You’ve Earned ILR – What’s Next?
Reaching Indefinite Leave to Remain (ILR) is a huge milestone. It marks stability, security, and the ability to call the UK your permanent home.
But for many, ILR is not the final step — it’s the beginning of a new chapter: British citizenship.
Citizenship gives you full rights to vote, hold a British passport, and live without immigration restrictions. In 2025, the Home Office continues to modernise the naturalisation process, but the key eligibility rules remain the same.
At AHJ Immigration, we guide clients who’ve achieved ILR through the final stage — turning settlement into citizenship with confidence.
When Can You Apply for British Citizenship?
In most cases, you can apply for British citizenship 12 months after obtaining ILR.
General Rule
- You must have held ILR (or Settled Status) for at least 12 months before applying.
- You must have lived legally in the UK for at least 5 years in total.
Exception for Spouses of British Citizens
If you’re married to or in a civil partnership with a British citizen, you can apply as soon as you receive ILR — no need to wait 12 months.
“Planning early helps avoid gaps or travel issues that might affect your residence calculation. Many clients wait too long after ILR and discover small details — like time spent abroad — can affect eligibility.”
— Baz Jabbar, Senior Immigration Adviser at AHJ Immigration

Tests and Documents You’ll Need
Applying for citizenship involves showing proof of residence, identity, and integration into UK life.
Key Documents
- Current passport and BRP (Biometric Residence Permit)
- Proof of ILR (Home Office approval letter)
- Evidence of residence (payslips, P60s, tenancy agreements, bank statements)
- Life in the UK Test certificate

Fees (2025)
The Home Office application fee remains £1,630 including the citizenship ceremony.
How to Apply for British Citizenship in 2025 – Step by Step
Step 1: Check Your Eligibility
Confirm your residence, absences, and ILR date. Small calculation errors can delay your application.
Step 2: Gather Documents and Pass Required Tests
Make sure your Life in the UK and English test certificates are valid and ready.
Step 3: Complete Form AN (Application for Naturalisation)
You can apply online through the Home Office website.
Step 4: Pay the Fee and Upload Documents
You’ll need to pay the fee and upload supporting documents using the UKVCAS service.
Step 5: Attend Biometrics Appointment
Book and attend an appointment to provide fingerprints and a photo.
Step 6: Wait for Decision
Most applications take 3 to 6 months, though some may take longer if checks are needed.
Step 7: Citizenship Ceremony
Once approved, you’ll receive an invitation to attend a local citizenship ceremony — a symbolic final step where you take the Oath of Allegiance and receive your certificate.
Common Reasons for Delays or Refusals
Even strong applications can face setbacks if small details are missed.
1. Excessive Absences
Exceeding permitted travel days (especially in the final 12 months) is a common reason for refusal.
2. Unpaid Taxes or HMRC Errors
Any unresolved tax discrepancy can cause a delay while checks are made.
3. Failing to Disclose Criminal Convictions
Even minor offences or driving penalties must be declared.
4. Incorrect Referee Information
Referees who don’t meet the Home Office’s criteria can invalidate the application.
5. Applying Too Early After ILR
Submitting your citizenship application before 12 months have passed (if required) will lead to rejection.
Why Plan Ahead After ILR
The period immediately after receiving ILR is the best time to start planning your citizenship application.
Here’s how to stay prepared:
- Keep travel records updated for each trip abroad.
- Retain proof of residence like utility bills, tax letters, or council tax statements.
- Renew your English test certificate if expired.
- Ensure your BRP and passport details match exactly.
These small actions now can save months of delay later.
Dual Citizenship in 2025
The UK allows dual nationality, meaning you can keep your original citizenship unless your home country restricts it.
Always check with your country of origin before applying.
Some countries (such as India and China) do not allow dual citizenship, while others (like Pakistan, Canada, and the US) do.
AHJ Immigration can advise on the implications of dual nationality for your personal situation.
