Your child may not need a visa at all
This is the route families most often miss. A child born in the UK is not automatically British — but if a parent held settled status at the time of birth, that child was British from birth and simply needs a passport. No application, no fee beyond the passport itself.
If neither parent was settled at the time, the child may still have a right to register later: once a parent settles, or once the child has lived in the UK for the first ten years of their life. Registration is permanent and cannot be taken away, which a visa can.
Why it matters more than it looks
Families routinely apply for and renew dependant visas for a child who already qualifies to register as British. That is years of Home Office fees, and a status that has to keep being renewed, for something that could have been settled once.
What we do
We check your own immigration history at the date of your child's birth, establish which route — if any — your child qualifies under, and tell you honestly if the answer is to wait for a parent to naturalise first.
