Flagship counsel analysis · Current Rules and sponsor guidance checked 7 September 2026
Route selection should follow the UK business model, not the executive's preferred visa label.
The UK Expansion Worker route is available only before the overseas business begins trading in the UK. Once a UK operation is trading, the sponsor and worker must qualify under a route suited to the actual employment or assignment, commonly Senior or Specialist Worker or Skilled Worker.
The position
Which visa should a US company use when expanding to the UK?
A US company that has not yet begun trading in the UK may be able to use the UK Expansion Worker route to send senior managers or specialist employees to establish a qualifying UK branch or subsidiary. If the UK business is already trading, UK Expansion Worker is not the correct route; an eligible temporary intra-group assignment may use Senior or Specialist Worker, while genuine employment by the UK business may use Skilled Worker. UK Expansion Worker and the other Global Business Mobility routes are temporary and do not lead directly to settlement, whereas Skilled Worker can lead to settlement after the qualifying period. The route must be selected before the corporate structure, trading launch and worker assignment are finalised.
- The overseas business must establish the required ownership or control link and, for UK Expansion Worker, normally a qualifying overseas trading history.
- UK Expansion Worker requires genuine expansion work, not ordinary staffing of a UK business that is already trading.
- A UK company owned by the worker does not remove the genuine-role, salary, sponsor-governance or worker eligibility requirements for Skilled Worker.
A US business entering the UK often treats incorporation, immigration and hiring as separate workstreams. They are not. The legal entity that will trade, the entity that will employ or host the worker, the date UK trading begins and the intended duration of the assignment determine which sponsor licence and worker route can lawfully support the plan.
UK Expansion Worker can be effective where a mature US business is establishing its first UK trading presence and needs senior personnel to execute that expansion. It is not a general founder visa and it does not lead to settlement. If the UK entity has already begun trading, the route is ordinarily closed and the organisation must examine a different sponsor category.
Skilled Worker may be the better structure where the UK company will be the genuine employer and the role is intended to endure. Senior or Specialist Worker may suit a temporary intra-group assignment to an established UK entity. The decision cannot be made safely from salary or speed alone: control, trading status, overseas employment, ownership and long-term residence all matter.
01 · Operating model
Begin with what the US business will actually do in the UK.
The first schedule should identify the US parent, proposed UK branch or subsidiary, ownership chain, contracting entity, employing entity, premises, banking arrangements, anticipated customers and proposed trading date. It should then record who will work in the UK, who will direct them and whether their assignment is temporary or intended to become a permanent UK role.
Those facts separate the principal routes. UK Expansion Worker supports work required to establish a UK operation that has not begun trading. Senior or Specialist Worker supports a temporary assignment from a linked overseas business to an established UK sponsor. Skilled Worker supports employment in an eligible UK role by the licensed UK organisation. The immigration description must match the corporate evidence and the commercial reality.
02 · Before UK trading
UK Expansion Worker is a tightly defined pre-trading route.
Current sponsor guidance states that UK Expansion Worker can be used only where the overseas business has not yet begun trading in the UK. The applicant must be a senior manager or specialist employee undertaking work connected with the expansion. The UK operation must be linked to the overseas business by qualifying common ownership or control, and the overseas business must normally have traded overseas for at least 3 years.
The sponsor may use the route for the number of workers genuinely required to establish the UK business, subject to a maximum of 10 at any 1 time. Each role must meet the route's skill and salary requirements. From 8 April 2026, the general salary threshold is £52,500 or the applicable going rate if higher, subject to the complete current Rules.
Permission is initially available for up to 1 year and may be extended to a maximum continuous period of 2 years on the route. The Home Office expects the UK trading presence to be established within that period. Failure to do so can prevent further sponsorship and place the licence at risk.
03 · Trading status
The point at which UK trading begins is a route boundary, not an administrative detail.
Incorporating a company, obtaining premises or opening a bank account does not necessarily mean that UK trading has begun. Equally, a company can begin trading before it issues a first substantial invoice. Executed customer contracts, delivery of paid services, sales activity, payroll, VAT records and public statements may all be relevant to the factual assessment.
A business should not delay or artificially characterise genuine trading to preserve UK Expansion Worker eligibility. Nor should it launch trading without recognising that the route may then be unavailable. Corporate counsel, accountants and the immigration team should agree a documented launch sequence before the sponsor application is submitted.
Corporate act
Identify incorporation, registration, ownership and authority to operate.
Commercial act
Identify when the UK entity first supplies, sells or contracts in its own operating capacity.
Evidence
Reconcile contracts, invoices, bank activity, premises, payroll, tax and public statements.
Route consequence
Confirm whether the business is still pre-trading before relying on UK Expansion Worker.
04 · Established UK operation
Senior or Specialist Worker is for a temporary assignment within a qualifying group.
Where the UK business is already trading and is linked to the US business by common ownership or control, Senior or Specialist Worker may support the temporary assignment of a senior manager or specialist employee. The worker must already work for the sponsor group and will normally need the prescribed period of overseas service unless an exception applies.
