Does the 10-year UK Indefinite Leave to Remain route count as overstaying? How is the waiting time for a decision calculated?

Paragraph 11.2 of Appendix LR on Long Residence in the current Immigration Rules states: "The following periods will not count towards the qualifying period for Long Residence:" (i.e., the following periods will not count towards the qualifying period for long residence), and the listed items include periods without leave that fall under the overstaying exceptions.

If you previously submitted a late application for an extension and it was subsequently approved, this rule will still affect the completion date for the 10-year Long Residence. When calculating the period, it is essential to determine the length of the period without leave and whether this gap can qualify for the continuous residence exception.

Can the period of overstay still be counted towards the 10-year permanent residency?

Ordinary overstay cannot be counted. Appendix LR 11.1 on Long Residence requires ten years of lawful residence; LR 11.2(b) to (d) list historical overstay and current overstay subject to exceptions as periods that do not count. "Disregarded" means that qualifying overstay does not break continuous residence, nor does it add to the accumulable period. The corresponding provisions in the Immigration Rules, Appendix Continuous Residence CR 4.1(d)(i) and CR 4.2, must be read together: the former sets out the linking conditions, while the latter excludes days without leave. There are also specific arrangements for the pandemic period, which are detailed separately below.

Therefore, even if the calendar time spent living in the UK reaches ten years, it may still fall short of ten years of qualifying time.

Only 10 days late on the payment, why deduct more than half a year?

The "Continuous residence" guidance updated by Home Office on 8 October 2026 provides an official calculation example in the "Overstaying exceptions" section: the applicant originally held three years of leave and submitted a late application ten days after its expiry; the late submission was due to a good reason beyond the applicant's control, thus meeting the overstaying exception; the application took six months to process, after which a new three-year leave was granted. Once both periods of leave are fully utilized, the total accumulated period is six years. The ten days plus six months in between do not break continuity, yet this entire intervening period is not counted towards the qualifying period. The period excluded extends up to the grant of the new leave; it is not limited to just the ten days prior to the late submission. This is also why, when reviewing old records, both the approval notice and the submission receipt must be retrieved together.

My judgment is that for those confirmed to be eligible for the overstay exception, the entire period of unauthorized stay must be deducted from the priority date; merely pushing back the filing date by the few days of late submission is insufficient.

The waiting period for applications submitted on time must be calculated separately. Pursuant to Section 3C of the Immigration Act 1971 and the accompanying guidance Home Office, where a valid application for extension or variation is made in-country while the applicant holds valid leave, and the original leave expires while the application remains pending, the leave is extended by operation of law provided the conditions are met. Where the original leave falls within a countable category, this extended period may be counted. An ordinary late application does not have the same automatic extension effect; furthermore, subsequent approval alone cannot retrospectively validate the waiting period as lawful residence. Even if two case files both state "awaiting decision for six months," the calculation outcomes may still differ.

Can the front and back sections still be joined together?

Whether continuity can be established between the preceding and subsequent periods, and the identification of applicable exception clauses, cannot be fully assessed based solely on the outcome of a previous renewal.

For subsequently approved late in-country applications, CR 4.1(d)(i) requires compliance with the out-of-time exception under Part Suitability. The commonly invoked SUI 13.1(a) involves making an application within 14 days of the expiry of the original leave, accompanied by a statement of sufficient reasons beyond the control of the applicant or their representative that prevented timely submission, subject to acceptance at the discretion of the decision maker. Individuals who previously made a timely application and subsequently underwent refusal or other proceedings may also be subject to a separate set of conditions under SUI 13.1(b), necessitating a review of the complete procedural record. For earlier historical gaps, separate provisions apply: CR 4.1(d)(iv) sets out conditions such as submission within 28 days of expiry and successful approval for periods without leave prior to November 24, 2016. Legacy files must be assessed against the corresponding dates, and a set number of days cannot serve as a blanket guarantee.

Where exceptions apply, continuity can still be maintained after deducting the gap period; however, any overstay not covered by an applicable exception will break continuous residence, and this cannot be remedied simply by staying an additional equivalent number of days.

Should the entire gap during the pandemic be deducted as well?

Pandemic records must distinguish between policy names. The Coronavirus Extension Concession from 24 January to 31 July 2020 extended leave for eligible individuals; the subsequent grace period from 1 to 31 August 2020 allowed time meeting the requirements of CR 4.1(d)(v) to be recognized as lawful time in the UK under CR 4.3 and counted accordingly. Conditions include having held leave immediately prior to this period without leave. The entire pandemic period cannot be added to the qualifying period simply because the individual was physically present in the UK at the time; when making enquiries, the original leave expiry date must be matched with the relevant policy coverage period.

Exceptional Assurance granted between 1 September 2020 and 28 February 2023 will not count towards the qualifying period for indefinite leave to remain.

The pandemic-specific guidelines of Home Office clearly state that the special assurance of protection for a specified period does not, in itself, confer a residence permit. Periods covered by this arrangement may not break the continuity of residence, but must still be deducted from the accumulable time. Whether the retained document is a notice of extension of leave or a notice of special assurance will affect the calculation outcome; when compiling the records, the complete notice, the approved start and end dates, and the preceding and subsequent leave records must be retained. Flight cancellation documents alone cannot substitute for verifying which specific arrangement actually applies to the individual, nor can a single notice be used to cover other months that were not approved.

Incomplete Previous UK Visa Records: Where to Start Looking?

I suggest creating a timeline that lists each blank period separately, retaining the file names and application numbers for easy future reference.

The timeline must include at least the expiry date of the original leave, the date the valid application was submitted, the effective date of the new leave, and whether any Section 3C extension applies in the interim. Subsequently, attach the submission receipt, decision letter, and documents explaining the reasons for late submission to the corresponding milestones; if there has been a refusal, a review, or a withdrawal of the decision, the relevant notifications must also be included. For each period without leave, clearly specify "the number of days excluded" and "the provision under which continuity can still be maintained." This is the methodology for organizing the information; a legal determination cannot be made merely by entering an exception number into a table. When the decision letter does not explicitly state how the overstay is to be handled, the complete application and processing records for that year must be verified to avoid presenting speculation as a confirmed conclusion.

The handling of overdue old cases is also subject to formal verification requirements.

The "How to identify overstaying" section of the "Continuous residence" guidance requires caseworkers to review historical cases to confirm whether overstaying was previously treated as an exception. If documents are missing, a Subject Access Request can be submitted to Home Office to obtain the application and decision dates, specific decision letters, or relevant files, specifying the scope of the records required. The official guidance on personal data access permits such requests. Once the records are obtained, eligibility must still be assessed independently or by a professional; the information retrieved is used to reconstruct the timeline and does not directly conclude that one is eligible to apply for indefinite leave to remain.

After the calculation, also verify whether the new expiration date falls within the current license validity period. If the license expires first, renewal arrangements must be evaluated separately; you cannot simply add days to the countdown.
