🇬🇧 Indefinite Leave to Remain (ILR) & British Citizenship Guide

Navigating the path to Indefinite Leave to Remain (ILR) and British Citizenship can be complex. This guide consolidates information from official sources to help you understand the general process and requirements. This website is not affiliated with the UK Home Office. Always verify information on GOV.UK.

All figures and facts on this page are sourced from official GOV.UK guidance and reviewed for accuracy, consistent with this site's handbook-verified approach across our other content. Fees and rules change, so always confirm the current details on GOV.UK before applying.

1. Indefinite Leave to Remain (ILR)

ILR is a way of settling in the UK permanently. It means you can live, work, and study in the UK without time restrictions. It also allows you to access public funds if you are eligible and to leave and re-enter the UK, although spending long periods outside the UK can lead to ILR lapsing.

The qualifying period depends on your immigration route and is commonly 3, 5 or 10 years.

Common ILR Routes & Qualifying Periods:

Check your eligibility and specific requirements on GOV.UK.

Key Requirements for ILR:

• Continuous Residence: You must satisfy the continuous residence requirements for your visa category, including limits on time spent outside the UK.
• Life in the UK Test: You must pass the Life in the UK Test. This website helps you prepare!
• English Language Requirement: You may meet the requirement through an approved English language test (SELT), an eligible degree taught in English, or by being exempt under the Immigration Rules. (See approved qualifications on GOV.UK)
• Application Form & Documents: Complete the correct online application form and provide all required supporting documents.

ILR Application Process & Fees:

Applications are made online via GOV.UK. As of July 2026, the standard ILR application fee is £3,226 per applicant (this applies across most settlement routes, including family, ancestry, and business/investor/talent categories). Dependants included on the same application each pay this fee individually. You can often choose between standard, priority, and super priority services for faster decisions, at an additional cost. Fees are reviewed periodically by the Home Office. Always confirm the current fee on GOV.UK before applying.

Check current fees on GOV.UK.

Processing Times:

Processing times vary depending on the application type and demand. Current estimated processing times are published on GOV.UK. Priority and super priority services are available for faster decisions at an additional cost.

Biometrics (UKVCAS):

Most applicants will need to attend a UKVCAS appointment to provide fingerprints, a photograph and supporting documents. You will be guided through the booking process after submitting your online application.

BRP & eVisa:

Most immigration status is now recorded digitally through an eVisa rather than solely on a physical Biometric Residence Permit (BRP). You should create a UKVI account to access your eVisa and prove your immigration status online.

Important: Don't Leave the UK While Your Application is Pending:

If you leave the UK while your ILR application is being processed, your application will generally be treated as withdrawn. Wait until you receive a decision before making any travel plans.

When ILR Can Lapse:

ILR can normally lapse if you remain outside the UK continuously for more than two years. If this happens, you would need to apply for a Returning Resident visa to re-enter and settle in the UK.

Common Reasons ILR Applications Are Refused:

GOV.UK guidance highlights several common, avoidable reasons ILR applications are refused:

• Exceeding the permitted absence limit: Spending too much time outside the UK during your qualifying period can break continuous residence.
• Incomplete or incorrect documentation: Missing evidence, expired documents, or documents that don't match the application form.
• Incorrect fee paid: Paying the wrong fee amount or for the wrong category can cause an application to be rejected as invalid.
• Suitability / good character issues: Criminal convictions, deception, or previous immigration breaches can lead to refusal on character grounds.
• Not meeting the English language or Life in the UK Test requirement: Failing to provide valid evidence of an approved SELT, qualifying degree, or a passed Life in the UK Test.
• Financial requirement not met: On routes with an income or maintenance requirement, insufficient evidence of funds can result in refusal.

If your application is refused, you may be able to apply for an administrative review or make a fresh application depending on your circumstances. Seeking legal advice is recommended.

Quick Glossary:

2. British Citizenship (Naturalisation)

After obtaining ILR, you can usually apply for British Citizenship through naturalisation. There are specific residency requirements you must meet.

Key Requirements for Naturalisation:

• Residency: Typically, you need 5 years of residency in the UK, including 1 year with ILR. You must also satisfy residence and absence requirements, including being physically present in the UK at the start of the qualifying period. If you are married to a British citizen, you may be able to apply for citizenship immediately after getting ILR, provided you meet other requirements.
• Good Character: Meet the good character requirement.
• Life in the UK Test & English Language: You will generally have already met these for ILR.
• Intention to Reside: Intend to continue living in the UK.

Dual Citizenship:

The UK allows dual citizenship, meaning you can become a British citizen and keep your existing nationality. However, whether you can keep your original nationality depends on the laws of your home country.

3. After Your Application

Citizenship Ceremony:

If your British Citizenship application is successful, you will be invited to attend a citizenship ceremony. After the ceremony, you can apply for a British passport.

British Passport:

Once you have attended your citizenship ceremony and received your certificate, you can apply for a British passport. This is a separate application processed by HM Passport Office.
