My boyfriend is applying for a visitor's visa. He supports his retired parents financially, who live with him. I am wondering what kinds of documentation are considered the most compelling to prove this to CIC.
Proofs: He and his parents live at the same address + he pays the rent or mortgage + property tax receipts + utility bills + parents' medical expenses + parents' insurance policies + credit card bills + if he gives them money for their expenses.... (Whatever is applicable.... 2-3 of these will suffice)
