Required Documents and Evidence
You must gather all necessary documents before starting the application. This includes your child’s birth certificate, which shows their place of birth and parentage.
If applicable, include your marriage certificate or evidence of a parent’s settled status in the UK. You also need proof that one parent is British or applying for citizenship.
Supporting documents may also include passports, immigration status papers, and any travel documents your child holds. Ensure all documents are originals or certified copies.
The UK government website lists all required documents, so check it carefully to avoid delays.
Step-by-Step Registration Process
First, confirm your child’s eligibility for registration by checking their parent’s citizenship or settled status.
Next, complete the correct application form and collect all required documents. Submit the application by post along with the fee.
You will need to provide biometric information such as fingerprints and a photo. This can be done at a local UKVCAS centre.
Once submitted, the application will be reviewed, which can take several months. If successful, your child will be registered as a British citizen.
After registration, you can apply for a UK passport for your child to use as official travel identification.
Form MN1 and Section 3(1) Applications
Form MN1 is the main application form for registering children under 18 as British citizens. It covers most cases where the child has a British parent or one who is settled in the UK.
Alternatively, Section 3(1) applications apply in certain cases, such as where a parent is applying to become British. This section allows you to register your child based on your own application.
You must fill in the correct form accurately and provide all supporting evidence related to your situation. Errors or missing documents can cause delays or refusals.
Check the latest version of Form MN1 and guidance for Section 3(1) on the UK government website before you apply.
Application Fees and Processing Times
The current application fee must be paid when you submit the registration form. Fees are non-refundable even if the application is refused.
For children under 18, the fee covers the registration process only. If your child turns 18 during the process, they may need to pay an additional citizenship ceremony fee.
Processing times vary, but expect around 3 to 6 months. Complex cases may take longer.
You can track your application status online via the UK government website and should receive updates by email or post.
Prepare for all costs, including any fees for obtaining biometric appointments and the child’s UK passport application.

British Citizenship by Birth, Descent, and Naturalisation
You can acquire British citizenship in different ways depending on where you were born and your parents’ status. Some citizenships are automatic, while others require an application through naturalisation. Your child’s eligibility will depend on specific rules about birth, descent, and residence.
Automatic Citizenship and Citizenship by Birth
If your child was born in the UK on or after 1 January 1983, they usually become a British citizen automatically if at least one parent is a British citizen or has settled status. “Settled” means the parent has indefinite leave to remain or permanent residency. If neither parent is settled or British, your child will not automatically be British, but they may apply to register later.
Children born in the UK who were initially not British can register to become citizens once their parents gain settled status.
Citizenship by Descent
If your child was born outside the UK, they might still be British by descent if at least one parent is a British citizen otherwise than by descent. This means that the parent was born in the UK, naturalised, or registered before the child’s birth.
British citizenship by descent can be passed down only one generation born abroad. So, your child might be British, but they cannot automatically pass that citizenship to their children if those children are also born overseas.
Naturalisation and Residency Requirements
You can apply to naturalise as a British citizen if you meet residency and other conditions. For your child, this usually means they have lived in the UK for a set period and have indefinite leave to remain or settled status, often under the EU Settlement Scheme.
Applicants must also meet the “good character” requirement, showing no serious criminal record or immigration fraud. Children under 18 may have different rules, but naturalisation generally involves:
Living in the UK for at least 3 years before applying
Holding indefinite leave to remain or settled status
Passing the Life in the UK test (usually adults only)
Naturalisation gives your child full citizenship rights regardless of birth location. For more detail on how your child can register or naturalise, see Getting British citizenship for children.
Legal and Practical Considerations for Parents
When managing dual citizenship for your child, you need to understand the Home Office’s role, seek proper legal advice, and consider how foreign citizenship may affect your child’s status. These areas shape how you should plan applications and future care for your child's nationality.
Home Office Decisions and Legal Guidance
The Home Office decides if your child can have British citizenship alongside another nationality. They assess factors like your child’s birth in the UK, your own immigration status, and whether you meet residency requirements.
You must apply correctly and provide all required documents to avoid delays or refusals. After approval, your child will usually attend a citizenship ceremony, which confirms their British status.
The Home Office also offers guidance about the rights and responsibilities linked to citizenship. Keeping updated with their rules is important, as immigration laws change over time.
Professional Legal Advice and Support
You should consider obtaining professional legal advice when pursuing dual citizenship for your child. A solicitor with expertise in immigration law can help you understand complex rules and fill out forms accurately.
This support reduces errors that might affect your child’s status or delay the process. Legal advisers can also clarify how your child’s citizenship affects future travel, education, and work rights.
If your case involves unusual circumstances, such as complicated parental immigration histories, legal guidance is essential to navigate the system properly.
Dual Citizenship and Foreign Citizenship Issues
Your child can hold dual citizenship, but some countries restrict this or require certain actions, like reporting another nationality. You need to check the rules of your child’s foreign citizenship, as these may affect their rights or obligations abroad.
Bearing dual nationality may mean different legal duties in each country, such as tax or military service, depending on those laws. You should explain these matters to your child as they mature.
You must also be aware that holding a foreign citizenship does not give automatic protection under UK law if abroad. Knowing these facts helps you plan for your child’s future safely.
For more detailed legal insight, you can refer to legal guidance from immigration experts.
Frequently Asked Questions
You need to know how citizenship rules apply depending on where your child is born and your status in the UK. The rights to a British passport and dual citizenship depend on factors like your residency and your child’s birthplace.
What are the eligibility requirements for a child born abroad to obtain British citizenship?
Your child can automatically get British citizenship if at least one parent is a British citizen "otherwise than by descent." If your child is born abroad and only one parent is British by descent, you might need to register them as a British citizen.
Is a child born in the UK to non-British parents entitled to citizenship?
A child born in the UK does not automatically get British citizenship unless at least one parent has settled status or is a British citizen. If neither parent has settled status or citizenship, your child will not have British citizenship at birth.
How does having settled status affect my child's right to a British passport?
If you hold settled status in the UK, your child born in the UK can usually get British citizenship automatically. This right gives your child the ability to apply for a British passport without extra residency requirements.
Are there any disadvantages to my child holding dual citizenship in the UK?
Dual citizenship can mean your child must follow the laws and obligations of both countries. This might include paying taxes or military service in some countries. You should also check how other countries view dual citizenship as rules vary.
What is the process for applying for a British passport for a child born overseas?
You must provide proof of your child’s British citizenship, including birth certificates and parental citizenship documents. The application is made through the UK passport office and requires completing the correct forms and paying fees.
Does a child born in the UK automatically receive citizenship after living here for 5 years?
No, simply living in the UK for five years does not grant automatic citizenship. Your child must either have a parent with settled status or apply for citizenship once they meet specific residency and legal criteria.
