Indefinite Leave to Remain in the UK — The Complete Guide for African Migrants

Five years. That is how long most Skilled Worker Visa holders wait before they can apply for Indefinite Leave to Remain — what is commonly called ILR or "settlement." It is the most significant immigration milestone in the UK journey. Once you have ILR, you can live and work in the UK without any immigration conditions, you are no longer tied to a specific employer, and you are one year away from British citizenship.

It is also an application that trips people up — not because the requirements are secret, but because certain mistakes are easy to make over five years without realising their consequences. The absences rule. The salary requirement. The continuous residence calculation. The Life in the UK test that most people leave too late.

This guide covers all of it.

What ILR actually gives you

Before the requirements, it is worth being clear about what you are working toward.

Indefinite Leave to Remain means:

• You can live and work in the UK indefinitely — no visa, no expiry date
• You can work for any employer in any role without sponsorship
• You can be self-employed or run your own business
• You can access public funds (benefits, social housing) on the same basis as a British citizen
• You are no longer subject to immigration control for everyday purposes
• You become eligible to apply for British citizenship after 12 months

What ILR does not mean:

• You cannot vote in UK general elections (citizenship gives you that)
• Your ILR lapses if you spend more than 2 consecutive years outside the UK
• If you have a criminal conviction, ILR can be revoked in serious circumstances

The five main requirements

1. The continuous residence requirement: 5 years

You must have spent 5 years in the UK on a qualifying visa. For Skilled Worker visa holders, this means 5 years from the date your first Skilled Worker (or Tier 2) visa was granted.

The 5 years must be "continuous" — but continuous does not mean you cannot leave the UK. It means you cannot have any gaps in your qualifying visa coverage and you must meet the absences requirement below.

2. The absences requirement: 180 days per year maximum

This is where many people are caught out.

In any 12-month period during your 5 years, you cannot have been outside the UK for more than 180 days. The 12-month period is rolling — it is not the calendar year, but any 12-month period.

180 days sounds like a lot. It is approximately 6 months. But if you have family in Africa, attend weddings and funerals, take summer holidays home, and occasionally work on international projects, those days add up faster than people expect.

What to do: Keep a record of every trip you take outside the UK. Date of departure, date of return. Count your days outside the UK for every rolling 12-month period. If you are approaching 180 days in any period, you need to know before you travel, not after.

3. The salary requirement

For Skilled Worker ILR applicants, you must meet the current salary threshold at the time of your ILR application. In 2025, this is the same as the current Skilled Worker minimum — generally £38,700 or the going rate for your occupation code, whichever is higher.

If your salary has dropped below this threshold (perhaps you changed roles or took a pay cut), you will need to address this before applying. If your occupation code has changed, you need to check that your current role still qualifies.

4. The Life in the UK test

The Life in the UK test is a 24-question multiple-choice test that all ILR applicants must pass. You have 45 minutes. You need 75% (18 out of 24) to pass.

The test covers British history, culture, values, laws, and institutions. It draws from the official handbook: Life in the United Kingdom: A Guide for New Residents — the 3rd edition specifically.

Do not underestimate this test. The questions include genuinely difficult historical and cultural details. "In which year did women over 30 gain the right to vote in the UK?" "What is the name of the document signed by King John in 1215?" Questions about the NHS structure, parliamentary process, patron saints, and key historical events appear regularly.

The test costs £50 and must be taken at an approved test centre. You must bring your passport and booking confirmation. If you fail, you can retake (paying £50 again) after 7 days.

How to prepare:

1. Buy or borrow the official handbook — the 3rd edition, published by TSO. Read it twice.
2. Use the free practice tests at lifeintheuk.net and officiallifeintheuk.co.uk
3. Set yourself the condition of passing 5 practice tests consecutively before booking the real test
4. Book the real test 2–3 months before you plan to submit your ILR application

Most people who fail did not read the handbook carefully enough. Most people who pass read it twice and practiced consistently.

Case study: Tendai's ILR journey — and the absences problem he nearly didn't notice

Tendai is a 38-year-old civil engineer from Harare, now based in Bristol. He arrived in the UK on a Skilled Worker Visa in October 2019. By late 2024 he was approaching his 5-year mark and began preparing his ILR application.

When he sat down to calculate his absences, he discovered a problem.

Between September 2021 and September 2022, he had been to Zimbabwe three times: two weeks at Christmas, three weeks in April for his father's funeral and the associated family obligations, and eight weeks over the summer when he took his children back to spend time with their grandparents. Total for that 12-month period: 91 days.

Then between July 2022 and July 2023: a 2-week work trip to South Africa (his employer had a project there), three weeks in Zimbabwe at Christmas, three weeks in Zimbabwe at Easter, and six weeks over summer. Total: 98 days.

Separately, between December 2022 and December 2023 (overlapping the above periods), the combined December-to-December window showed 195 days — over the limit.

This was a rolling period problem. Two of the above trips overlapped into a single 12-month window that exceeded 180 days.

What Tendai did: He consulted an immigration lawyer. The lawyer's assessment: the excess was by 15 days in one rolling period. In practice, the Home Office might exercise discretion for absences related to a parent's funeral and other compassionate circumstances, particularly where the overall pattern of absence was reasonable.

Tendai submitted his ILR application with a detailed covering letter explaining the circumstances of each trip, including a death certificate for his father. His application was approved.

The lesson: Track your absences from day one. And if you are close to or over the limit, get legal advice before you apply — do not assume it will be fine or that you will figure it out at the application stage.

The ILR application process

Cost: £2,885 per person (2025). This is per adult — dependants applying at the same time pay separately.

Method: Online application (SET(O) form for Skilled Worker route), then an appointment at a UK Visas and Immigration (UKVI) office for biometrics. There is a "super priority" option for next-day decisions for an additional £1,000.

Documents you will need:

• Passport (and all previous passports covering your 5 years in the UK)
• Life in the UK test pass certificate
• Current employment details, payslip, and employment letter
• English language evidence (your original visa evidence is usually sufficient if you used IELTS — it does not expire for ILR purposes)
• Travel history document showing all your trips in and out of the UK for 5 years
• P60s (annual tax summaries) for the years you have been in the UK

The travel history is important. You should be able to produce a table of every trip: date of departure from UK, date of return, destination, reason. Build this from your passport stamps, boarding passes, and calendar. The Home Office has its own records but applicants who show they have already calculated their absences carefully tend to have smoother applications.

After ILR: the path to British citizenship

After holding ILR for 12 months, you can apply for naturalisation as a British citizen. Requirements:

• Held ILR for 12 months
• Resided in the UK for 5 years before the application (the ILR period counts)
• Not been outside the UK for more than 450 days in the 5 years before the application, and not more than 90 days in the final 12 months
• Good character (no serious criminal convictions, no deception in immigration applications)
• Life in the UK test (if you passed it for ILR, you do not need to retake it)
• English language (same as ILR — already demonstrated)

The naturalisation fee in 2025 is £1,630 per adult.

What British citizenship gives you that ILR does not:

• A British passport — one of the strongest travel documents in the world (visa-free access to 186 countries)
• The right to vote in all UK elections
• ILR can lapse if you spend 2 consecutive years abroad; British citizenship cannot be lost by absence
• The right to pass citizenship to your children born abroad

Dual nationality: Zimbabwe recognises dual nationality. You can hold a Zimbabwean and British passport simultaneously. This is genuinely valuable — the combination of a Zimbabwean and British passport gives you remarkable flexibility for travel across both Africa and Europe.
