Staying in the UK on a family visa usually means extending before your permission ends. Switching from another visa is possible only in limited cases, and a mistake on timing can leave you without lawful permission.
Information checked against the sources listed below on 10 October 2026. Rules, fees and thresholds change; this is general information, not advice on your case, and does not assess whether you qualify.
What the official guidance says.
- GOV.UK says you can extend or switch to a family visa inside the UK, but switching is limited to a spouse or partner, child, or parent.
- Visitors, and people with permission of 6 months or less, usually have to leave the UK to apply for a family visa. GOV.UK gives exceptions, including 6-month fiancé(e) visas and permission linked to a family court or divorce case.
- You cannot get a family visa if your family member is on a work or student visa.
- If you apply to extend or change your permission before it expires, your permission can continue while the application is decided (known as section 3C leave). Late or invalid applications do not qualify.
- While you have 3C leave, you cannot submit a new variation application.
- Victims of domestic abuse and bereaved partners may be able to settle under separate provisions (see family changes).
What usually decides the outcome.
- The date your current permission ends and the earliest date you can apply.
- Whether the requirement for your extension has changed since your last grant, including financial requirements.
- Whether your relationship or circumstances have changed since you last applied.
- Whether your application is valid and complete before you submit it.
