The Global Business Mobility (GBM) Senior or Specialist Worker route is the UK’s primary sponsored route for intra-group assignments. It allows a multinational group to transfer a senior or specialist employee to the UK on a temporary work assignment, where the UK host entity is linked to the worker’s overseas employer, for example through common ownership or control, or through a qualifying joint venture arrangement.
This route replaced the former Intra-Company Transfer category and is designed for temporary business mobility rather than long-term migration. It does not lead to settlement (ILR), although some individuals may later be eligible to switch into a different immigration route.
To qualify under the GBM Senior or Specialist route, an applicant must meet the requirements set out in the immigration rules, which include:
English language is not a requirement under the Global Business Mobility – Senior or Specialist Worker route. Applicants are therefore not required to take an approved English language test or provide evidence of an English-language qualification as part of the application.
A key feature of the GBM Senior or Specialist Worker route is that it is intended for existing employees of a multinational group who are being assigned to the UK on a temporary basis. As a result, most applicants must meet the overseas work requirement.
In summary, the applicant must be currently working for the sponsor group on the date of application and, in most cases, must also show a qualifying period of overseas work for that sponsor group.
Where the standard requirement applies, the applicant must:
The “12 months working outside the UK” does not need to be continuous, as long as it is accumulated during the relevant period of continuous employment with the sponsor group.
High earners do not need to meet this requirement, as long as they can demonstrate that they are employed by the sponsor group on the date of the application.
A person who is already in the UK may be able to “switch” into the route (i.e. apply for permission to stay) rather than leaving the UK to apply for entry clearance. Whether switching is possible depends primarily on the applicant’s current immigration category and, where relevant, the additional rules for Students.
Switching into Skilled Worker is normally not permitted where the applicant was last granted permission:
In these scenarios, the applicant will generally need to leave the UK and apply for entry clearance as a Skilled Worker.
Even where switching is permitted in principle, applicants must still meet the Senior or Specialist Worker eligibility requirements, including the overseas work requirement, which means time spent working outside the UK during a period of continuous employment with the sponsor group. This can be a limiting factor for some in‑country switch applications and should be checked carefully before the Certificate of Sponsorship is assigned.
Applicants who have, or last had, permission as a Student can switch into Skilled Worker only if they meet one of the Student-specific conditions on the date of application. In broad terms, this requires that they have either:
If an application under the GBM Senior or Specialist Worker route is approved, permission is granted in line with the work dates on the Certificate of Sponsorship (CoS), subject to the route’s time limits.
In most cases, the Home Office will grant permission until the earliest of:
For most applicants, the maximum time permitted across the GBM routes is a cumulative total of 5 years in any 6-year period. Where the assignment qualifies as a high earner assignment (currently where gross annual salary is at least £73,900, assessed on the basis of a maximum 48-hour week), the cumulative limit is typically 9 years in any 10-year period.
A limited transitional arrangement applies to some long-standing intra-company assignees. Where an applicant is applying in-country and previously held permission under the Tier 2 (Intra-Company Transfer) rules in force before 6 April 2011 (or as a Work Permit holder under earlier rules) and has held continuous permission on the relevant successor route since, they may be exempt from the maximum cumulative limit and can be granted permission for up to 5 years at a time (subject to meeting the other route requirements).
The GBM Senior or Specialist Worker route is a temporary assignment route and does not lead directly to settlement (indefinite leave to remain). Time spent in the UK with permission under this route does not count towards the qualifying residence period for settlement.
Where long-term residence in the UK is an objective, it is usually necessary to plan an onward immigration strategy and, where permitted under the Immigration Rules, consider switching into a route that does lead to settlement (for example, a sponsored work route that can count towards ILR). Whether switching is possible, and when it is best done, will depend on the individual’s circumstances, the UK role, and the sponsor’s requirements.
The GBM Senior or Specialist Worker route is highly technical in practice. Successful applications usually depend on getting the fundamentals right at the outset, including the corporate link, overseas work requirement, role classification, salary structure (including permitted allowances), and the rules on third‑party working. Distinct Law supports both sponsors and assignees to ensure the application strategy is clear, compliant and aligned with business timelines.
Services typically include:
Yes. A GBM Senior or Specialist Worker can usually be accompanied or joined by a partner and dependent children, provided they meet the relevant dependant requirements. Dependants are granted permission in line with the main applicant’s permission and will need to make their own applications (and pay the relevant fees), with supporting evidence of the relationship and, where applicable, the financial position.
Yes, but only certain allowances can be counted, and the rules are more flexible than Skilled Worker in this respect. For GBM Senior or Specialist Workers, the Home Office can take account of guaranteed basic gross pay and certain guaranteed allowances that are payable for the duration of the UK employment, including allowances such as accommodation, London weighting or payments intended to reflect mobility or the additional cost of living in the UK. However, not all benefits count (for example, bonuses, overtime, employer pension contributions and most benefits-in-kind are generally excluded). Where an allowance relates solely to accommodation, only a capped amount can be counted towards the salary requirement, so the structure of the remuneration package should be checked carefully before the CoS is assigned.
In most cases, no. GBM Senior or Specialist Workers are normally restricted to working only for their sponsoring employer in the role described on the Certificate of Sponsorship, alongside permitted activities such as study and voluntary work. There is a limited transitional exception for some individuals who were previously granted permission under the GBM or legacy Intra-Company routes under rules in force before 11 April 2022 and have held continuous permission since, in which case supplementary employment may be permitted within strict limits. Where this is relevant, the individual’s immigration history and conditions should be checked before any additional work is undertaken.
Where an individual could qualify under either route, the choice usually depends on the commercial purpose of the assignment and whether the UK role is intended to be temporary or a longer-term hire.
GBM Senior or Specialist Worker is often preferred for intra-group assignments where the worker is being deployed to the UK as part of a wider corporate structure and the employer wants a route designed specifically for temporary mobility. A key advantage is that there is no English language requirement, which can make the process more straightforward for some assignees. The route is also structured around an intra-group transfer model and may align better with global mobility programmes, particularly where the worker remains part of an overseas employment framework and is assigned to the UK entity for a defined period.
However, the GBM route has significant limitations. It does not lead to settlement and time spent in the route does not count towards ILR, so it is generally not suitable where UK settlement is a medium-term objective. In addition, GBM Senior or Specialist Workers are normally restricted to working only for their sponsor in the sponsored role and cannot usually take supplementary employment (save for limited transitional cases linked to legacy Intra-Company visas). GBM routes are also subject to cumulative maximum stay limits, which can constrain repeat or long-term assignments.
By contrast, Skilled Worker typically suits long-term UK employment, includes a clearer route to settlement after the qualifying period, and allows limited supplementary employment within the Skilled Worker conditions. The most appropriate route therefore depends on factors such as the intended duration of UK presence, whether settlement is part of the individual’s objectives, and how the group intends to structure employment and mobility over time.
