Social Security has guidelines for who qualifies for SSI benefits.
It depends on a person's age, disability and financial resources.
The rules are different for children. They change at age 18 because a person is considered an adult.
Note: The parents' income will not count if a child does not live at home. (For example, if the child lives at a residential school.)
We'll explain all of this in more detail in the next section!
