Overview
Which British citizenship route may apply to you?
British citizenship is not a single application route. Some adults become British through naturalisation after obtaining permanent UK status. A spouse or civil partner of a British citizen may qualify under the shorter 3-year residence framework. Other people may be British automatically through a parent, while children who are not automatically British may be able to register.
The first step is therefore to identify the correct nationality route before preparing documents. Applying under the wrong category can lead to unnecessary fees, delays or a refusal, especially where the real issue is whether citizenship already exists automatically.
Immigration Visa Expert can review your immigration status, residence history, family connection and nationality evidence to identify the appropriate route before an application is prepared.

FAQs
British citizenship FAQs
What are the main ways to become a British citizen?
The main routes we advise on are adult naturalisation, naturalisation as the spouse or civil partner of a British citizen, citizenship through a British parent, and registration of a child as a British citizen. Some people are already British automatically and do not need to apply.
Do I need ILR or settled status before applying for British citizenship?
Most adult naturalisation applicants need permanent UK status before applying. The timing rules differ depending on whether the applicant is married to or in a civil partnership with a British citizen.
How long must I live in the UK before applying for British citizenship?
Residence requirements depend on the route. Adult naturalisation and spouse or civil-partner cases use different residence frameworks, while parentage and child-registration cases are assessed under different nationality provisions.
Can I apply for British citizenship through my parent?
Possibly. Some people are British automatically through a parent, while others may need registration. The answer depends on where and when you were born and how the British parent acquired citizenship.
Can a child apply for British citizenship?
Yes. A child who is not already British may qualify for registration depending on birth, parents' status, residence and other family circumstances.
How long does a British citizenship application take?
Many nationality applications are decided within around 6 months, although complex cases can take longer and additional information may be requested.
Can I travel while my British citizenship application is being considered?
A citizenship application does not normally prevent travel, but the applicant must continue to meet the relevant immigration and practical travel requirements while the application is pending.
Do I have to send my passport away for a British citizenship application?
Applicants normally provide identity and supporting evidence through the relevant application process rather than routinely surrendering their passport for the whole decision period.
Can I keep my existing nationality after becoming British?
The UK allows dual or multiple citizenship, but whether another country allows you to retain its nationality depends on that country's nationality law.
Does applying for British citizenship extend my immigration permission?
No. A citizenship application does not itself extend immigration permission. Anyone who does not already hold indefinite status should make sure their UK immigration position remains lawful while the application is pending.
