Evidencing continuous lawful residence for 10-year ILR (with a visa-switch gap)
Your continuity almost certainly turns on lawful leave coverage and grant dates — not the exact day you submitted your 2017 ICT Long-Term application. For the 10-year long residence route, the Home Office assesses whether you held valid permission continuously, not whether you were physically present every day. A short gap during a visa switch, and a handful of days spent abroad while a new BRP was issued, are common and are dealt with under defined rules.
- You need 10 years' continuous and lawful residence in the UK.
- Continuity is about valid leave coverage, not unbroken physical presence.
- Absences after 11 April 2024: no more than 180 days in any rolling 12-month period.
- Absences before 11 April 2024: no more than 548 days total, and no single trip over 184 days.
- Core evidence: all passports held, BRP (can be expired) or eVisa, plus decision letters.
What "continuous lawful residence" actually means
The long residence route requires ten years of continuous, lawful residence built from any qualifying combination of UK permissions. The word that does the heavy lifting is lawful: the continuous residence caseworker guidance treats continuity as a question of whether you held valid permission throughout, with time spent under section 3C leave counted as lawful presence on the relevant route.
That framing matters for your case. Leaving the UK on 15 July 2017, then re-entering on 19 August 2017 after your ICT Long-Term BRP was issued on 9 August 2017, does not in itself break continuity — provided your leave coverage and the timing of your application fit the rules below.
How a gap during a visa switch is assessed
The guidance sets out when continuity survives a gap. For applications made after 24 November 2016, continuous residence is not broken where you made a successful application for entry clearance before your previous permission expired, or within 14 days of it expiring (this 14-day allowance does not apply to applications made under the Long Residence route itself). Crucially, any period spent without valid permission during such a grace window does not break continuity, but it also will not be counted as lawful presence towards the qualifying period.
So the real questions for your ICT Short-Term to ICT Long-Term switch are: was the Long-Term application made while you still had valid leave (or in time), and did it succeed? If yes, your 34 days outside the UK during the transition are an absence to be counted against the day limits — not a break in lawful residence.
A gap created by switching visas is precisely the kind of fact pattern where wording and dates decide outcomes. This article is general information, not legal advice. Before you submit, have a regulated immigration adviser (OISC-registered or a solicitor) check your exact leave coverage against your dates. A wrong assumption here is expensive to unwind.
Do absences of ~113 days cause a problem?
Unlikely, on the face of it. Because part of your qualifying period falls before 11 April 2024 and part after, two regimes apply. For time before that date, you must not exceed 548 days of absence in total and no single trip may exceed 184 days. For time after it, the test is no more than 180 days in any rolling 12-month period. Around 113 days spread across the period sits well inside both — but check that no single absence and no rolling 12-month window breaches the relevant cap. Our absence limits explainer walks through how the windows are counted.
Does the application submission date matter?
Generally, no — not the way the grant and coverage dates do. Continuity is built from periods of valid leave, which the Home Office can verify from its own systems. Your vignettes, BRP issue dates and eVisa establish the timeline; a precise submission date is rarely decisive. If you genuinely need it confirmed, a Subject Access Request to UK Visas and Immigration retrieves your borders, immigration and citizenship records, free of charge via an online form. It is a sensible safety net for a switch-gap, letting you reconcile your own records against the Home Office's before you apply.
The evidence you should hold
GOV.UK's documents-you-must-provide list is short but specific: a current passport or travel ID, all passports held during your time in the UK, and your BRP (which can be expired) or your eVisa accessed through a share code. Your decision letters and a clear travel history round out the package. The combination you already hold — passports with vignettes, BRP, eVisa and travel records — is the standard evidence set for exactly this route.
