The sponsor guidance generally asks for changes to a sponsored worker (such as a change of role, work location or salary falling below the Certificate) to be reported within 10 working days, and for organisational changes within 20 working days of becoming aware. Some reports have different deadlines, so read the guidance for your case.

We count the day after the event as working day 1, and treat Saturdays, Sundays and the bank holidays of the nation you choose as non-working days. The guidance is the authority: if in doubt, report sooner.
