UK ILR and Settlement for South Africans

Indefinite Leave to Remain, often called ILR or settlement, is the stage where a person can live, work and study in the UK without being limited by the expiry date of a visa.

For South Africans in the UK, ILR planning is usually relevant after time on a UK Ancestry visa, Skilled Worker visa, spouse or partner route, dependant route, long residence route, or another qualifying route.

The correct ILR strategy depends on the route, the dates, absences, evidence and any immigration history issues.

When can South Africans apply for ILR?

There is no single ILR date that applies to everyone. The qualifying period depends on the immigration route.

Common examples include:

Spouse or partner route: usually after 5 years continuously on the qualifying partner route, unless the person is on a 10-year route or another exception applies.
UK Ancestry visa: usually after 5 years on the UK Ancestry route, provided the settlement requirements are met.
Skilled Worker route: usually after 5 years on a qualifying work route, subject to salary, sponsorship and residence requirements.
Dependants: dependants may qualify in line with, or separately from, the main applicant depending on the route and dates.
Long residence: some applicants may qualify after a qualifying period of lawful residence, but the rules are technical and should be checked carefully.

Do not apply too early

Timing is important. Many ILR routes allow an application up to 28 days before the applicant meets the qualifying residence period.

Applying too early can lead to refusal. Waiting too long can create expiry and extension problems. If the current visa will expire before the applicant qualifies for ILR, an extension may be needed first.

UK Ancestry to ILR

South Africans with a UK-born grandparent often enter the UK on the UK Ancestry route. This visa is normally granted for 5 years and can lead to ILR where the requirements are met.

Important issues include:

the date the person entered the UK;
whether the person has completed 5 years on the Ancestry route;
absences from the UK;
whether the applicant worked or intended to work in the UK;
English language and Life in the UK evidence;
dependants applying with the main applicant; and
whether an Ancestry extension is needed before ILR.

Spouse or partner visa to ILR

A spouse or partner can usually apply for ILR after completing 5 years continuously on the qualifying family route as a partner.

Time as a fiancee or proposed civil partner does not normally count toward the 5-year partner settlement period. Time spent on other visa categories also may not count for partner-route ILR.

The application must normally deal with the relationship, cohabitation, financial requirement or adequate maintenance, accommodation, English language and Life in the UK test.

Skilled Worker to ILR

Skilled Worker settlement usually requires the applicant to still be sponsored in an eligible role, meet the relevant salary requirement, satisfy residence requirements, and provide the required employer confirmation.

Salary thresholds and occupation codes matter. A person who qualified for an initial Skilled Worker visa does not automatically qualify for ILR without checking the settlement requirements at the time of applying.

Absences from the UK

Absences can be one of the most important parts of an ILR assessment.

For several work and ancestry routes, continuous residence is assessed carefully and excessive absences can affect eligibility. The relevant period, date calculation and permitted exceptions need to be checked against the route being used.

For partner-route ILR, the residence analysis is different, but long or unexplained absences may still raise questions about whether the couple intended to live together permanently in the UK.

Before applying, applicants should prepare a full travel history and compare it against the route-specific ILR rules.

Life in the UK and English language

Most ILR applicants need to meet the Knowledge of Language and Life in the UK requirement unless exempt.

This usually means passing the Life in the UK test and proving English language at the required level. Some applicants can rely on nationality, an approved qualification, a previous accepted English test, age or medical exemption depending on the facts.

Applying with dependants

Dependants should not be treated as an afterthought.

Each family member’s qualifying period, current leave, absences, age, dependency, English or Life in the UK position and application timing should be checked individually.

Children who are close to turning 18 may need particular attention, because dependency and independent-life issues can become more important.

What if you are not ready for ILR?

If the applicant does not yet qualify for ILR, the correct answer may be an extension rather than a risky settlement application.

This can happen where absences are too high, the person entered the UK later than the visa start date, Life in the UK is not yet passed, salary evidence is not ready, or the spouse route financial requirement is not met.

In some cases, we can calculate the next compliant ILR window and prepare the extension strategy in the meantime.
