When you want to work in the UK, choosing the right visa route is important. The Skilled Worker visa suits those with a job offer in the UK, offering wider options across many sectors. The Senior or Specialist Worker visa is mainly for transferring senior staff or specialists within a company and usually comes with higher salary requirements and no English language test.
The Expansion Worker visa is designed for companies setting up new UK operations, allowing staff to move over temporarily to establish the business. The key difference is that Skilled Worker visas lead to settlement rights, while Senior or Specialist and Expansion Worker visas are mostly for temporary stays and internal transfers.
Understanding these visa types will help you match your situation with the right option, making your UK work plans smoother. Knowing the rules on sponsorship, salary, and eligibility will save you time and avoid mistakes.
Understanding UK Work Routes

You need to know how each work route fits your situation and what the main requirements are. This helps you choose the best option for working in the UK as an overseas worker. The right route depends on your job type, sponsorship, and mobility needs.
Overview of Available Work Routes
The main UK work routes include the Skilled Worker visa, Senior or Specialist Worker visa, and Expansion Worker route. The Skilled Worker visa is common for long-term skilled jobs and can lead to settlement. It requires meeting English language skills and job eligibility criteria.
The Senior or Specialist Worker visa is for jobs needing specialist abilities or senior roles. It does not require English language skills and is part of the Global Business Mobility (GBM) umbrella. The Expansion Worker route allows overseas companies to bring senior managers or specialists to set up or run a UK branch.
Each route has specific rules on job roles, length of stay, and sponsorship needs. Selecting the right one means considering your skills, employer, and future plans.
Role of the Sponsor Licence
To employ overseas workers under these routes, your UK employer must hold a sponsor licence. This licence allows them to sponsor migrant workers legally. It shows the business meets Home Office standards for recruiting abroad.
There are different types of licences depending on job types, including Skilled Worker and GBM sponsorship licences. The sponsor must keep records and report changes to the authorities, ensuring compliance.
Without a sponsor licence, you cannot get a Skilled Worker or many GBM visas. Your employer’s licence status directly impacts your application’s success and your ability to work legally in the UK.
Global Business Mobility Visa Explained
The Global Business Mobility (GBM) visa covers routes like the Senior or Specialist Worker and Expansion Worker visas. It is designed for overseas businesses sending employees to the UK temporarily or long term.
GBM visas do not always require you to prove English language skills. They focus on your role in the company, such as senior managers or specialists with key knowledge.
This route suits multi-national companies expanding or moving workers between global offices. It allows you to work in the UK without switching to a Skilled Worker visa, giving more flexibility for business needs.
Skilled Worker Visa Route
The Skilled Worker visa route allows you to work in the UK if you have a job offer from an approved sponsor. It is designed for professionals in eligible roles who meet specific skill and salary levels.
Eligibility Criteria for Skilled Worker Visa
To qualify, your job must be on the UK’s list of eligible occupations. You need a confirmed job offer from a UK employer holding a valid sponsor licence.
Your job must meet the minimum skill level, usually RQF Level 3 (A-level equivalent) or above. You also must earn at least the minimum salary threshold, which varies depending on the role.
You need to prove your knowledge of English to a required standard unless exempt. Your application depends on meeting these points-based criteria.
Sponsorship and Application Process
Your UK employer must have a sponsor licence to legally sponsor your visa. They issue a Certificate of Sponsorship (CoS) that is necessary for your application.
Once you receive the CoS, you apply online, submitting proof of your identity, job details, salary, and English skills. Fees and the healthcare surcharge must also be paid.
The visa allows you to work only for the sponsoring employer in the role stated. Any significant changes to your job may require a new visa application.
Benefits and Limitations of the Skilled Worker Route
This visa can lead to settlement (Indefinite Leave to Remain) after five years of continuous residence. You can bring dependants with you under this route.
It offers work rights with fewer restrictions compared to other UK work visas. You can switch jobs within the Skilled Worker category by getting a new sponsor licence from a different employer.
A key limitation is the strict requirements for skill level, salary, and English language. If you don’t meet these standards, you cannot apply under this route.
Senior or Specialist Worker Visa Route
This visa route is designed for overseas workers transferring to a UK branch of their employer. It provides options for senior managers, specialists, and graduate trainees to work temporarily in the UK, with specific eligibility rules and features that differ from other work visas.
Eligibility Criteria for Senior or Specialist Worker Visa
To qualify, you must currently work for an overseas branch of a company that also operates in the UK. Your role should fit one of these categories: senior manager, specialist employee, or graduate trainee. You need a valid sponsorship from your UK employer’s branch.
There is no English language test requirement for this visa. However, your employer must show your role meets the specific job criteria set for this route. Your role should be temporary, usually up to 12 or 24 months, depending on your job category.
Key Features and Distinctions
The Senior or Specialist Worker Visa is part of the Global Business Mobility (GBM) framework. It allows you to work in the UK without meeting the usual Skilled Worker Visa’s English language rule or salary threshold.
This visa permits shorter-term transfers. Unlike the Skilled Worker Visa, it does not lead directly to indefinite leave to remain (settlement) in most cases. Your sponsorship licence specifically covers this route, so your employer must hold a GBM licence.
