Renewing your work permission starts with what has changed.

A fictional situation

Ben’s next decision

Ben opens his last application and expects to update the date. Since that application, his responsibilities and pay have changed, and the employer uses a different job title. He makes a list of those changes alongside his current permission and asks the employer to clarify the proposed sponsorship details.

The next step is to assess the present job and current rules, not reproduce an old file. If a past immigration issue or a disputed point appears, Ben raises it at screening. This makes the scope clearer before anyone accepts the work or treats the extension as automatic.

Check your current permission

A straightforward in-country extension should begin with the applicant’s current immigration permission, its expiry and any relevant sponsorship change. IAA Level 1 guidance ordinarily limits leave-to-remain work to clients with extant leave, subject to specified exceptions.

Do not assume an extension repeats the original application

Rules, evidence and sponsor arrangements can change. Confirm the current route requirements before using old documents or reusing another applicant’s advice. A different employer, changed occupation or unusual immigration history may warrant closer scrutiny.

Know when to refer

An expired permission, refusal requiring legal representations or a contested issue may be outside our direct Level 1 work. We would not accept the matter merely because it has been described as an extension.

Separate costs and scope

We distinguish professional fees from visa charges and other disbursements, confirm our specific tasks in writing and only accept instructions after a suitability assessment.

Key takeaways: what to do next

  • Start here. Compare today's role, pay and sponsorship with current permission instead of copying the previous application.
  • If the facts are clear, compare them with the current official guidance below and list the evidence still needed. Keep the purpose of each document clear.
  • If a fact is uncertain or disputed, flag it before submitting or paying for application work. Ask whether the issue needs an adviser with different authorisation or experience.

An enquiry does not extend a deadline or confirm that we have accepted instructions. For an urgent matter, seek appropriately authorised help promptly.

Frequently asked questions

What should I check about my existing work permission?

A straightforward in-country extension should begin with the applicant’s current immigration permission, its expiry and any relevant sponsorship change. IAA Level 1 guidance ordinarily limits leave-to-remain work to clients with extant leave, subject to specified exceptions.

Why might a Skilled Worker extension need fresh evidence?

Rules, evidence and sponsor arrangements can change. Confirm the current route requirements before using old documents or reusing another applicant’s advice. A different employer, changed occupation or unusual immigration history may warrant closer scrutiny.

When should an extension case be referred?

An expired permission, refusal requiring legal representations or a contested issue may be outside our direct Level 1 work. We would not accept the matter merely because it has been described as an extension.

Are professional fees separate from government charges?

We distinguish professional fees from visa charges and other disbursements, confirm our specific tasks in writing and only accept instructions after a suitability assessment.

Does Level 1 cover every Skilled Worker extension?

No. Suitability turns on the particular facts, scope and adviser competence.

Can I book and pay without a review?

The first enquiry is screened before any paid casework is accepted.

What is the practical lesson from Ben’s example?

Compare today's role, pay and sponsorship with current permission instead of copying the previous application. The example is fictional and does not establish eligibility or predict a decision in another case.
