UK Child Visa Extension
Before extending a child’s permission, establish which route the child holds and how it relates to the parents’ status. Family visas and work-route dependant visas have different requirements.

Identify the route before gathering evidence
A child joining or remaining with a parent under the family route is not in the same position as a dependant of a sponsored worker. Read the existing grant and the relevant route guidance together. A parent’s new permission does not automatically extend a child’s permission.
An application may be for further leave, a first grant or another available route. Birth in the UK does not, by itself, establish that an extension is the correct application. Check nationality and any existing permission first.
Family-route children
Under the family route, the child’s age, independence and parental circumstances matter. Qualifying children over 18 may continue where their permission began while they were under 18 and the applicable conditions remain satisfied. Living away for education is not necessarily the same as leading an independent life.
Check the position of both parents. Depending on the circumstances, sole parental responsibility or serious and compelling reasons with suitable care arrangements may need consideration. A birth certificate establishes a relationship but will not necessarily answer every question about responsibility or care.
Work-route dependants
For a Skilled Worker’s child, check the parent’s permission, occupation and relevant sponsorship dates: restrictions can affect whether dependants are eligible. Do not assume that all sponsored workers can bring or extend every dependant.
The child normally needs a separate application, which can be made alongside the parent’s application or before the child’s own permission expires. The applicable rules address age, dependency and parental circumstances. Use the work-route guidance rather than applying the family-route financial requirement automatically.
Build evidence around the child’s circumstances
Prepare identity documents, evidence of the parent-child relationship, immigration decisions and records of the child’s living arrangements. Where relevant, gather education records, financial support evidence and documents explaining parental responsibility or care.
Check which documents the selected route actually requires. Explain changes since the previous grant, including a parent’s status, the child’s age or living arrangements. Do not describe every child as financially independent merely because they are away at school or university.
Plan the application and travel together
Check the child’s expiry date independently of the parents’ dates. Follow the relevant identity-verification instructions; the process is not identical for every applicant. Processing information also varies by route, so an eight-week estimate must not be treated as a universal promise.
For a UK-born child of a Skilled Worker, guidance addresses permission needed to travel out of and return to the UK. Before travelling while an application is pending, check the applicable withdrawal rules. Obtain advice if nationality, existing permission or route eligibility is uncertain.
