Indefinite Leave to Remain vs British Citizenship: What’s the Difference?

For many people building a life in the UK, two major milestones stand out: achieving Indefinite Leave to Remain (ILR) and eventually applying for British Citizenship. While both grant long-term security, they offer very different rights, responsibilities, and levels of permanence. 

If you’re unsure which status to pursue—or whether you should move from ILR to citizenship—this guide explains the key differences and helps you decide which option best fits your long-term plans.  

What Is Indefinite Leave to Remain? 

Indefinite Leave to Remain gives you the right to live, work, and study in the UK without time restrictions. Many migrants reach ILR after five years on a qualifying visa route (for example, Skilled Worker, Spouse, or Innovator). 

ILR is essentially permanent residence, but it is not the same as being a British national. 

Key Rights with ILR 

• Live and work in the UK without immigration restrictions 

• Access the NHS and public services 

• Study in the UK without international fees (in many cases) 

• Sponsor some family members to join you. 

Limitations of ILR 

Although secure, ILR is not the final step: 

• You can lose ILR if you have long absences 

• You cannot hold a British passport 

• You cannot vote in general elections 

• Some jobs requiring “British citizenship” remain off-limits 

• You may still be subject to deportation in certain circumstances. 

What Is British Citizenship? 

British Citizenship is the highest form of legal status in the UK. Once granted, it gives you full rights as a UK national including the ability to apply for a British passport. 

Most people become eligible for citizenship 12 months after obtaining ILR, provided they meet the residence and good character requirements. 

Key Rights with British Citizenship 

• Hold a British passport 

• Vote in all UK elections 

• Access consular support from UK embassies abroad 

• Enjoy unlimited time outside the UK without losing status 

• Access to certain jobs restricted to British nationals 

Restrictions or Considerations 

• Some nationalities do not allow dual citizenship, meaning you may need to give up your current nationality 

• The application involves stricter checks 

• You may need to attend a citizenship ceremony 

ILR vs British Citizenship: Key Differences at a Glance 

Eligibility: How Do You Qualify? 

To Qualify for ILR 

Requirements depend on the visa route, but typically include: 

• 5 or 10 years of lawful residence  

• Meeting salary/maintenance requirements (if applicable) 

• Continuous residence with limited absences 

• Life in the UK Test 

• B1 English level 

To Qualify for British Citizenship 

Most applicants must: 

• Hold ILR for 12 months (unless married to a British citizen) 

• Meet strict residence requirements 

• Have good character (clean immigration and criminal record) 

• Pass the Life in the UK Test 

• Meet the B1 English requirement 

• Intend to make the UK their home 

Which Option Is Best for You? 

Choose ILR if… 

• You want security but aren’t ready to change nationality 

• Your home country doesn’t allow dual citizenship, and you don’t want to give up your current passport 

• You’re undecided about long-term commitment to the UK. 

Choose British Citizenship if… 

• You plan to live in the UK permanently 

• You want full political rights, including voting 

• You travel frequently and want the strength of a British passport 

• You want to eliminate the risk of losing your status due to long absences 

• You want your children to automatically be British at birth (if born after citizenship is granted) 

Final Thoughts: ILR Is Security, Citizenship Is Belonging 

Both ILR and British Citizenship provide stability, but citizenship goes a step further by offering absolute permanence and full participation in UK life. 

Think of it this way: 

• ILR = the right to stay 

• British Citizenship = the right to belong fully 

Your choice depends on your long-term goals, family circumstances, and how closely you want to tie your future to the UK.
