ILR vs Citizenship: Which Should You Apply For?

Updated 27 March 202610 min read

What you need to know

ILR and British citizenship both let you live and work in the UK without restrictions, but citizenship offers additional benefits: a British passport, voting rights, and permanent status that cannot be lost through absence. ILR is cheaper overall and does not require you to take a citizenship test or attend a ceremony, but it can be lost if you leave the UK for more than 2 years. The right choice depends on your travel plans, attachment to your current nationality, and long-term intentions.

Rights Comparison

Both ILR holders and British citizens can live, work, and study in the UK without restrictions. You can read about ILR rights on GOV.UK and citizenship through ILR. But there are important differences:

  • Right to work: Both ILR and citizenship give you unrestricted right to work in any job, including self-employment. No employer sponsorship required.
  • Access to public funds: Both allow access to the full range of public funds and benefits.
  • NHS access: Both give free access to the NHS without paying the Immigration Health Surcharge.
  • Voting: British citizens can vote in all UK elections. Commonwealth and Irish citizens with ILR can also vote in all elections. Citizens of other countries with ILR can only vote in local elections (in England) or devolved elections (in Scotland and Wales) in some cases.
  • Jury service: Both ILR holders and citizens can be called for jury service.
  • Standing for elected office: Only British, Commonwealth, and Irish citizens can stand for election to Parliament or local councils.

Travel and Passport

This is where the difference is most significant for many people.

  • British passport: Only citizens can hold a British passport. The British passport provides visa-free or visa-on-arrival access to over 180 countries, making it one of the most powerful passports in the world.
  • ILR holders travel on their home passport: Your travel freedom depends entirely on your home country's passport. If your passport has limited visa-free access, a British passport would be a significant upgrade.
  • Re-entry to the UK: British citizens can always enter the UK without question. ILR holders can also re-enter freely, but if they have been absent for more than 2 years, their ILR lapses and they cannot re-enter on that basis.
  • Consular protection: British citizens receive consular assistance from British embassies worldwide. ILR holders do not.

Risk of Losing Your Status

This is the most critical practical difference between ILR and citizenship.

ILR Can Be Lost

  • 2-year absence rule: If you spend more than 2 continuous years outside the UK, your ILR lapses automatically. You would need to apply for a Returning Resident visa to come back, which is not guaranteed.
  • Deportation: ILR holders can be deported if convicted of a serious criminal offence.
  • Revocation: ILR can be revoked in certain circumstances, such as if it was obtained by deception.

Citizenship Is Extremely Difficult to Lose

  • No absence rule: You can spend as long as you want outside the UK without losing citizenship.
  • Deprivation of citizenship: The Home Secretary can deprive someone of British citizenship only in very limited circumstances: if it was obtained by fraud or deception, or if the person's conduct is seriously prejudicial to the vital interests of the UK. This is extremely rare.

If you travel frequently, plan extended periods abroad, or may need to return to your home country for family or work reasons, citizenship provides much greater security than ILR.

Cost Comparison

  • ILR application: £2,885 (check current fees on GOV.UK)
  • Citizenship application (after ILR): £1,344
  • Total for both: £4,545
  • British passport (first adult): £82.50 (online)

Citizenship costs less than ILR, but it comes after ILR, so you pay for both over time. If money is tight, you can stay with ILR indefinitely and apply for citizenship when your finances allow.

Dual Citizenship Considerations

The UK fully allows dual (and multiple) citizenship. You do not need to renounce your existing nationality to become British.

However, your home country may not allow dual citizenship. If your country requires you to give up your nationality when you become a citizen elsewhere, you need to weigh whether a British passport is worth losing your original citizenship. Countries with restrictions include (but are not limited to) India, China, Japan, and several others. Check your country's rules carefully.

If your country does not allow dual citizenship, staying with ILR allows you to keep your original nationality while still living permanently in the UK — but with the risk of losing ILR through extended absence.

Passing Status to Children

  • Children born in the UK to ILR holders: Automatically British citizens at birth.
  • Children born in the UK to citizens: Automatically British citizens at birth.
  • Children born abroad to citizens: Usually British citizens by descent (first generation born abroad).
  • Children born abroad to ILR holders: Not automatically entitled to British citizenship or ILR. They would need to apply for a visa to come to the UK.

If you plan to have children abroad (or already have children abroad who may need to come to the UK), citizenship gives them a much clearer path to British status.

Which Should You Choose?

ILR May Be Enough If:

  • You do not plan to spend more than 2 years outside the UK
  • Your home country does not allow dual citizenship and you want to keep your nationality
  • You are not concerned about voting in UK general elections
  • Your home country's passport provides sufficient travel freedom
  • You prefer to save the additional £1,344 citizenship cost

Citizenship Is Advisable If:

  • You may need to spend extended periods abroad (more than 2 years)
  • You want a British passport for travel freedom
  • You want to vote in all UK elections
  • You want to pass citizenship to children born abroad
  • You want the security of a status that cannot be lost through absence
  • Your home country allows dual citizenship

Next Steps

If you have decided to apply for citizenship, see our guides:

If you have decided to stay with ILR, make sure you understand the rules for maintaining it, particularly the 2-year absence rule. If your plans change in the future, you can always apply for citizenship later — there is no deadline.
