British Citizenship and Naturalisation Applications
Naturalisation is the process by which many adults apply to become British citizens. British nationality and naturalisation are citizenship matters. They are separate from ILR, although many applicants must first hold ILR or settled status.

Naturalisation Is a Citizenship Application
British nationality law is separate from immigration settlement. ILR or settled status may be the foundation for a later citizenship application, but naturalisation has its own tests: residence, absences, future intentions, Life in the UK, English language and good character.
We assess whether you are ready to apply now or whether waiting would reduce the risk of refusal.
Settlement Comes First for Many Applicants
Most adult naturalisation applicants must hold ILR, indefinite leave to enter or settled status before applying. That settled status is not citizenship. Citizenship is only obtained if the naturalisation application is granted and the applicant completes the citizenship ceremony where required.
What We Review
| Requirement | What we check |
|---|---|
| Status | Whether you hold ILR, settled status or another qualifying status. |
| Residence and absences | Whether your days outside the UK fit the relevant 3-year or 5-year period. |
| Good character | Criminality, overstaying, illegal entry, deception, illegal working, tax and immigration history. |
| Evidence | Passports, travel records, referee details, tests, status evidence and explanation letters. |
Good Character Needs Care
Home Office nationality decisions can be strict where there has been adverse immigration history, including illegal entry, overstaying, breach of conditions, deception or illegal working. A citizenship application should not be filed as a formality simply because a person has ILR.
Frequently Asked Questions
Is naturalisation the same as British citizenship?
Naturalisation is one route by which an adult can become a British citizen. British nationality is the wider legal area covering citizenship, registration, descent and related routes.
Is ILR the same as naturalisation?
No. ILR is settlement. Naturalisation is a later citizenship application for many adults.
Do I always need to wait 12 months after ILR?
Many applicants must wait 12 months after ILR or settled status. Spouses and civil partners of British citizens may be treated differently, but they must still meet the other citizenship requirements.
Should I apply if I have adverse immigration history?
Get advice before applying. Good character issues can lead to refusal and can affect future applications.
