Total the per-person amounts for everyone who will be in the application, then add the costs a staggered move creates on top: two households running at once, repeated travel, storage, and duplicated professional or medical fees. Whether the program charges separately for family members and how it handles children who are close to the cutoff are matters the official FAQ addresses and which should be read on the day of application rather than assumed from a summary. Beyond money, each family member is assessed for admissibility on their own record, and children are subject to the age-21 rule, with the Child Status Protection Act applying only as the law provides for the underlying category.
