Key takeaways
- Indefinite Leave to Remain (ILR) gives you permanent residence in the UK, but it does not make you a British citizen.
- Naturalisation is the legal process of becoming a British citizen after holding ILR (or Settled Status) for at least 12 months – unless you’re married to a British citizen.
- ILR normally follows five years of continuous lawful residence, though certain routes (Long Residence, Innovator, Global Talent, etc.) differ.
- The Home Office has proposed increasing qualifying residence to 10 years for many work routes, but as of November 2025 no such change has yet taken effect.
- Fees from April 2025: ILR £3,029, Naturalisation £1,605 (plus biometrics & optional services).
- Only British citizens have a UK passport, voting rights, and are exempt from immigration control.
What is Indefinite Leave to Remain (ILR)?
Indefinite Leave to Remain (ILR), also known as “settlement”, allows non-UK nationals to live, work and study in the United Kingdom without time limit. Once granted, you are no longer restricted by visa conditions.
Eligibility overview
Most applicants qualify after five years’ continuous lawful residence in the UK under a qualifying visa route, such as:
- Skilled Worker Visa
- Global Talent Visa
- Spouse or Partner Visa
- Innovator Founder Visa
- Long Residence (10 years continuous lawful stay)
Other requirements:
- Absence limit: no more than 180 days outside the UK in any 12-month period (route-specific).
- Knowledge of Language and Life in the UK test.
- Good character requirement.
Note: The Government has announced plans to lengthen the qualifying period for many routes to 10 years, but this is not yet in force. If you apply now, current 5-year rules continue to apply.

What is Naturalisation?
Naturalisation is the final step – it converts your ILR (or Settled Status) into British citizenship. You become a British national, eligible for a passport and free from immigration control.
Main requirements
- Must hold ILR or Settled Status.
- Usually must have held ILR for 12 months before applying (unless married to a British citizen).
- Residence: normally 5 years in the UK before the application, with no more than 450 days abroad in those 5 years, and no more than 90 days in the final 12 months.
- Life in the UK test & English language at B1 or above.
- Good character and “sound mind”.
Once naturalised, you can:
- Hold a British passport;
- Vote in all UK elections;
- Enjoy full citizenship rights;
- Pass citizenship to children born abroad (depending on circumstances).

Choosing the right time to apply for citizenship
Some clients prefer to hold ILR long-term; others naturalise as soon as eligible. Consider:
- Travel patterns – frequent long absences can affect naturalisation eligibility.
- Tax residency – citizenship may influence global tax obligations.
- Dual citizenship – confirm your home country’s rules before applying.
- Children – naturalised citizens can often register children born abroad.
A solicitor can help you weigh these factors and time your application strategically.
Frequently Asked Questions (for voice search)
Does ILR make me a British citizen?
No. ILR grants permanent residence, but you remain a foreign national until you naturalise.
When can I apply for naturalisation after ILR?
Usually after 12 months holding ILR – unless you’re married to a British citizen, in which case you can apply immediately.
What are the residence limits for naturalisation?
Typically no more than 450 days outside the UK in the 5 years before application, and no more than 90 days in the final year.
Can I lose my ILR if I leave the UK?
Yes – being absent for more than 2 years can lead to loss of ILR. You may need to apply for a Returning Resident visa.
Are the rules changing?
The Home Office has proposed extending the qualifying period for ILR to 10 years for many routes. As of November 2025, these changes are not yet in force.
