Navigating the process of hiring foreign workers in the UK can be complex, especially when it comes to the Certificate of Sponsorship (CoS) allocation. As an employer, you need to understand how many CoSs you can assign and the requirements surrounding them. A CoS is essential for sponsoring a non-UK migrant worker and must be allocated correctly to ensure compliance with immigration laws.
The allocation of CoSs is tied to your sponsor licence and can impact your ability to bring in skilled talent from outside the UK. Each year, employers must manage their CoS allocation effectively to meet their staffing needs while adhering to Home Office guidelines. Familiarising yourself with the rules and procedures for CoS allocation will make the process smoother and help you recruit the right candidates.
By understanding the ins and outs of CoS allocation, you position your business for success in a competitive market. This article will break down the key points you need to know, ensuring that you can navigate the CoS system with confidence.
Overview of the Certificate of Sponsorship
The Certificate of Sponsorship (CoS) is a vital tool for employers in the UK looking to hire skilled workers from abroad. Understanding its definition and the different types will help you navigate the sponsorship process effectively.
Defining Certificate of Sponsorship (CoS)
A Certificate of Sponsorship (CoS) is an electronic record that employers must assign to each foreign worker they intend to hire. It is essential for applying for a visa under the UK's Points-Based System. The CoS contains details such as the worker's personal information and the role they will perform.
This document enables you to sponsor non-UK migrants for various work roles. It shows that you are compliant with immigration rules and that the role meets specific skill requirements. Each CoS is unique and must be allocated to a specific individual within three months of assignment.
Types of CoS: Unrestricted and Restricted
There are two primary types of Certificates of Sponsorship: unrestricted and restricted CoS.
Unrestricted CoS is typically for roles that meet certain criteria, such as being skilled or listed in shortage occupations. You do not need to apply for this type through the monthly allocation process. You can assign these to workers who are already in the UK or those switching from other visas.
Restricted CoS, on the other hand, is for roles that don’t meet the criteria for unrestricted CoS. You must apply for this type through a monthly allocation system. It is more common for entry-level positions or those not listed in shortage occupations. Understanding which type your role falls under is crucial for a smooth hiring process.

The Sponsorship Management System (SMS)
The Sponsorship Management System (SMS) is a vital online portal used by UK employers for managing sponsorship duties. Understanding the roles within the SMS and the compliance requirements is essential to ensure smooth operations.
Roles within the SMS: Authorising Officer, Key Contact and Level 1 User
In the SMS, different roles help manage sponsorship.
Authorising Officer: This person is responsible for the overall sponsorship process. They ensure that the company complies with UK visa regulations and oversee the actions of other users within the system.
Key Contact: This role acts as a liaison between the company and UK Visas and Immigration (UKVI). The Key Contact handles communication and keeps the Authorising Officer informed about important updates or changes.
Level 1 User: These users carry out everyday tasks within the SMS. They can create and assign Certificates of Sponsorship (CoS) and manage workers’ details. They follow guidelines set out by the Authorising Officer.
Compliance and Sponsor Duties
Maintaining compliance is crucial for all users in the SMS.
Your duties include:
Record Keeping: You must keep accurate records of all sponsorship activities and ensure all information is up to date.
Report Changes: If a foreign worker's circumstances change, you are responsible for reporting these changes to UKVI. This could include changes in work location or job title.
Monitoring: You must monitor the attendance and performance of sponsored workers to prevent any compliance issues.
Failure to meet these duties could lead to penalties or loss of your sponsor licence. Understanding your responsibilities helps ensure a smooth experience in managing sponsorship.
Allocation and Request Process for CoS
Understanding the allocation and request process for Certificates of Sponsorship (CoS) is crucial for employers. You need to know how to allocate CoS properly and the steps to submit a request to ensure compliance with UK immigration laws.
Understanding CoS Allocation
CoS allocation is essential for employing foreign workers. Each employer must request a specific number of CoS based on their needs. This allocation is managed through your sponsor licence, which outlines how many CoS you can issue.
Your compliance team plays a vital role in this process. They ensure that your organisation meets all UK Visa and Immigration (UKVI) requirements. It is your responsibility to justify the number of CoS requested by showing the need for skilled workers. This includes detailing roles, salary levels, and the potential impact on your business.
Submitting CoS Allocation Requests
When you submit a CoS allocation request, it’s done through the online sponsor management system. You will select the option to request additional CoS and must complete a form that details your requirements.
Be prepared to explain the reasons for your request thoroughly. This can include business plans, growth forecasts, and other documentation that supports your case. Ensure your compliance team reviews all materials before submission to avoid delays or rejections.
After submitting, you will typically receive a response from UKVI confirming your allocation. Keep records of your requests for future reference, as these may be necessary for inspections or audits.
Visa Application and CoS: Skilled Worker Visa Journey
The process of applying for a Skilled Worker Visa requires the use of a Certificate of Sponsorship (CoS). Understanding how to link your CoS with your visa application is crucial, as is knowing the immigration permissions and requirements that come with it.
Linking CoS with the Skilled Worker Visa Application
To initiate the visa application, you need a valid Certificate of Sponsorship from your employer. This document provides proof that you have a job offer from a UK-based company. Your employer will assign the CoS electronically through the UK Visas and Immigration (UKVI) system.
When you apply, you must include the CoS reference number. It's important that your CoS aligns with the job you are applying for. If there are discrepancies, your application might be refused. Make sure to keep a copy of the CoS for your records, as it contains key information about your sponsorship and the job duties.
Immigration Permissions and CoS Requirements
Your Certificate of Sponsorship is linked to specific immigration permissions that allow you to work in the UK. With a CoS, you must apply for the Skilled Worker Visa within three months of receiving the certificate. If you delay, the CoS may expire, and you would need a new one.
Additionally, the CoS must reflect the appropriate details, such as your job title, salary level, and skill level. The job must meet the criteria set by UKVI. Ensure that you provide accurate information during your visa application, as any errors could lead to delays or a refusal of your immigration permission.
Sponsoring an International Workforce: Compliance and Best Practices
Navigating the process of sponsoring overseas employees involves understanding legal obligations and implementing best practices. Following proper guidance ensures compliance and helps your business thrive in a competitive international landscape.
Guidance for Businesses on Sponsoring Overseas Employees
When sponsoring foreign workers, you must be familiar with the UK regulations set by the Home Office. This includes understanding the types of visas available and how to assign a Certificate of Sponsorship (CoS) effectively.
Key considerations include:
Ensure that the employee meets the eligibility criteria for the visa you're sponsoring.
Keep detailed records of the employment terms, including job descriptions and salary details.
Regularly review the sponsor guidance to stay updated on any changes.
You may also want to consult a law firm for overseas business to access tailored guidance and ensure compliance with immigration laws. This approach minimizes risks and enhances your organisation's stability in sponsoring international talent.
Legal Responsibilities and In-House Training
As an employer, you hold legal responsibilities that must be met to maintain your sponsor licence. You must comply with all relevant laws and ensure that your HR team is trained to handle immigration matters effectively.
Consider implementing in-house training sessions that cover:
Visa application processes and compliance checks
Responsibilities for monitoring sponsored employees
Consequences of failing to comply with Home Office requirements
This proactive approach not only protects your business but also equips your team with essential skills. For a successful UK business trip or ongoing sponsorship, understanding these responsibilities is critical to your future in business immigration.
