GBM and ILR: Why Most Global Business Mobility Workers Cannot Settle and What Their Options Are

Written by Bill Zahr

Last Updated 09 June 2026

Executive summary

The Global Business Mobility framework provides five routes for deploying overseas workers to the UK. None of these routes lead to Indefinite Leave to Remain. The GBM framework was designed as a short-to-medium term deployment mechanism — not a settlement pathway.

This has significant consequences for multinationals that deploy senior talent to the UK on long-term assignments, and for the workers themselves. This article addresses the ILR gap in the GBM framework and sets out the strategic options for Global Mobility Directors and HR planning teams.

The ILR Gap: What Most HR Teams Do Not Know

The GBM framework was designed in 2022 primarily as a mechanism for short-to-medium term intra-corporate deployments. It was not designed as a settlement pathway. The Home Office's policy intention is clear: GBM workers are expected to return to their home country or overseas group entity at the end of their assignment, not to settle permanently in the UK.

In practice, however, many of the workers deployed under GBM routes particularly under the Senior or Specialist Worker route are highly talented individuals whom UK entities wish to retain on a permanent basis. The mismatch between the commercial desire for retention and the immigration framework's settlement limitations is one of the most persistent challenges in corporate immigration planning.

Which GBM Routes Lead to ILR and Which Do Not

GBM routes — ILR eligibility at a glance

GBM route ILR eligible? Max stay Settlement route
Senior or Specialist Worker ✗ No Up to 9 years Switch to Skilled Worker
Graduate Trainee ✗ No 12 months Switch to Skilled Worker
UK Expansion Worker ✗ No 2 years Switch to Skilled Worker
Secondment Worker ✗ No 2 years Switch to Skilled Worker
Service Supplier ✗ No 12 months (varies) Switch to Skilled Worker

⚠ None of the five GBM routes lead to ILR. Workers who wish to settle permanently in the UK must switch to the Skilled Worker route and complete 5 years of continuous qualifying residence under that route.

Senior or Specialist Worker Visa: Maximum Stay, Salary Thresholds and the Path to a Skilled Worker Switch

The Senior or Specialist Worker route is the most strategically significant of the five GBM sub-routes for long-term deployments. It does not lead to ILR, no GBM route does, but it provides a maximum stay of up to nine years for High Earners, making it the strongest platform within the GBM framework from which to plan a transition to the Skilled Worker route and ultimately to settlement.

The 9-Year Maximum Stay and the Rolling Clock

The nine-year maximum applies to High Earners, those paid £73,900 or above, and is calculated on a rolling basis across all time spent in the UK on the Senior or Specialist Worker route. Standard workers face a shorter maximum continuous stay. Time spent across multiple visa grants under this route counts cumulatively. An organisation that deploys a worker on this route without a Skilled Worker transition plan risks that worker reaching the maximum stay limit with no lawful basis to remain.

Salary Thresholds for the Senior or Specialist Worker Route

As of 2026, the salary threshold for the Senior or Specialist Worker route is £52,500 for standard workers and £73,900 for the High Earner category. These thresholds must be met throughout the deployment, not only at the point of application.

Planning the Switch to the Skilled Worker Route

Because the Senior or Specialist Worker route provides the longest GBM stay, it gives organisations the most time to plan and execute a switch to the Skilled Worker route. That switch requires a new Certificate of Sponsorship, an English language qualification at B2 level, and a salary meeting the Skilled Worker threshold. It should be planned from the start of the GBM deployment not when the maximum stay is approaching.

The 9-Year Maximum Stay and the Rolling Clock

The Senior or Specialist Worker visa has a maximum continuous stay in the UK of 5 years for standard workers and up to 9 years for High Earners. The 9-year period is calculated on a rolling basis: time spent in the UK on the Senior or Specialist Worker route across multiple visa grants counts cumulatively toward the maximum.

