TL;DR
A child under 18 can join a British or settled parent (or one being granted a partner-route visa) in the UK. Where only one parent is here, that parent usually needs sole responsibility for the child, or there must be serious reasons making exclusion undesirable. A non-British child adds £3,800 (first) / £2,400 (each additional) to the £29,000 requirement. Check first whether your child is already British — many are, and need only a passport.
Who qualifies
A child can be granted leave as a dependant if all of these apply:
- The child is under 18 at the date of application (or was last granted leave as a child)
- The child is unmarried, not in a civil partnership, and not leading an independent life
- At least one parent is British or settled, or is being granted leave on the partner route
- One of these parental situations is met (see below)
- The child can be adequately maintained and accommodated without recourse to public funds
The parental requirement
This is the part that decides most child applications:
| Situation | What's needed |
|---|---|
| Both parents settled/British or applying together | Straightforward — both bring the child |
| One parent in the UK | That parent generally needs sole responsibility for the child |
| Other parent shares responsibility | Usually their consent, or "serious and compelling" reasons |
Sole responsibility means you make the important decisions about the child's upbringing — their care, education, health and welfare — even if day-to-day care is delegated to a relative abroad. It's evidenced over time: school and medical decisions, financial support, regular contact, and arrangements you direct.
Where the child has lived with another parent or relative who shares real responsibility, the application instead has to show serious and compelling family or other considerations that make excluding the child undesirable.
Is your child already British?
Check this before applying for any visa — it's the most common avoidable mistake:
- A child born in the UK to a parent who was British or settled at the time of birth is usually British automatically — apply for a passport, not a visa.
- A child born outside the UK to a British citizen parent may be British by descent.
If the child is British, they don't need a visa at all.
The financial requirement
For the partner/parent route, the sponsor must meet the £29,000 financial requirement. A non-British dependent child increases it:
- +£3,800 for the first child
- +£2,400 for each additional child
A child who is British or already settled in the UK does not increase the requirement.
Evidencing sole responsibility
Where only one parent is in the UK, "sole responsibility" is usually the crux — and it's evidenced over time, not asserted. Caseworkers look for proof that you make the continuing, important decisions about the child's life:
- Financial support — regular remittances, school fees, medical costs you pay
- Decision-making — you choosing the child's school, consenting to medical treatment, directing their care
- Contact — sustained communication: calls, messages, visits
- Care arrangements you direct — even where a relative provides day-to-day care abroad, the decisions are yours
What undermines a sole-responsibility claim is evidence the other parent remains actively involved in those decisions. If they are, the application usually has to rest on "serious and compelling family or other considerations" instead — for example, the carer abroad can no longer cope, or the child's welfare would be at serious risk if they stayed. These are demanding tests that turn on detailed, specific evidence.
Children aged 16 and 17
Older children face extra scrutiny around whether they are leading an independent life. A 17-year-old who is married, living alone, financially independent, or working full-time may not qualify as a dependent child. Caseworkers also weigh how integrated the child already is into life in their home country. Evidence that the child remains part of the family unit — living with a parent or family, financially dependent, in education — helps.
A child who turns 18 partway through the process is generally assessed on their age at the date of application, so apply in good time before an 18th birthday if the child route is the basis.
Could your child register as British instead?
In some cases a child doesn't need a visa at all — they can register as a British citizen, which is often the better long-term outcome because it's permanent and avoids future visa fees. Common routes include a child born in the UK who lives here until age 10, or a child one of whose parents becomes British or settled while the child is under 18. Registration has its own fee and criteria, but where it's available it usually beats a time-limited visa. Check a child's citizenship and registration options before defaulting to a visa application.
Documents
- The child's passport
- The child's birth certificate naming both parents
- The sponsoring parent's proof of British/settled status (passport, BRP, eVisa share code, naturalisation certificate)
- Evidence of the relationship and responsibility — who cares for, supports and decides for the child
- Consent from any non-applying parent with shared responsibility (and evidence of sole responsibility where that's the basis)
- Evidence the financial and accommodation requirements are met
- A TB test certificate if applying from a listed country
- Certified translations of any non-English document
Sole-responsibility and shared-care cases turn on fine detail and are a frequent refusal point — worth a professional review where the parental situation is anything but straightforward.

Common questions
- 01
Who can bring a child to the UK on a family visa?
A child under 18 can join a parent who is British or settled in the UK, or who is being granted/holds a partner-route visa. Either both parents must be settled or applying together, or the parent in the UK must have sole responsibility for the child, or there must be serious reasons making exclusion undesirable.
- 02
What is the 'sole responsibility' test?
Where only one parent is in the UK, that parent generally must show sole responsibility for the child's upbringing — making the key decisions about their care, education and welfare. If the other parent shares responsibility, the application usually needs their consent and may rely on 'serious and compelling' circumstances instead.
- 03
Does a child increase the financial requirement?
A non-British dependent child adds £3,800 for the first child and £2,400 for each additional child on top of the £29,000 partner/parent threshold. Children who are British or already settled in the UK do not increase the requirement.
- 04
Is my child already British?
Possibly. A child born in the UK to a parent who was British or settled at the time of birth is usually British automatically and needs no visa — apply for a passport instead. A child born outside the UK to a British citizen parent may also be British by descent. Check status before applying for a visa.
- 05
What documents does a child visa need?
The child's passport and birth certificate naming both parents, the sponsoring parent's proof of British/settled status, evidence of the relationship and of who holds responsibility, consent from any non-applying parent, evidence the financial and accommodation requirements are met, and a TB test if from a listed country.