The route requires eligible graduate-level work and, from 8 April 2026, ordinarily a salary of at least £52,500 or the specified going rate if higher. It does not lead to settlement. A business that describes a permanent UK appointment as a temporary assignment may create difficulty at application, compliance and extension stages.
05 · UK employment
Skilled Worker may fit a durable role employed and controlled in the UK.
Skilled Worker requires a licensed UK sponsor, a genuine eligible job, the applicable salary and going rate, and the worker's compliance with the route's personal requirements. The UK employer must accept substantive responsibility for the employment, reporting and sponsor duties. Ownership by the US parent or by the proposed worker does not disapply those tests.
Unlike Global Business Mobility, Skilled Worker can lead to settlement after the applicable 5-year qualifying period. That feature may be decisive for an executive relocating with a family. It should not, however, be used to disguise an assignment in which the US business remains the true employer and the UK company has little operating substance or control.
06 · The individual
Overseas service, English language and settlement intention can change the answer.
Global Business Mobility applicants must be existing employees of the relevant overseas business or sponsor group and normally satisfy an overseas work requirement. The UK Expansion Worker and Senior or Specialist Worker exceptions for high earners are defined by the current guidance; a senior title alone is insufficient.
Skilled Worker does not impose the same intra-group overseas service condition, but it ordinarily requires English language and a role that meets the current occupation and salary framework. The individual's UK immigration history, proposed start date, dependant position and intended settlement path should be modelled before the employer selects the apparent fastest route.
07 · Sponsor architecture
The sponsor licence must sit with the organisation that can perform the duties.
UK Expansion Worker has a special provisional-rating structure where the Authorising Officer is based overseas and will assign a Certificate of Sponsorship to themselves. The licence can move to an A-rating after an eligible UK-based Authorising Officer is appointed and the required steps are completed. That sequence should be built into the expansion plan rather than treated as an afterthought.
For an established UK operation, the licence holder must control the sponsored employment, maintain the required records, monitor attendance and changes, and report specified events. Group-wide human resources systems can assist, but the licensed entity remains accountable for its own compliance.
08 · Counsel judgment
A route comparison should include the failure scenario as well as the intended launch.
A plan may begin while the UK entity is pre-trading but reach filing after a customer contract has gone live. An executive expected to remain for 12 months may later become central to the UK operation. A temporary route can then create an avoidable second application, while a premature Skilled Worker structure can expose weak UK employment and governance.
The advice should state the selected route, the facts on which that selection depends, the evidence still required and the event that would trigger reconsideration. This makes immigration part of the transaction plan and protects the business from relying on a route whose factual basis has disappeared.
Decision framework
Select the route through 6 connected decisions.
The route should be fixed only after the UK operation and the individual's assignment have been tested against the same evidence.
Map the entities
Record ownership, control, contracting, employment and the proposed UK establishment.
Fix the trading status
Determine whether UK trading has begun and identify the evidence supporting that conclusion.
Define the assignment
Set duties, occupation code, salary, work location, reporting line and expected duration.
Test the individual
Check overseas service, English language, immigration history, family position and settlement objective.
Build sponsor governance
Appoint eligible key personnel and establish control, record keeping, monitoring and reporting.
Plan the transition
Identify what happens when UK trading starts, the assignment changes or longer-term residence becomes necessary.
Practical questions.
Can a US company use UK Expansion Worker after its UK subsidiary starts trading?
Ordinarily no. Current sponsor guidance states that UK Expansion Worker is available only where the business has not begun trading in the UK. An already trading operation should consider another route, commonly Senior or Specialist Worker or Skilled Worker, according to the actual assignment and employment.
Does UK Expansion Worker lead to indefinite leave to remain?
No. UK Expansion Worker and the other Global Business Mobility routes do not lead directly to settlement. Skilled Worker can lead to settlement after the applicable qualifying period if all requirements are met.
How many UK Expansion Workers can a business sponsor?
The current guidance permits only the number genuinely required to establish the UK business, up to a maximum of 10 workers at any 1 time. The sponsor must justify each role rather than treating 10 as an automatic allocation.
Can the US founder use Skilled Worker through the UK subsidiary?
Potentially, but there is no separate self-sponsorship route. The UK company must be a genuine licensed sponsor, the role must be real and eligible, salary and worker requirements must be met, and sponsor governance must be credible despite the founder's ownership.
Is Senior or Specialist Worker better than Skilled Worker for an intra-group transfer?
It depends on the facts. Senior or Specialist Worker reflects a temporary qualifying group assignment and does not lead to settlement. Skilled Worker may fit genuine UK employment and can lead to settlement, but it carries different worker, role and sponsor requirements.
When should the immigration structure be decided?
Before UK trading, employment documents and the executive's move are irrevocably fixed. The route can be lost or undermined if the business launches first and attempts to reconstruct the evidence afterwards.
