Three things: a qualifying corporate relationship with both entities actively doing business, one continuous year of Marise's qualifying employment abroad within the preceding three years, and that her role is primarily managerial or executive rather than operational.
Company, history and duties, in that order
Each element is proved with different material, and they fail for different reasons. The relationship is a documents exercise: parent, branch, subsidiary or affiliate, evidenced by share registers and corporate records, with both companies genuinely trading. The year abroad is a payroll exercise: continuous, within the three years before the petition, with the qualifying organisation, and in a qualifying capacity.
The capacity finding is the argumentative one, because it asks what Marise principally does rather than what her business card says. Managerial capacity turns on directing the organisation, a department or an essential function, supervising professional or supervisory staff, and holding authority over personnel and daily operations. Executive capacity turns on directing management and setting policy under wide latitude.
A candid, proportionate account of her operational involvement is far stronger than a description that pretends she has never touched a machine.
