Payroll and T4 records prove continuous employment; the appointment letter and dated organization charts show when the role became managerial. The year abroad must be in a managerial, executive or specialized-knowledge capacity, so the promotion date matters as much as the hire date.
Date the capacity, not just the employment
Hypothetical example: the service manager joined the Kent dealer as a technician five years ago and was promoted to run the service department fourteen months before the planned petition. The continuous year of employment is easy to prove, but the regulation requires that year to have been in a qualifying capacity. Assemble the promotion letter, the organization chart before and after it, the payroll change that accompanied it, and examples of decisions he has made since: hiring a technician, approving warranty claims, signing a service contract. If the promotion came only nine months ago, the petition is early, and no description of his earlier technician years fills the gap. Also gather the corporate documents—share register, incorporation records and the U.S. entity's formation papers—because the year abroad only counts if it was with a company that has the required relationship with the U.S. branch.
Hypothetical example: a surgical-instrument distributor promoted its employee after an acquisition, but the payroll system retained his former title for three pay periods. The first review flags the mismatch and obtains the acquisition records, promotion letter, revised chart and a payroll explanation. The dates and capacity must form one coherent chronology. Leaving the discrepancy unexplained can make a genuine qualifying year appear shorter than it is.
