If you work in HR or run a business that sponsors overseas workers, Indefinite Leave to Remain (ILR) is a milestone you need to understand — not just for your employees' sake, but for your own compliance obligations.
Here's a practical breakdown of how ILR works, what it means for right to work checks, and how to keep your HR processes aligned with UK immigration law.
What ILR means for sponsored workers
When an employee holds a Skilled Worker visa, they're tied to their licensed sponsor. They can only work for you in the specific role you've sponsored them for. This changes fundamentally when they receive ILR.
Once an employee has ILR:
- They are no longer tied to their sponsor
- Their right to work becomes permanent and unrestricted
- You no longer need to track their visa expiry dates
- Your sponsor monitoring obligations for that individual end
This is a significant administrative shift. Build a system to flag when sponsored workers are approaching their ILR eligibility date — it's a positive transition for everyone.
The 5-year mark: what your HR system should track
Most Skilled Worker visa holders become eligible for ILR after 5 continuous years of residence. Here's a practical checklist:
Absences from the UK: Employees must not exceed 180 days absence in any rolling 12-month period. If a sponsored worker travels frequently for business, flag this early. Excess absences can reset their ILR eligibility clock.
Visa expiry date: The employee's visa must not expire before they apply. Applications should be submitted well before expiry.
Role and salary compliance: Throughout the 5-year period, the employee must have remained within their sponsor-approved occupation code and above the relevant salary threshold.
Sponsor licence status: If your licence is suspended or revoked before the employee reaches ILR eligibility, their visa could be curtailed — affecting their qualifying period.
Right to work implications
Under UK immigration legislation, employers must conduct right to work checks on all employees. For ILR holders, this changes as follows:
Before ILR: Check their Biometric Residence Permit (BRP) or eVisa profile, and re-check at the visa expiry date.
After ILR: The employee's right to work is indefinite. A single check is sufficient — no re-check required. This applies whether ILR is evidenced via a BRP card or through the Home Office online checking service.
One important note: physical BRP cards are being phased out. The UK has been transitioning to eVisas, meaning employees prove their ILR status through the UKVI online portal. Ensure your HR processes can handle digital right-to-work checks.
Sponsor licence duties during an ILR application
While a sponsored worker's ILR application is pending, they have "section 3C leave" — their existing visa conditions continue. This means:
- They can continue working for you under existing visa conditions
- You still have sponsor licence reporting duties
- Restrictions on their visa still apply until ILR is granted
HR teams sometimes assume that once someone applies for ILR, the sponsorship relationship ends. It doesn't — not until ILR is actually granted.
Building an ILR tracker
A simple tracking spreadsheet should cover:
| Field | Notes |
|---|---|
| Employee name | |
| Visa type | Skilled Worker, Dependent, etc. |
| Visa start date | |
| Visa expiry date | |
| Estimated ILR eligibility | Start + 5 years (adjusted for absences) |
| Total absences (rolling 12-month) | Flag if approaching 180 days |
| Life in the UK Test passed? | Required before application |
| English language evidence | Required before application |
| ILR application submitted | Date |
| ILR granted | Date |
Many HRMS platforms (Workday, BambooHR, Personio) lack built-in UK immigration tracking. A supplementary tracker in Excel, Notion, or a dedicated immigration management tool is usually needed.
After ILR: what changes for HR
Once ILR is granted:
- No more visa renewal reminders for that employee
- Right to work check is permanent — no re-check required
- No more sponsor licence reporting for that individual
- The employee is free to change roles or working patterns without immigration implications
From an HR admin perspective, ILR converts a high-maintenance employee record into a low-maintenance one.
The path to British citizenship
Most ILR holders become eligible for naturalisation after 12 months of continuous post-ILR residence. If an employee is married to a British citizen, they can apply for citizenship immediately after receiving ILR.
Worth knowing for retention conversations — many sponsored workers see ILR and eventual citizenship as long-term anchors to the UK.
Staying current on immigration rules
UK immigration rules change frequently. Salary thresholds shift, occupation code lists are updated, and policy changes can affect eligibility without much notice.
Tools like ImmigrationGPT can help HR teams quickly check current eligibility requirements, understand sponsor duties, and handle employee queries about their immigration status.
