Can my child still remain on the dependant visa at 18?

What happens to a dependant visa when a child turns 18?

Turning 18 does not automatically cancel a child’s UK visa or prevent them from continuing as a dependant. However, turning 18 is an important dividing line under the Immigration Rules. Whether the young person can apply – or continue to apply – as a dependant will depend on when the application is made, their previous immigration permission and whether they are living independently.

This article explains the principal rules only. Each individual visa route may impose additional requirements, which should always be checked before submitting any application.

1. First visa application was made before the child has turned 18

For most dependent-child routes, a person making their first application must be under 18 on the date of submission.

If the application is submitted while the applicant is 17, but they turn 18 before the Home Office makes a decision, the application should ordinarily be assessed as though they are still under 18. The decisive date is therefore usually the date on which a valid application was made – not the date of the decision.

In this scenario, timing is critical. Delaying a first application until after the applicant’s eighteenth birthday may mean that they no longer qualify as a dependent child under the intended route.

2. Can someone aged 18 or over remain a dependant?

In many instances, yes. A person who is already 18 or older may continue to apply as a dependent child if they were previously granted permission as the dependent child of the same parent or parents.

The previous permission will ordinarily need to be valid on the date of the new application or to have expired no more than 14 days before that, subject to limited exceptions. An adult child who has never previously held permission as that parent’s dependant will usually be unable to make a first dependent-child application after turning 18.

Accordingly, turning 18 does not by itself bring existing dependant status to an end. The greater risk arises at the next extension or settlement application, when the applicant must demonstrate both continuity of status and continuing dependency.

3. The “independent life” requirement

A dependent child must not be leading an independent life. This requirement applies irrespective of whether the applicant is under or over 18.

In broad terms, the applicant must:

• not have a spouse, civil partner or partner in a relationship comparable to marriage; and
• normally live with their parent or parents, unless they live elsewhere because they are undertaking full-time education, such as at boarding school, college or university.

Turning 18, attending university or living in student accommodation does not necessarily establish an independent life. The Home Office will consider the substance of the arrangements, including the applicant’s relationship status, home address, financial support and reasons for living away from the family home.

Evidence may include bank statements, proof of parental financial support, correspondence showing that the family home remains the applicant’s permanent address, and evidence of full-time study and term-time accommodation.

4. What if the child has moved out or started working?

Moving out or taking employment does not invariably end dependency, but it may make the application more difficult.

A young person who has formed their own family unit, lives permanently away from their parents and supports themselves is more likely to be treated as leading an independent life. By contrast, a student who lives away during term time, returns to the family home and remains financially supported by their parents may still qualify as a dependant.

5. Does turning 18 affect settlement?

An applicant aged 18 or over may still qualify for settlement as a dependent child on certain routes, but they will ordinarily need to show that they previously held permission as a dependent child and continue to satisfy the relevant dependency requirements.

Settlement rules vary for different immigration routes. The requirements applying to the dependants of workers, partners, persons with UK Ancestry permission, members of HM Armed Forces and persons on protection-related routes are not identical. The parent’s immigration status, the timing of the family’s applications and the child’s previous grants of permission may all be material.

6. Does an existing visa expire on the eighteenth birthday?

Normally, no. An immigration permission does not generally expire merely because the holder turns 18. It remains valid until the stated expiry date, unless it is cancelled for another reason.

The eighteenth birthday becomes particularly important when the person makes their next application. At that stage, they must qualify under the rules applicable to an adult dependent child or apply under a different immigration route.

7. When might a different visa route be needed?

If the young person cannot satisfy the requirements for continued dependant status, they may need to consider another route, such as a student visa or, where eligible, a work route.

Switching routes can affect the person’s qualifying period for settlement, the conditions attached to their permission and the evidence they must provide. The options should therefore be considered before the current permission expires.

