Sponsored worker visa applications require more than an assigned Certificate of Sponsorship. The worker must submit the correct immigration application and independently satisfy the eligibility, identity, suitability and supporting-document requirements of the relevant route.
James Immigration Solutions Ltd assists sponsored workers and UK employers with application preparation, CoS verification, supporting evidence and Home Office requirements.
A sponsored worker application is the visa or permission-to-stay application submitted by a worker after an approved UK employer assigns a Certificate of Sponsorship.
A CoS supports the application but does not grant immigration permission or guarantee approval. The worker must complete a separate online application and meet the requirements of the relevant sponsored work route.
We can provide assistance with straightforward applications under routes such as:
Each route has different requirements. Eligibility should be reviewed before the worker submits an application or pays Home Office fees.
A worker outside the UK will normally apply for entry clearance using a valid CoS assigned by an approved sponsor.
The application must be submitted within the validity period of the CoS and through the correct overseas application process.
Some individuals already living in the UK can switch into the Skilled Worker route. However, switching is prohibited from certain categories, including:
Applicants who cannot switch must normally leave the UK and apply from overseas. The current restrictions are explained on the official Skilled Worker switching page.
An extension may be appropriate where the worker:
Different salary or occupation rules may apply to workers who have continuously held Skilled Worker or former Tier 2 permission since an earlier date.
A Skilled Worker will normally need to update their immigration permission where they:
The new employer must assign a new CoS before the worker applies.
A worker can generally continue working in their existing sponsored job while a timely change-of-employment application is pending. However, they should not start the new sponsored job until the Home Office confirms the new permission. Further information is available in the official change of employer guidance.
A Skilled Worker applicant must normally demonstrate that:
The applicable requirements depend on the CoS assignment date, occupation, salary option and the worker’s previous immigration history.
Most new Skilled Worker applicants must demonstrate English-language ability at least at level B2 in reading, writing, speaking and listening.
English can potentially be demonstrated through:
Limited transitional arrangements apply to some workers who held Skilled Worker permission before 8 January 2026. The current requirements are explained on the Skilled Worker English-language page.

We review:
Before preparing the application, we check the CoS information against:
Where an issue is identified, the sponsor may need to correct it through a permitted sponsor note or take another appropriate action before submission.

We assist with preparing the relevant online application and checking information about:
The applicant remains responsible for checking the completed form and confirming that all declarations are accurate before submission.
We provide a personalised document checklist and review the available evidence before submission.
Documents may include:
The official Skilled Worker document list confirms the core documents normally required.
Depending on the route, an applicant may need to pay:
Health and Care Worker applicants may be exempt from the Immigration Health Surcharge if they meet the requirements of that route.
Applicants may also need to demonstrate sufficient maintenance funds unless:
Current application costs should always be checked using the official Skilled Worker fees guidance.
After the application is submitted, the worker will normally prove their identity by either:
The application system will explain which process applies.
We can assist with document-upload preparation and post-submission correspondence. Biometric appointments and Home Office decision-making remain outside our control.
An applicant submitting from inside the UK should be mindful of the following:
Travelling outside the UK, Ireland, the Channel Islands or the Isle of Man before a decision is made will normally cause an in-country application to be treated as withdrawn.
A sponsored worker must normally use the CoS within three months of the date it was assigned.
The worker must also not apply more than three months before the employment start date recorded on the CoS.
An application may be rejected or refused where the CoS:
The current timing requirements are confirmed in the Home Office Skilled Worker sponsor guidance.
The Home Office currently states that a Skilled Worker decision is usually made within:
These times generally run after the applicant has proved their identity and provided the required documents. Applications can take longer if documents require verification, an interview is required or the case contains complex circumstances.
Priority services may be available, but faster processing and a particular outcome cannot be guaranteed. Applicants should check the current UK visa processing times before making travel or employment arrangements.
Common problems include:
A pre-submission review can identify many of these issues before Home Office fees are paid.
No. A Certificate of Sponsorship confirms that an employer wishes to sponsor the worker for the role recorded on the CoS.
The Home Office separately assesses whether:
Neither the employer nor an immigration adviser can guarantee that an application will be successful.
