You can vary a UK visa application by submitting a new one before a decision is made on the first — it will then be handled under Rule 34BB of the Immigration Rules, meaning the Home Office only considers the most recently submitted application.
In short
- Rule 34BB: submitting a second application before a decision on the first means only the newest one is considered — the first simply stops being active.
- The new application must independently meet the validity requirements — an earlier application on file doesn’t make this any easier.
- Biometrics for the previous application must be given — without them, Section 3C status is not activated.
- If biometrics were given on time, the application fee is not refunded even if the application is varied or withdrawn — but the IHS fee is always refunded.
- If the Home Office cannot identify the most recent application and no confirmation arrives within 14 days, all submitted applications are treated as invalid.
What is varying an application under Rule 34BB
Varying an application means changing a visa or leave-to-remain application that has already been submitted, while no decision has yet been made on it. This mechanism is governed by Rule 34BB of the UK Immigration Rules.
The rule applies when an applicant already has an outstanding application — either for entry clearance or leave to remain — on which a decision has not yet been issued.
Which application gets considered if you submit a second one before a decision on the first
If a second application is submitted before a decision has been made on the first, only the most recent one is considered — the first is not refused by a separate decision, it simply stops being an active application. This is set out in Immigration Rule 34BB, sub-paragraph (1): the Home Office is required to consider only the most recently submitted application.
If a second application is submitted before a decision has been made on the first, only the most recent one is considered — the first is not refused by a separate decision, it simply stops being an active application.
This does not exempt the applicant from meeting the requirements for the new application. It must independently satisfy the validity requirements and the right to apply — having already submitted an earlier application does nothing to lower the bar for the second one.
When a second application is submitted before a decision on the first, only the latest is considered. But it still has to fully meet the validity and right-to-apply requirements on its own terms — having an earlier application on file doesn’t make any of this easier.
Requirements for the new application: validity and eligibility
A new application is not exempt from the standard requirements: it must meet the application validity requirements that apply to any UK visa or leave-to-remain application.
This applies equally to a second application submitted before a decision on the first. Rule 34BB does not directly address eligibility requirements — that is, whether the applicant meets the conditions of a specific route — it governs only the validity of the application itself. But that does not mean eligibility can be ignored: it is assessed when the application is decided, and the second application must meet it just as any standalone application would.
Fingerprints and the 10-working-day window for Section 3C
Under the current rule, biometrics for the previous application must be provided — without this, Section 3C status is not activated. Previously, a different system applied: if an applicant hadn’t given biometrics and then withdrew or varied their application, all fees paid were refunded in full. The Home Office concluded this was being exploited, with applicants deliberately delaying their biometric appointments.
The 10-working-day window is not the standard biometrics deadline (the usual periods are 15 working days via a Service and Support Centre or 45 working days via UKVCAS) — it is the shortened period within which the Home Office can require an error or omission in the application to be corrected. If biometrics are provided within the deadline set for the applicant, the Home Office keeps the application fee even if the application is later withdrawn or varied. The IHS fee is always refunded separately, regardless.
The practical takeaway: don’t try to vary an application before biometrics have been provided. Giving biometrics is a mandatory step before any variation, and it cannot be skipped.
Without giving biometrics on the previous application, Section 3C status is not activated. It’s not advisable to vary an application before biometrics have been given.
Fees: IHS, the application fee, and refund conditions
Two payments are taken when an application is submitted: the Immigration Health Surcharge (IHS) and the fee for processing the application. What happens to this money if an application is varied or withdrawn depends on whether biometrics were provided within the deadline.
| Situation | Application fee | IHS fee |
|---|---|---|
| Biometrics not provided, application withdrawn or varied (previous rule) | Refunded in full | Refunded |
| Biometrics provided on time, application then varied or withdrawn (current rule) | Kept by the Home Office, not refunded | Refunded |
This is why the new rule was introduced: if biometrics are provided within the set period, the application fee is retained even if the application is subsequently varied or withdrawn. This rule does not affect the IHS fee — it is refunded regardless of whether biometrics were given or not.
What happens to the fee and the IHS surcharge when an application is varied
How the refund rules changed after biometrics are given on time
- Application fee
- IHS fee
If biometrics were given on time and the application is later varied or withdrawn, the Home Office will not refund the processing fee. The IHS fee is refunded regardless.
If the Home Office cannot identify the most recent application
In practice, the Home Office does not always check with the applicant which of the submitted applications should be treated as current — often it simply proceeds on the assumption that the most recent one should be considered. But if the submission dates are close together and the latest application cannot be clearly identified, the department sends a request for confirmation.
The applicant has 14 days to respond. If no confirmation is received within that time, the Home Office proceeds to consider the most recently submitted application on its own, treating the others as having been varied by it. If it remains unclear which application is the most recent, a different rule applies: all the submitted applications are treated as invalid.
If it remains unclear which application is the most recent, a different rule applies: all the submitted applications are treated as invalid.
If the Home Office cannot clearly identify the most recent application, it will request confirmation. You get 14 days to respond — without a reply, the department will pick the most recent application itself.
Frequently asked questions
Can I withdraw the first application myself so I don’t have to wait for the second one to replace it?
There’s no need to withdraw the first application separately: as soon as a second application is submitted before a decision on the first, Rule 34BB automatically makes only the newest one active, and the earlier one simply stops being considered, without a separate refusal decision.
Can I submit a third application if I’ve already submitted two?
Rule 34BB directly addresses submitting a new application before a decision on a previous one and requires that the most recent of the submitted applications be considered — so with a third application, that one becomes the active one, and the second stops being considered, just as the first did before it.
Can I submit a second application if I haven’t given biometrics for the first yet?
Technically you can, but it’s risky: until biometrics are given, Section 3C status on the first application isn’t activated, which means the transfer of rights to the new application works differently — it’s safer to give biometrics on the first application first and only then vary it.