Pathways for Intra-Company Transfers
This route supports temporary UK work for overseas employees who are transferred within their company. You can move to the UK branch as a senior manager or specialist, or join as a graduate trainee gaining UK experience.
The visa period varies: senior managers may stay longer (up to 24 months) while other workers usually have a shorter stay (up to 12 months). Extensions might be limited or not allowed, depending on your role.
You must maintain your employment with the overseas employer sponsoring your transfer throughout your visa. This visa is best suited for temporary assignments rather than long-term settlement.
UK Expansion Worker Visa Route
The UK Expansion Worker visa lets companies send senior staff to the UK to set up a new branch or subsidiary. This route helps you work legally in the UK if your employer wants to grow their business there. To use this visa, your company must hold the correct sponsor licence and follow specific rules.
Who Qualifies for the UK Expansion Worker Visa
You qualify if you are a senior employee within a company that does not yet have a UK branch or subsidiary. Your employer must be an overseas business expanding into the UK for the first time.
You must have worked for your employer continuously overseas for at least 12 months before your application. The visa targets senior-level staff like directors or managers essential for establishing the new UK operation.
The role you will do in the UK must be genuine and relate directly to setting up or running the new branch or subsidiary. You cannot use this visa for general job roles or companies with existing UK operations.
Requirements and Process for Expansion Workers
Your company must have a valid sponsor licence approved by UK Visas and Immigration. This licence permits them to sponsor you under the Expansion Worker category.
You need a Certificate of Sponsorship from your employer. This certificate confirms your role meets visa requirements, including salary thresholds and job duties.
You don’t have to meet an English language requirement, unlike some other UK work visas. You must, however, show proof of funds or meet specific maintenance rules.
You apply online, providing documents about your job, your company’s sponsor licence, and evidence of your overseas employment. The visa usually lasts for up to 12 months and can be extended.
Differences from Other Mobility Routes
Unlike the Skilled Worker visa, the Expansion Worker visa does not require job suitability tests like the Resident Labour Market Test.
The visa is for businesses expanding into the UK for the first time. This contrasts with the Senior or Specialist Worker visa, which is for transfers within established UK branches.
The Expansion Worker visa does not require an English language test but is more restrictive on the types of jobs allowed. Its main focus is on senior employees setting up UK businesses, not broader recruitment.
In summary, your employer’s overseas company status and your senior role in setting up UK operations make this visa unique compared to other work routes.
Comparing Work Routes: Choosing the Right Option
When deciding on a UK work visa, you must understand the key distinctions between options, your personal and job needs, and how each route fits your future plans. Other visa types may also apply depending on your role or transfer type. This section breaks down what matters most in choosing between Skilled Worker, Senior or Specialist Worker, and Expansion Worker visas.
Key Differences Between Work Visas
The Skilled Worker visa allows you to work in a wide range of skilled jobs across many industries. It requires a job offer from a UK-licensed sponsor, a minimum salary threshold, and proof of English language ability.
The Senior or Specialist Worker visa mainly serves to transfer senior managers or specialists within a company to a UK branch. It also needs sponsorship but has no English language requirement. This visa is more limited in scope compared to the Skilled Worker route.
The UK Expansion Worker visa is for businesses expanding into the UK without an existing branch. It lets you set up new operations and transfer overseas staff temporarily but does not lead directly to settlement.
Visa Type | Sponsorship Needed | English Requirement | Main Purpose | Settlement Route |
Skilled Worker | Yes | Yes | Skilled employment in the UK | Yes |
Senior or Specialist | Yes | No | Intra-company transfer of senior/specialist staff | Yes |
Expansion Worker | Yes | Not specified | Setting up a new UK business | No |
Factors to Consider When Selecting a Route
When choosing your visa, consider your job role, English language ability, and whether the sponsor meets UK requirements. Skilled Worker visas have wider job eligibility but require English skills and higher salary levels.
If you work in senior management or have specialist skills, and transferring within the same company, the Senior or Specialist Worker visa is often simpler due to no English test. However, this visa is limited to staff transfers and not open recruitment.
The Expansion Worker visa suits you if your employer is new to the UK. But it only allows temporary stay and no permanent settlement. Your length of stay and career goals should guide your choice.
Switching Between Routes and Long-Term Prospects
You can switch from a Senior or Specialist Worker visa to a Skilled Worker visa if you meet the requirements. This can improve your options, including the ability to apply for settlement after five years.
Expansion Workers cannot switch directly to Skilled Worker visas without leaving the UK first. Also, Expansion Worker visas do not lead to settlement, so if you want to stay long term, you’ll need a different route eventually.
Understanding each visa’s rules on switching is key to planning your career in the UK. The Skilled Worker visa offers the most direct path to permanent residence.
Alternatives: Graduate Trainee, Secondment, and Service Supplier Visas
If you are a recent graduate, the Graduate Trainee visa can be suitable. It allows temporary transfer to the UK for training purposes within the same company but is time-limited.
The Secondment Worker visa is for overseas workers seconded to a UK branch for a defined period, useful for short-term assignments.
The International Agreement route covers roles like diplomats or service suppliers working on contracts between countries or companies.
Each of these alternatives has specific sponsor and eligibility rules and generally does not lead to settlement. They are focused on temporary or specialised transfers rather than permanent employment.
