Indefinite Leave to Remain (ILR): A Complete Eligibility Guide

Indefinite Leave to Remain, commonly known as ILR or settlement, is the point at which most immigration journeys are heading. It removes the time limit on your stay in the UK, ends the cycle of visa renewals, and opens the door to British citizenship further down the line. But because eligibility depends heavily on which visa route brought you here, it’s easy to get the requirements wrong, and a mistake at this stage can be costly. This guide walks through what ILR actually requires, route by route.

What ILR Actually Gives You

Once granted, ILR allows you to:

• Live in the UK with no expiry date on your stay
• Work for any employer, or become self-employed, without sponsorship
• Study at any UK institution
• Access the NHS without paying the Immigration Health Surcharge
• Access public funds and benefits, if otherwise eligible
• Sponsor eligible family members to join you
• Apply for British citizenship later, once the naturalisation requirements are met

It’s a significant step, which is exactly why the requirements are checked so carefully.

The Core Requirements, Regardless of Route

Whatever visa route brought you to the UK, most ILR applications need to satisfy the same core conditions:

Continuous lawful residence. You need to have held valid immigration status throughout your qualifying period, with no gaps or breaches of your visa conditions.

The absence limit. For most routes, you cannot have spent more than 180 days outside the UK in any rolling 12-month period. Some routes, including certain family and long residence categories, apply the rules slightly differently, so it’s worth checking which absence rule applies to your specific route.

The Life in the UK Test. Unless you’re exempt (which includes applicants under 18 or over 65, and some other categories), you’ll need to pass this test before applying.

English language requirement. Most applicants need to demonstrate English at B1 level or above, through an approved test, a degree taught in English, or by being a national of a majority English-speaking country, unless exempt.

Good character. This covers criminal history, immigration compliance, and financial conduct, including debts to the UK government. It’s assessed throughout your qualifying period, not just at the point of application.

Qualifying Periods by Route

This is where things vary the most, and it’s the detail people most often get wrong. Typical qualifying periods include:

• Skilled Worker visa: 5 years
• Spouse or partner of a British citizen or settled person: 5 years
• UK Ancestry visa: 5 years
• Global Talent visa: 3 years in many cases
• Innovator Founder visa: 3 years, subject to business criteria
• Long residence route: 10 years of continuous lawful residence

Some categories, such as returning residents or certain investor and entrepreneur routes, follow different timelines again. If you’re unsure which route applies to your circumstances, that’s worth clarifying before you get close to your application date, not after.

How and When to Apply

You can apply for ILR up to 28 days before you complete your qualifying period, but not after your current leave expires. Applying late, even by a short margin, can mean falling into overstayer status, which creates a serious immigration breach and can undo years of otherwise lawful residence. This is one of the most common and most avoidable mistakes people make with ILR applications.

Applications are submitted online through the correct SET form for your route, followed by a biometric appointment. Processing for a standard decision can take several months, with a paid priority service available for those who need a faster outcome.

Where Applications Commonly Go Wrong

A few issues come up repeatedly with ILR refusals:

• Absences that exceed the permitted limit, sometimes without the applicant realising it until the count is done
• Gaps in lawful status during the qualifying period, even short ones
• Missing or incomplete evidence for route-specific requirements, such as salary or sponsorship documentation
• Applying under the wrong route entirely, particularly for those whose circumstances have changed during their time in the UK

Because the rules are applied strictly and a refusal can be difficult to reverse, it’s worth having your specific circumstances reviewed by a regulated adviser well before you plan to apply, rather than discovering an issue at submission.

Getting the Right Advice

Every ILR case depends on the specifics of your route, your residence history, and your documentation, so general guidance can only take you so far. If you’re approaching your qualifying period and want to make sure your application is built correctly the first time, speak to a regulated immigration adviser who can review your circumstances directly.
