Yes, a candidate can start working full time as soon as the VISA is granted, even if this is before the work start date.
📌 Key Points:
The CoS start date is the intended start of employment but is not legally binding once the visa is approved.
What matters most is that the candidate has been granted the visa - this is what gives them the right to work.
🛑 Reminder:
Candidates must not begin working before their visa has been approved - regardless of what the CoS states.
