File against a rollout schedule the client has actually committed to, and treat the five-year maximum as the outer boundary of the whole plan. A material change in where the specialist works or who directs her is not a scheduling detail; it can require a fresh look at the petition rather than a simple extension.
The assignment described is the assignment authorized
Implementation dates in health care slip for reasons nobody controls, including clinical governance approvals and the reluctance of busy practices to switch systems mid-quarter. Two responses are safe and one is not. It is safe to delay the filing until the clinic group has committed to a phased schedule with dates.
It is safe to file for a shorter period matched to the first phase and seek an extension supported by evidence of the work performed. It is not safe to leave Ingrid at a client site doing something other than what the petition described because phase one was postponed, particularly if the clinics begin directing her day. Track the cumulative time she spends in this classification from the first admission, since the five-year ceiling is reached sooner than most teams expect when assignments are extended twice.
