Check if you're a British citizen

If you or your parents were born in the UK, you might automatically be a British citizen. If you’re not a British citizen automatically, you may still be able to apply to become a British citizen.

Check if your child is already a British citizen

If your child isn’t already a British citizen, you might be able to apply for citizenship for them. It depends on where they were born and your immigration status. For your child’s application to be successful, they usually need to have at least one British parent.
