If your employer has paid the Defined Certificate of Sponsorship (CoS) fee and the Immigration Skills Charge, it is common to feel unsure about what happens next. Many applicants expect the certificate to be issued immediately, only to find there is a waiting period with little visibility. Understanding the steps that follow can help you feel more confident about where your application stands and what to expect next.
This guidance explains the process in plain English, focusing on how Defined CoS applications are handled under UK immigration rules.
Understanding the issue or context
For overseas Skilled Worker visa applicants, a Defined Certificate of Sponsorship is required before a visa application can be submitted. This certificate is requested by the employer, not the worker, and is managed through the Home Office’s Sponsor Management System.
Although payment of the relevant fees is an important step, it does not mean the certificate is issued instantly. The Defined CoS must still be assessed and approved by the Home Office before it can be assigned to the worker.
This period of waiting often causes confusion, particularly where start dates or relocation plans are involved.
The legal rules or framework
Under UK immigration rules, the process for a Defined CoS involves several stages.
The employer must submit a request through the Sponsor Management System, providing details about the role, salary, and the individual being sponsored. Once the request is submitted and the relevant fees are paid, the Home Office reviews the application.
The Home Office may:
- Approve the Defined CoS
- Request further information
- Take additional time to carry out checks
There is no guaranteed timeframe for approval. While some Defined CoS requests are processed quickly, others can take several weeks depending on workload and whether further scrutiny is required.
Only once the Defined CoS is approved can it be formally assigned to the worker, enabling them to submit their Skilled Worker visa application.
Practical steps to take
While waiting for the Defined CoS to be issued, there are practical steps that can help reduce delays later.
First, the employer should regularly monitor the Sponsor Management System for updates or requests for further information. Prompt responses can prevent unnecessary delays.
Second, the worker can prepare their visa application documents in advance. This may include identity documents, evidence of qualifications, and any other supporting material required for the Skilled Worker visa.
Third, it is sensible to avoid booking travel or making irreversible plans until the Defined CoS has been issued and the visa application submitted.
If delays become prolonged or unclear, fixed-fee legal advice can help clarify whether the process is progressing normally or whether further action may be appropriate.
Common pitfalls to avoid
A common misunderstanding is assuming that payment of fees means the Defined CoS has been granted. In reality, approval still depends on Home Office assessment.
Another pitfall is overlooking requests for additional information within the Sponsor Management System, which can pause or delay the process.
It is also important not to submit a Skilled Worker visa application before the Defined CoS has been formally assigned, as this will result in refusal.
