Expert legal advice for UK businesses on sponsor licences, overseas recruitment, Certificates of Sponsorship, sponsor compliance, Home Office audits, right to work checks, civil penalties and Global Business Mobility.
Recruiting international workers can help UK businesses access specialist skills, expand internationally and fill important roles, but sponsorship brings significant immigration and compliance responsibilities.
For many employers, the process begins with obtaining a Home Office sponsor licence.
A sponsor licence can allow an eligible UK organisation to sponsor overseas workers under routes such as the Skilled Worker Visa, certain Global Business Mobility routes and other sponsored work categories. Most employers wishing to recruit workers who do not already have permission to work in the UK will need the appropriate sponsor licence.
However, obtaining a licence is only the beginning.
Licensed sponsors must continue to comply with Home Office requirements throughout the life of the licence. This includes maintaining appropriate HR systems, monitoring sponsored workers, keeping required records, carrying out right to work checks and reporting relevant changes to UK Visas and Immigration.
Failures can result in serious consequences, including:

A UK employer will usually need a sponsor licence where it wants to employ someone who requires employer sponsorship to work in the UK.
This can include workers recruited from overseas.
However, not every overseas national requires sponsorship.
For example, a sponsor licence may not be necessary where an individual already has sufficient permission to work through a status such as:
The first question should therefore be:
Does the worker actually need sponsorship?
Where sponsorship is required, the employer must hold the correct licence for the immigration route concerned.
A sponsor licence is not automatically granted simply because a company is genuine and trading.
The Home Office will consider whether the organisation is eligible and capable of carrying out its sponsorship responsibilities.
Relevant issues can include:
UKVI reviews the application form and supporting documentation and may visit the business to assess whether it is trustworthy and capable of performing its sponsor duties.
This is why sponsor licence preparation should involve more than simply completing an online form.
When applying for and managing a sponsor licence, an organisation must appoint appropriate key personnel.
The principal sponsorship roles are:
A senior and competent person responsible for the organisation’s sponsorship activity and the actions of staff or representatives who use the Sponsorship Management System.
The organisation’s principal point of contact with UK Visas and Immigration.
The person responsible for most day-to-day management of the sponsor licence through the Sponsorship Management System.
An organisation may also appoint Level 2 Users with more restricted SMS access once the licence is in place.
These positions should be selected carefully.
Problems involving key personnel can affect the organisation’s ability to obtain or retain its licence.
The Sponsorship Management System, commonly known as the SMS, is the online system used by licensed sponsors to administer their sponsor licence.
Employers use the SMS for matters including:
The Home Office expects licensed sponsors to use the system properly and report relevant changes within the required timescales.
For example, significant organisational changes such as mergers, takeovers, insolvency or substantial changes to the nature of the business can carry specific reporting obligations.
A Certificate of Sponsorship, commonly referred to as a CoS, is an electronic sponsorship record assigned by an authorised sponsor to a worker.
It is not a physical certificate.
Each Certificate of Sponsorship has its own reference number, which the worker uses when making the relevant immigration application.
The CoS contains important information about the proposed sponsored employment.
This can include:
The worker normally has a limited period in which to use the CoS for their visa application.
Incorrect CoS assignment can create problems both for the worker’s immigration application and for the employer’s compliance position.
The type of Certificate of Sponsorship required depends upon the worker and immigration application.
Defined CoS are generally required for Skilled Worker applicants applying from outside the UK.
The sponsor requests these through the Sponsorship Management System before assigning them to the worker.
Other Worker-route applications generally use certificates from the sponsor’s annual or available allocation.
Before assigning any CoS, the employer should check:
The fact that a sponsor has access to a CoS does not mean it should automatically assign one.
A sponsor licence creates continuing responsibilities.
Licensed sponsors must maintain appropriate systems for monitoring sponsored workers and complying with Home Office requirements.
Sponsor duties can include:
Sponsorship should therefore be treated as an ongoing corporate compliance function, not simply an immigration application process.
A successful sponsor licence application will normally result in an A-rated sponsor licence.
An A-rated sponsor can assign Certificates of Sponsorship for eligible roles.
