Overseas Processing (OP)
OP 2 Processing members of the family class
5.19. Medical requirements
Members of the family class are medically inadmissible if they or their family members are likely to
be a danger to public health or to public safety or if their admission might reasonably be expected
to cause excessive demands on health or social services [A38(1)]. See Exceptions to medical
inadmissibility, Section 5.20 below.
Instructions on medical examinations can be found in OP 15. That chapter also explains how to
interpret medical results to determine if the applicant is medically admissible and the steps to take
before informing applicants that they are refused for medical reasons.
If a member of the family class or a family member is found to be inadmissible for medical
reasons, and no new information is provided (see OP 15), the application should be refused.

5.20. Exceptions to medical inadmissibility
A38(2)(a) states that spouses, common-law partners and dependent children who are members of
the family class are not inadmissible even if they have a medical condition that will result in
excessive demand to health or social services.
R24 provides further exemption from medical inadmissibility that might reasonably be expected to
cause excessive demand on health or social services for conjugal partners and children to be
adopted.
