"Could you clarify my understanding about the March 2025 EOI-(June 2023-491 Visa) data showing 2,687 total applications on hand: If we assume an approximate ratio of 1.5 secondary applicants per primary applicant, would this mean there were roughly 1,075 primary applications (or cases) being processed by case officers? I understand this is an approximation since the ratio could vary - with some primary applicants having 2 or 3 secondary applicants, others having just 1 secondary applicant (minimum), and some having no secondary applicants at all."@ gregor-need ur advice
