Advice on British citizenship, naturalisation and child registration. Check your eligibility, application timing and evidence with Knightsbridge.

British citizenship advice for you and your family

Becoming a British citizen is a significant step in making the UK your long-term home. It may follow years of work, family life and immigration applications, or involve securing citizenship for your children.

Knightsbridge Immigration helps you understand whether you qualify, when to apply and what evidence is needed. We review your circumstances before preparing the application, so you know where you stand and what needs attention before you commit to the next step.

Establish when you can apply

For many adults, the route to British citizenship is naturalisation after settlement.

If you hold Indefinite Leave to Remain or settled status, you will usually need to have held that status for 12 months before applying. If you are married to, or in a civil partnership with, a British citizen, that waiting period does not normally apply, provided you meet the other requirements.

We check your immigration status, residence history and the relevant application requirements to establish whether you are ready to proceed.

Check your residence and travel history

The timing of a citizenship application involves more than the date you received settlement.

Your absences from the UK and your physical presence at the beginning of the relevant qualifying period can affect eligibility. These details deserve particular attention if you travel regularly for work or spend extended periods visiting family overseas.

We review your travel history against the applicable requirements and help you identify gaps in your records. This allows the proposed application date to be considered alongside the evidence supporting it.

Prepare the evidence your application needs

A citizenship application brings together information about your identity, immigration history, residence and personal circumstances.

We explain the English language and Life in the UK requirements, including whether an exemption applies. We also consider the good character requirement and the information you need to disclose.

Our preparation includes reviewing supporting documents, checking consistency with the application and explaining the referee requirements. You will know which records to provide and which details need clarification.

Where something is missing or needs further consideration, we explain its significance before submission.

Assess your children’s citizenship position

Children’s citizenship applications follow different rules from adult naturalisation. Their position can depend on where and when they were born, their parents’ nationality and immigration status, and subsequent changes in the family’s circumstances.

We first consider whether a child is already British. If they are, an application to acquire citizenship may be unnecessary.

A child born in the UK may become eligible for registration when a parent later becomes settled or British, while the child is still under 18. Children born overseas require a different assessment.

We help couples and families plan these applications together, while checking each person’s eligibility separately.

Understand what happens after approval

For adult naturalisation applicants, approval is normally followed by a citizenship ceremony, where you receive your certificate of British citizenship.

A first British passport requires a separate application. Understanding these steps helps you plan around the completion of the citizenship process and any future travel.

We explain the next steps following the decision, including what the Home Office’s instructions mean for you.

Discuss your citizenship application

You do not need to have every document ready before contacting us.

Tell us about your current status, when you obtained settlement and whether you are applying for yourself or a child. If you are married to a British citizen or have spent significant time outside the UK, include those details.

We will confirm whether we can assist and explain the proposed work and fees before you instruct us. Where further preparation is needed, you will understand what to address before applying.