Critically, this rolling maximum is reset by periods spent outside the UK. Specifically, a worker who spends more than 12 months outside the UK (whether in a single continuous absence or in aggregate over a 24-month period) resets their rolling clock. This provision was designed to prevent the route from being used as a de facto permanent work permit by workers who spend most of their time outside the UK but dip in and out.

Planning the Switch to a Skilled Worker Visa for Long-Term Assignees

For workers on GBM routes that do not lead to ILR, or for Senior or Specialist Workers who wish to remain in the UK beyond the maximum GBM stay, switching to a Skilled Worker visa is the most common long-term pathway.

What the Switch Requires

A switch from a GBM route to the Skilled Worker route requires: a UK employer holding a valid Skilled Worker sponsor licence; a Certificate of Sponsorship issued for a specific role meeting the Skilled Worker salary and SOC code requirements; and, from January 2026, an English language test result at B2 CEFR level.

The English Language Planning Issue

The B2 English language requirement introduced in January 2026 is a significant planning consideration for GBM-to-Skilled Worker transitions. Workers who are planning a future Skilled Worker switch should obtain a B2 SELT result before the transition point, not at the point of application, by which time there may be insufficient time for testing if the result is not immediately achievable.

Workforce Planning Checklist for Global Mobility Directors

Workforce planning checklist for Global Mobility Directors

1
Understand that no GBM route leads to ILR. Any long-term assignee who wishes to settle permanently in the UK must plan a transition to the Skilled Worker route from the outset of the deployment.
2
Identify all workers approaching their GBM maximum stay limit and plan the transition to the Skilled Worker route at least 6 months before the GBM visa expires.
3
Review whether the UK entity's sponsor licence covers the Skilled Worker route in addition to the GBM A rating. A separate Skilled Worker authorisation is required to sponsor workers on the Skilled Worker route.
4
Assess English language readiness for Skilled Worker transitions. The B2 English language requirement introduced in January 2026 must be met at the point of the Skilled Worker application. Workers should obtain a qualifying SELT result well before the transition point.
5
Consider Global Talent visa eligibility for workers in academia, research, arts, culture, or digital technology as an alternative settlement pathway that does not require a sponsor licence.
6
Track 180-day absence limits for all workers from the start of their deployment. Absences affect both GBM maximum stay calculations and future Skilled Worker ILR eligibility.
7
Never assume a GBM worker can remain in the UK indefinitely. Every GBM visa has a maximum stay after which the worker must either have switched to an alternative route or left the UK. Allowing a GBM maximum stay to expire without a transition plan in place is a compliance failure.

ⓘ The most effective GBM strategy treats the Skilled Worker route as the default long-term pathway from day one of any deployment where settlement may ultimately be the objective.

Frequently Asked Questions

Can time spent on a Graduate Trainee visa count toward ILR?

No. Time spent on the Graduate Trainee route does not count toward ILR under any route. The Graduate Trainee visa is explicitly settlement-ineligible and time on this route is not aggregated with time on other routes for ILR purposes.

What is the Global Talent visa and could it provide a settlement pathway?

The Global Talent visa is available to individuals who are recognised leaders or emerging leaders in academia, research, arts, culture, or digital technology. Unlike the GBM framework, none of whose routes lead to ILR, the Global Talent visa does lead to settlement: after 3 years for Top Talent endorsees and 5 years for Promising Talent endorsees. It does not require a sponsor licence. For workers in eligible fields it is the most direct route to ILR available outside the Skilled Worker route, and should be considered as part of long-term workforce planning for qualifying individuals. Endorsement from a designated body is required before the visa can be applied for.

If a worker switches from Senior or Specialist Worker to Skilled Worker, does the GBM time count toward ILR?

No. Time spent on any GBM route, including the Senior or Specialist Worker route, does not count toward ILR. The five-year qualifying period for Skilled Worker ILR begins from the date the Skilled Worker visa is granted. There is no carry-over or aggregation of GBM time. The one exception worth noting is the long residence route: an individual who has been lawfully present in the UK for 10 continuous years under any combination of routes may apply for ILR on that basis, but this is a separate legal route with its own requirements, not an extension of GBM time.
