Answer: notify the broker-dealer of the change within 30 days
Step-by-step explanation:
From the question, we are informed that client of a member broker-dealer has just found a new job requiring relocation with a salary paying 50% more than the old job.
Based on the above scenario, the client has to notify the broker-dealer of the change within 30 days. This is because when significant changes to the status of a client, the firm has to be notified by the client within 30 days.