If the organisation later fails to comply with its responsibilities, its licence can potentially be downgraded to a B-rating.
A B-rated sponsor may be prevented from assigning new Certificates of Sponsorship until it makes the required improvements and returns to A-rated status.
A downgrade can therefore have immediate consequences for recruitment.
UKVI can carry out compliance checks before or after granting a sponsor licence.
A Home Office visit may assess whether the business:
Businesses should therefore remain audit-ready throughout the life of their sponsor licence.
Waiting until a Home Office visit is announced before reviewing compliance can leave very little time to correct systemic problems.
A proactive sponsor compliance audit can help identify weaknesses before they become Home Office concerns.
A compliance audit can include reviewing:
An internal audit can be particularly useful before:
The Home Office can suspend a sponsor licence where it believes that the organisation may have failed to comply with its sponsorship obligations.
Suspension can be extremely serious.
It can affect an organisation’s ability to sponsor new workers while the Home Office investigates.
The employer may be given an opportunity to respond to the allegations and provide supporting evidence.
A response should address the Home Office’s concerns directly and explain any corrective action taken.
Because suspension can progress to revocation, businesses should treat correspondence from UKVI as urgent.
Sponsor licence revocation is one of the most serious outcomes for a licensed employer.
If the licence is revoked, the organisation loses its ability to sponsor workers under the affected routes.
This can affect:
The Home Office can downgrade, suspend or withdraw a sponsor licence where sponsor responsibilities are not met.
Where revocation is threatened or has occurred, the business should obtain advice promptly.
A sponsor licence application can be refused where UKVI is not satisfied that the requirements have been met.
Potential problems can include:
Previous refusals and revocations can also affect the timing of future applications. Current Home Office eligibility rules include cooling-off periods in certain circumstances.
The reasons for refusal should therefore be understood before another sponsor licence application is submitted.
Every UK employer should have appropriate procedures for checking whether employees have permission to undertake their proposed employment.
A compliant right to work process can involve:
For sponsor licence holders, evidence of right to work checks forms part of wider sponsorship compliance.
Right to work checks should therefore form part of the employer’s ordinary recruitment and HR procedures.
Employers can face serious consequences where they employ an individual who does not have the right to undertake the work concerned.
Depending upon the circumstances, consequences can include:
Where a civil penalty is issued, the employer should consider:
A civil penalty can also have implications for a sponsor licence.
A compliant international recruitment process can involve several separate stages.
Some workers already have permission to work without employer sponsorship.
The employer must hold the appropriate licence for the immigration route concerned.
The proposed role must be suitable for sponsorship.
The code should properly reflect the actual duties of the role.
The proposed salary must satisfy the immigration requirements applying to the worker and occupation.
The CoS must accurately reflect the sponsored employment.
The worker must independently satisfy the relevant immigration requirements.
Sponsorship does not guarantee that a worker’s visa will be granted.
The employer must establish the worker’s permission before employment begins.
The employer must continue to satisfy its sponsor duties throughout the sponsored employment.
The Global Business Mobility framework provides specialist immigration routes for workers based overseas who are undertaking temporary assignments in the UK.
The five principal routes are:
For qualifying senior managers or specialist employees transferring to a UK business linked to their overseas employer.
For qualifying employees taking part in structured graduate training involving a UK placement.
For senior managers or specialist employees helping an overseas business establish a UK presence.
For qualifying overseas service suppliers and certain self-employed professionals delivering services under eligible international trade commitments.
For qualifying workers coming to the UK in connection with certain high-value contracts or investments.
The Global Business Mobility routes are temporary and are not themselves direct routes to settlement.
Businesses should therefore consider the immediate assignment and the worker’s longer-term immigration strategy separately.
Corporate changes can have significant sponsor-licence consequences.
A sponsor should consider immigration compliance where there is:
Certain significant changes must be reported to UKVI, including mergers, takeovers and substantial changes to the nature of the business.
Sponsor-licence implications should therefore form part of corporate due diligence where a business employs sponsored workers.
Common issues can include:
Many of these problems can be identified through proactive compliance work before they result in Home Office enforcement.
