Step 1: Obtain a Sponsor Licence

Before you can sponsor an overseas worker, you need a sponsor licence from the Home Office. If you already have one, check that it is active and rated A-rated.

The sponsor licence application process takes approximately 8-12 weeks and requires you to demonstrate that your business is genuine, operating lawfully, and has appropriate HR systems to manage sponsored workers.

Check the difference between A and B-rated sponsors to understand the compliance implications.

Step 2: Confirm the Role Is Eligible

The role must meet the Skilled Worker visa requirements:

  • The job must be at RQF Level 3 or above (A-level equivalent or higher).
  • The role must have a valid SOC (Standard Occupational Classification) code. Check the eligible jobs list.
  • The salary must meet the salary threshold and the going rate for the occupation.

Step 3: Assign a Certificate of Sponsorship

Once you have identified your candidate, assign them a Certificate of Sponsorship (CoS). This is done through the Sponsor Management System (SMS). The CoS includes details about the job, salary, and the worker.

There is a CoS fee per certificate. Ensure all details are accurate, as errors can delay the visa application.

Step 4: Support the Visa Application

The worker applies for their Skilled Worker visa using the CoS reference number. As an employer, you should:

  • Provide the worker with the CoS reference number and any supporting documents they need.
  • Pay any employer-funded costs (visa fee, IHS, etc.) if your agreement covers these.
  • Allow time for visa processing before setting a start date.
  • Understand the Immigration Skills Charge payable by the employer.

Step 5: Right-to-Work Check

Before the worker starts, conduct a right-to-work check. This is a legal requirement for all employees. For sponsored workers, use the Home Office online checking service with the worker's share code.

Failing to conduct a right-to-work check can result in civil penalties and damage to your sponsor licence.

Step 6: Onboarding

Help your new employee settle in:

Step 7: Ongoing Compliance

Your duties do not end when the worker starts. As a sponsor, you must:

  • Keep records of the worker's contact details, attendance, and immigration documents.
  • Report changes to the Home Office (change of role, salary, absences, etc.) through the SMS reporting system.
  • Conduct follow-up right-to-work checks before the worker's visa expires.
  • Cooperate with any Home Office audit.

Here is a summary of typical employer costs for hiring one overseas worker:

  • Sponsor licence: 536 pounds (small) or 1,476 pounds (medium/large)
