Indefinite Leave to Remain (ILR)

Indefinite Leave to Remain (ILR) is a form of settlement that allows you to live and work in the UK without time restrictions. It is a key milestone for many migrants and often the final step before applying for British citizenship.

If you have lived in the UK under a qualifying visa for the required period and meet the relevant criteria, you may be eligible to apply for ILR. At Mowbray Advisory, we provide clear, OISC-regulated guidance to help you understand your eligibility and prepare a strong application.

What Does Indefinite Leave to Remain Allow You to Do?

Once granted ILR:

  • You can live and work in the UK without visa restrictions

  • You can access public services as a settled person

  • You can leave and re-enter the UK (subject to absence rules)

  • You may become eligible to apply for British citizenship

However, ILR can be lost if you remain outside the UK for extended periods.

Who Can Apply for ILR?

Eligibility depends on the visa route you have held. Common pathways include:

  • Skilled Worker Visa (typically after 5 years)

  • Spouse / Partner Visa

  • Long Residence (10 years lawful residence)

  • Refugee or humanitarian protection

  • Certain business and talent routes

Each route has different qualifying periods and requirements.

Key ILR Requirements

Continuous Residence

You must have lived in the UK for the required qualifying period without exceeding permitted absences.

Absence Limits

Absence limits vary by route. Excessive time outside the UK can affect eligibility.

Life in the UK Test

Most applicants must pass the official Life in the UK test unless exempt.

English Language Requirement

You may need to demonstrate English language proficiency at the required level.

Good Character

Applicants must show compliance with immigration law and have no serious criminal record.

The exact requirements depend on your immigration history and visa category.

ILR Application Process — Overview

While each case differs, the ILR process generally includes:

  1. Confirming eligibility under the correct route

  2. Gathering supporting documentation

  3. Completing the online ILR application form

  4. Submitting biometrics

  5. Awaiting a decision from UKVI

Processing times vary depending on route and service type.

Common Issues in ILR Applications

Applications may be delayed or refused due to:

  • Miscalculated absence days

  • Incorrect qualifying period

  • Missing or inconsistent documentation

  • Failure to meet Life in the UK or English requirements

  • Previous immigration breaches

Careful preparation can significantly reduce risk.
