A sponsored child's PR application was refused because the officer determined the applicant was not a member of the family class. The child had claimed that they were 20 years old, but on the sponsor's own application 2 years ago, they had declared that their child was 26 years old. During the interview with their RCIC, the sponsor insists that the applicant is their biological child. What should the RCIC request to prove the relationship?

While a certified copy of a birth certificate can indicate parentage, it may not resolve discrepancies effectively, particularly when the ages stated differ significantly. In this case, the previous application claiming the child was 26 years old raises questions that a birth certificate alone cannot clarify, especially if the dates appear inconsistent.

A notarized affidavit from the applicant may provide a personal declaration of their relationship, but such statements can be subjective and do not serve as conclusive proof of biological ties. This choice would not adequately address the doubts raised by the officer regarding the applicant's true age and familial connection.

Similar to the applicant's affidavit, a notarized affidavit from the sponsor would only offer their assertion of the relationship. However, it does not provide objective evidence to counter the inconsistencies found in previous applications, leaving the officer's concerns unaddressed.
