What Changed? 

The May 1, 2026, update provides clearer instructions on: 

Eligible Change Requests 

The Home Office reaffirmed and clarified that only specific licence updates qualify for priority processing, including: 

• Adding a new Level 1 User 
• Replacing an Authorizing Officer 
• Replacing a Key Contact 
• Updating organization details, such as: 
  • Company name 
  • Business address

Submission Process and Capacity Limits 

The guidance clarifies that: 

• Sponsors must first submit the change in the Sponsor Management System (SMS). 
• Only after submitting the change can they request priority processing. 
• The service accepts a limited number of requests per working day, on a first‑come, first‑served basis. 
• Sponsors will receive an email confirming whether their request has been accepted. 

This update reinforces the importance of early‑day submissions due to capacity constraints.