8. Practical steps before the child turns 18

1. Check the exact visa route: do not assume that every dependent-child category uses identical rules;
2. Confirm the application deadline: if this is the child’s first dependant application, it may be essential to submit it before their eighteenth birthday;
3. Preserve continuity: apply before the current permission expires wherever possible;
4. Document continuing dependency: retain evidence of financial support, living arrangements, education and that the child continues to live in the family home;
5. Review any change in circumstances: marriage or a similar type of relationship, permanent departure from the family home or financial independence may affect eligibility;
6. Consider settlement strategy early: changing immigration routes may alter the time required to qualify for indefinite leave to remain.

Frequently asked questions

Does a dependant child’s UK visa automatically end when they turn 18?

No. Existing immigration permission will normally remain valid until its stated expiry date. Turning 18 becomes particularly relevant when the young person makes their next application to extend their permission to stay or apply for settlement in the UK.

What happens if the child applies at 17 but turns 18 before the Home Office decides the application?

Where a valid dependent-child application was made before the applicant turned 18, the Home Office should ordinarily assess the age requirement as though the applicant remained under 18. The date of application is therefore critical.

Can an 18-year-old make a first application as a dependent child?

Generally, not under the standard dependent-child rules. A person aged 18 or over will generally need to have previously held permission as the dependent child of the same parent or parents. Some routes have specific provisions or exceptions, so the applicable Immigration Rules must be checked.

Can a child over 18 extend their dependant visa?

Potentially, yes. They will usually need to show that they were previously granted permission as the dependent child of the same parent or parents, that their immigration status has remained sufficiently continuous and that they are not leading an independent life.

Can an adult child remain a dependant while attending university?

Yes. Living away from the family home to attend boarding school, college or university as part of full-time education does not necessarily mean that the applicant is leading an independent life. Evidence should show that the arrangement is connected to education, and that the applicant remains part of the parental family unit.

Can an adult dependent child work?

Employment does not automatically prevent continued dependant status, provided the person’s immigration conditions permit work. However, substantial employment, financial self-sufficiency and permanent residence away from the parents may support a conclusion that the applicant is leading an independent life. The circumstances must be considered as a whole.

What does “not leading an independent life” mean?

Broadly this means that the applicant must not have a spouse, civil partner or other similar partner and must normally be living with their parent or parents, except where they live elsewhere for the purposes of full-time education. The Home Office may consider relationship status, accommodation, financial support, education and the applicant’s continuing connection with the family home.

Does marriage affect dependent-child status?

Yes. Being married, in a civil partnership or in another similar type of relationship will ordinarily mean that the independent-life requirement will not be met, and this person will generally be unable to continue as a dependent child.

What evidence shows that an adult child remains dependent?

Relevant evidence may include proof of parental financial support, bank statements, university or college enrolment records, term-time accommodation documents, correspondence addressed to the applicant at the family home and evidence that the applicant regularly returns to the parental household and remains part of it.

Can a child aged 18 or over apply for settlement with their parents?

Possibly. Eligibility depends on the particular immigration route, the applicant’s previous dependant permission, the parent’s status and whether the applicant continues to meet the relevant dependency requirements. Settlement provisions vary for different routes and should be checked carefully.

What if the adult child no longer qualifies as a dependant?

They may need to apply under another immigration category, such as a student visa or an eligible work route. Switching routes can affect conditions of stay and the period required for settlement, so the alternatives should be reviewed before the existing permission expires.

Should the application be submitted before the child’s eighteenth birthday?

If this is the child’s first application as a dependant, submitting a valid application before their eighteenth birthday may be decisive. Families should confirm the route-specific requirements and prepare the supporting evidence well in advance.

Conclusion

A child’s eighteenth birthday does not automatically terminate their UK immigration status. A first dependent-child application should ordinarily be made before the applicant turns 18. Someone who is already 18 or over may often continue as a dependant if they previously held dependent-child permission for the same parent or parents and have not started living independently.

The correct analysis is route specific and fact sensitive. Families should review the position well before the eighteenth birthday or the expiry of the child’s current permission, whichever occurs first.
