What are the ages of the adult children? Do they have any children of their own? CIC has different requirements depending on age and marital status. If they meet any of the conditions below (it is a cut and paste from the CIC Guide), they will need to be "examined" (have medicals and police checks) even if they are not coming to Canada.
Definitions of dependent child (types A, B and C)
Your child or the child of your spouse or common-law partner can be considered a dependent child if that child meets the requirements of types A, B or C below:
TYPE A
The child is under the age of 22 and is single (not married and not in a common-law relationship).
TYPE B
The child has been continuously enrolled in and in attendance as a full‑time student at a post‑secondary institution accredited by the relevant government authority and has depended substantially on the financial support of a parent either:
since before the age of 22, or
since marrying or entering into a common-law relationship (if it happened before the age of 22).
TYPE C
The child is 22 years of age or older, has depended substantially on the financial support of a parent since before the age of 22, and is unable to provide for himself or herself because of a medical condition.
