Child Benefit
Eligibility for Child Benefit depends on the parent’s immigration and residence status, rather than the child's nationality or immigration status.
An eligible parent may claim Child Benefit regardless of the child’s immigration status. However, when a child has leave to remain with NRPF, legal advice should be obtained from an immigration adviser before an application for Child Benefit is made to find out whether this may adversely affect the child’s current or future immigration position.
When a sole parent or both parents in a household have leave to remain with NRPF, they will not qualify for Child Benefit and will not be able to claim this for a British child. The parent may only be able to claim Child Benefit if an exception applies, such as due to a reciprocal social security agreement that their country of nationality has with the UK.
