Introduction: why this topic matters
Being born in the UK does not automatically guarantee British citizenship. For families where parents are non-British, understanding the legal framework surrounding a child’s nationality, residence rights, and future options is essential.
Knowing when a child qualifies for citizenship, when registration is needed, and how to secure long-term rights can prevent serious complications down the line. This guide explains automatic citizenship, registration pathways, residence rights, and practical steps for non-British parents.
Automatic citizenship at birth, when does a child born in the UK become British
A child born in the UK only becomes automatically British if at least one parent has settled status or British citizenship at the time of birth. Being born on UK soil alone is not sufficient.
Key points:
-
The parent must have settled status or British citizenship at the child’s birth.
-
Automatic citizenship is different from that by descent, allowing future children born abroad to inherit citizenship (in most cases).
What “settled status” or “indefinite leave to remain” means
“Settled status” generally refers to indefinite leave to remain (ILR), permanent residence, or other legally recognised settlement statuses.
-
If a parent holds this status at the child’s birth, the child automatically acquires British citizenship.
-
Eligible children can apply for a British passport without additional registration.
Marriage and parental status, does it affect citizenship at birth
Whether parents are married or not usually does not affect the child’s entitlement to citizenship, provided the parent has a settled status or citizenship.
Important nuances:
-
If only the father is settled or British and the parents are unmarried, additional proof of paternity or parental responsibility may be required.
-
Legal parentage matters in complex cases, particularly for registration or discretionary applications.
What happens if neither parent is British nor settled at the time of birth
If neither parent is a British citizen or has settled status when the child is born, the child does not automatically become British.
-
The child’s rights depend on immigration status.
-
Future registration may be required, including:
-
Section 1(3) – if a parent later gains settled status or citizenship
-
Section 1(4) – 10-year residence route
-
Section 3(1) – discretionary registration
-
Children may remain in the UK as dependents of their parents’ visa until citizenship or settled status is obtained.
Registering the child later, pathways to British citizenship
Registration under section 1(3) of the British Nationality Act
If a parent gains settled status or British citizenship after the child’s birth and the child is still under 18, the child can be registered under section 1(3).
Benefits and requirements:
-
Grants full British citizenship otherwise than by descent.
-
Child can pass citizenship to future children born abroad.
-
Requires parental consent from all with legal responsibility.
-
Documentation: birth certificate, proof of parent’s status.
Registration under section 1(4) – 10-year residence route
This route is for children born in the UK who have lived in the country for their first 10 years, with limited absences.
-
Available even if parents were never settled or British.
-
Suitable for long-term residents whose children do not qualify under section 1(3).
Discretionary registration under section 3(1)
For children not eligible under automatic or standard registration, discretionary registration may be possible.
Key considerations:
-
Lawful residence in the UK
-
Parental responsibility and consent
-
Child’s age and good character (if 10 or over)
Approval is at the discretion of authorities and is not guaranteed.
Registration under section 1(3A) – children of armed forces personnel
-
For children born in the UK to parents who join the UK armed forces after birth.
-
Grants British citizenship otherwise than by descent.
-
Ensures children of service members have full rights like other UK-born children.
Requirements (residence, parental status, good character)
Applications require:
-
Child’s full birth certificate
-
Proof of parental settled status or British citizenship
-
Evidence of residence in the UK, where applicable
-
Parental consent from everyone with legal responsibility
-
Children aged 10 or over may be assessed for good character
Complete documentation is essential; missing evidence can lead to refusal.
Long-term residence and rights without citizenship – visa status for the child
If citizenship is not granted immediately:
-
Child’s ability to remain depends on parents’ immigration status.
-
May need a dependent visa or leave to remain.
-
Rights to study, work, and access public services like the NHS can be limited until citizenship or settled status is secured.
Implications for travel, passport, NHS and other public services
-
Children without citizenship or settled status must travel using a valid passport from their non-British nationality.
-
May require a visa to re-enter the UK.
-
Access to public services, including the NHS, schooling, and welfare, may depend on immigration leave.
-
Securing citizenship provides full rights and freedom of movement.
Effect of parents’ later change of status on the child’s rights
-
If parents later obtain settled status or British citizenship, the child may be eligible for registration under section 1(3).
-
Registration must occur before the child turns 18.
-
Once registered, the child gains full rights, including the ability to hold a British passport.
-
Citizenship is usually granted otherwise than by descent, allowing future children born abroad to inherit citizenship automatically.

-
Assuming UK birth = automatic citizenship
-
Missing registration deadlines
-
Lack of documentation, such as birth certificates or proof of parental status
