Section 3C leave rule changes take effect on 8 October 2026
From 8 October 2026 new immigration rules require biometrics for variation applications and tighten fee‑waiver timing, altering how Section 3C leave is triggered and maintained for migrants with pending applications. The changes apply to anyone whose leave is extended under Section 3C of the Immigration Act 1971.

The details
- Announced by
- Home Office
- Takes effect
- 8 October 2026
- Previous rule
- Previously, a variation application could be valid without enrolling biometrics if the enrolment deadline was met before the variation was submitted.
- New rule
- From 8 October 2026, any variation application must still meet the biometrics deadline of the original application, and fee‑waiver requests must be followed by an application on the same route within ten working days.
What is Section 3C leave
Section 3C leave automatically extends a migrant’s permission when a valid immigration application is made before the current leave expires and no decision is made by the expiry date. The extension lasts until a decision is reached, an appeal period ends, or the applicant leaves the UK.
Rule amendments effective 8 October 2026
Two amendments to the immigration rules were introduced on 8 October 2026. The first inserts sub‑paragraph 2A into paragraph 34BB, stating that a variation application must still comply with the biometrics deadline of the original application. The second revises paragraph 34G(4) to require that a fee‑waiver request be followed by an application on the same route within ten working days, even if the waiver is refused.
- Biometrics deadline remains unchanged for variation applications
- Fee‑waiver request must be matched by a same‑route application within ten working days
Practical impact of the changes
The amendments mean that applicants cannot rely on a variation to bypass biometrics requirements, and they must ensure the post‑waiver application matches the original route to retain Section 3C protection. Failure to meet these conditions will cause Section 3C leave to lapse, potentially creating a period without lawful permission.
- If biometrics are not submitted on time, the application becomes invalid and Section 3C leave ends
- Submitting a different route after a fee‑waiver request breaks the Section 3C continuity
What this means for travellers
Trip planning
- Existing bookings remain valid; however, travelers must ensure any pending application complies with the new biometrics deadline to avoid loss of leave while abroad
- Leaving the UK (including Ireland, Isle of Man or Channel Islands) will still cause Section 3C leave to lapse under existing rules
Cost and documents
- No new fees are introduced; the cost of biometrics enrolment remains as previously required
- Applicants must retain proof of biometrics submission and the date of any fee‑waiver request for the ten‑day window
What you need to do
- Check that any variation application submitted after 8 October 2026 includes biometrics that meet the original deadline
- If a fee‑waiver was requested, submit the subsequent application on the same route within ten working days
- Monitor the Home Office decision timeline to ensure Section 3C leave does not expire before a decision or appeal is resolved
Who this affects
-
Applicants with pending extension or variation applications
Section 3C leave is triggered when a valid application is made before current leave expires and no decision is made by the expiry date.
What to do Ensure biometrics are submitted by the original deadline and avoid varying the application after the deadline.
-
Fee‑waiver requesters
The new rule ties the date of the fee‑waiver request to the subsequent application only if it is on the same route and filed within ten working days.
What to do File the follow‑up application on the same route within the ten‑day window to preserve Section 3C protection.
-
Travelers leaving the Common Travel Area while on Section 3C leave
Paragraph 34K treats a pending application as withdrawn when the person leaves the CTA, causing Section 3C leave to lapse.
What to do Avoid travel to Ireland, the Isle of Man or the Channel Islands until a Home Office decision is received.
Frequently asked questions
When does Section 3C leave start?
Section 3C leave begins on the date the original permission would have expired if the Home Office has not yet decided on a valid application made before that expiry.
Do I still need to provide biometrics for a variation application after 8 October 2026?
Yes, the new rule requires that the biometrics deadline of the original application still be met for any variation submitted after 8 October 2026.
What happens if I request a fee waiver but submit a different type of application?
The fee‑waiver date will not count for Section 3C purposes unless the subsequent application is for the same route and filed within ten working days of the waiver decision.
Will Section 3C leave continue while I appeal a refusal?
Section 3C leave remains in force during the appeal period, provided the appeal is lodged within the 14‑day deadline after the refusal.
Can I travel to Ireland while on Section 3C leave?
No, leaving the Common Travel Area, which includes Ireland, the Isle of Man and the Channel Islands, will cause Section 3C leave to lapse even if the application is still pending.
