Dependent children are individuals who meet these criteria in connection to an immigration applicant:
1. They are the biological or adopted child of the applicant.
2. They are below 22 years old.
3. They are not married or in a common-law relationship.
In certain circumstances, if the child is 22 years or older but relies on the applicant for financial support due to physical or mental health reasons, they may still be considered dependent children.
