How long does a child's British citizenship registration take?
If you have registered your child as a British citizen and are still waiting, a wait of a few months is completely normal. The Home Office's published aim is to decide nationality applications — including a child's registration on form MN1 — within 6 months of receiving a valid application. So a child application submitted in March, with biometrics enrolled later that same month, is well within the usual window by June. Around three months of waiting is expected, not a red flag.
This post explains the standard timeline, why young children skip the tests adults must take, what can stretch the wait, and what to do if you pass the 6-month mark.
- The Home Office service standard is to aim to decide nationality applications within 6 months of a valid application.
- You'll usually get a decision inside 6 months; if yours will take longer, you should be told before the 6 months are up.
- A wait of around 3 months (e.g. March to June) is normal and not a concern.
- Young children do not sit the Life in the UK test or an English language test.
- Children under 18 are registered (commonly via form MN1), not naturalised.
The 6-month service standard is the number that matters
For child registration, the Home Office sets a service level agreement of 6 months. Its guidance for nationality applicants puts it plainly: "You'll usually get a decision within 6 months — some applications can take longer. If yours will take longer you'll be told before 6 months have passed."
That means the relevant question is not "why is it taking three months?" but "are we still inside the 6-month window?" In a March-to-June scenario, you clearly are. Many straightforward child applications are decided faster than six months, but six months is the benchmark the Home Office holds itself to — and the point at which a wait moves from normal to worth chasing.
This is general information, not legal advice. The headline expectation: the Home Office aims to decide nationality applications, including a child's registration, within 6 months of a valid application. A wait of roughly three months from submitting biometrics is normal and not a cause for concern. Only once you pass six months without a decision (and without being told it will take longer) does it become worth actively chasing.
Why your child skips the tests adults must take
If you've been through citizenship for yourself, you may be bracing your child for the same hoops. You don't need to. The Life in the UK test is required only for applicants aged 18 to 64, and the English language requirement applies only to those aged 18 or over. A two-year-old falls well below both thresholds, so neither applies.
This is one of the practical differences between an adult's naturalisation and a child's registration. Children under 18 are registered as British citizens — usually on form MN1 — rather than naturalised, and the process is built around the child's eligibility (often through a parent's status), not language ability or knowledge of UK life. If you want the bigger picture of routes for adults and children, the British citizenship guide breaks it down.
What can stretch the timeline beyond the norm
Most child applications run smoothly, but some take longer because the Home Office needs to look more closely. Common reasons include:
- Further enquiries — the caseworker asks for extra documents or clarification.
- A more complex history — for example, gaps or questions about a parent's immigration record, or about how the child qualifies.
- Verification checks that simply take time to complete.
If any of these apply, the Home Office should keep you informed and, where a case will exceed six months, tell you before that point is reached. Responding quickly and fully to any request for information is the single most useful thing you can do to keep things moving.
What to do if you pass the 6-month mark
If your child's application goes beyond six months with no decision — and you haven't been told it will take longer — it's reasonable to chase it:
- Have your reference number ready and check any emails or letters for updates first.
- Contact UK Visas and Immigration using the GOV.UK contact tool to ask about the status of the application. Note that staff generally can't tell you exactly when a decision will come.
- Escalate if needed — if a long delay continues with no explanation, you can raise a formal complaint through GOV.UK, and some applicants seek independent immigration advice.
- Don't submit a duplicate application. Reapplying rarely speeds things up and can cause confusion or further delay.
For a side-by-side sense of how citizenship timelines work, see how long British citizenship by naturalisation takes and, if you're weighing the timing of a child's case against a parent's, registering a child on form MN1 alongside a parent or waiting.
The short version
March application, March biometrics, still waiting in June? That's a normal three-month wait against a 6-month service standard. Your child doesn't need the Life in the UK test or an English test. Keep your documents to hand, respond promptly to any Home Office request, and only start chasing once you pass six months.
