UK updates guidance on registering children as British citizens

UK Visas and Immigration updated its caseworker guidance on registering children as British citizens. The September 2026 update adds guidance covering children whose mother is in a same-sex relationship with a British citizen. The document is aimed at staff deciding registration applications by entitlement and discretion.

UK Visas and Immigration has refreshed its staff guidance on registering a minor as a British citizen, both by entitlement and by discretion. The latest update, dated 22 September 2026, adds guidance on the registration of a child whose mother is in a same-sex relationship with a British citizen.

The document is written for caseworkers deciding these applications. It covers children born in and outside the UK, discretionary applications, children of unmarried British or settled fathers, and parental arrangements.

What this means for travelers

• This is internal decision-making guidance, not a new application route or fee change.
• It may affect how applications involving a mother in a same-sex relationship with a British citizen are assessed.
• Families relying on the affected sections should check the current guidance before applying.
• Other sections, including children of unmarried fathers, remain part of the same guidance.
