Citizenship Application Readiness — After ILR
Once you have secured Indefinite Leave to Remain (ILR), you may start planning for citizenship. This guide explains timelines, requirements, and evidence you need to be fully prepared. Use our plan your ILR timeline tool to understand when you can submit your application.
When you can apply for citizenship
Most applicants must wait 12 months after ILR before applying for British citizenship (naturalisation). Exceptions apply if you are married to a British citizen, in which case you may apply immediately after being granted ILR.
Tests & evidence required
The key requirements include:
- Life in the UK test pass certificate.
- Approved English language qualification or proof of exemption.
- Proof of residence in the UK for the qualifying period (usually 5 years, or 3 years if married to a British citizen).
- Evidence of “good character” (clean criminal record, tax compliance).

FAQs
Can I apply for citizenship immediately after ILR?
Only if you are married to a British citizen. Otherwise, most applicants must wait 12 months.
Do I need the Life in the UK test again?
No — if you already passed it for ILR, you don’t need to take it again for citizenship.
What is the “good character” requirement?
Applicants must show a clean criminal record, compliance with tax obligations, and no history of serious breaches of immigration law.
What if I have absences close to the limit?
Check rolling 12-month windows carefully with the ILR calculator. Excess absences can delay your eligibility for naturalisation.
