A fictional situation

Arjun’s next decision

Arjun's next course starts after a summer break, and he has been planning around the university calendar alone. When he compares that calendar with his current immigration permission, he sees that they answer different questions. He asks the university about the new sponsorship details and records the dates that affect his proposed application.

His funding evidence also needs a fresh review. Arjun's next step is to establish whether and how an extension fits his circumstances before treating a new CAS as the complete answer. If his status or history raises a complication, he needs an appropriate assessment promptly.

Identify the existing permission

Check the precise status and expiry before discussing an in-country application. Level 1 leave-to-remain work is ordinarily limited to applicants with current leave, subject to specified exceptions.

Review academic and sponsor details

A new course, sponsor or changed circumstances may create requirements different from the original application. Ask the sponsor to confirm relevant information.

Prepare evidence in the right order

Collect only relevant, current evidence. Do not treat possession of an old CAS, bank statement or biometric record as proof the extension criteria are met.

Escalate rather than improvise

An expired visa, disputed academic progress or a previous refusal may require higher-level assessment. We screen those issues before proposing an engagement.

Key takeaways: what to do next

  • Start here. Compare permission expiry, course dates, sponsorship and evidence requirements before assuming an in-country extension is available.
  • 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.
