Hello Everyone, I have a situation here. My Mom is a single mom when she had me, and now both my mom and grandparents (mom’s side) are deceased. I’m sponsoring my niece from my half-sister who I grew up with, she reached biometrics and medical part already and now they are asking death certificates for both my parents and grandparents even on my dad side (who I never knew my whole life). I won’t be able to provide this as I have no information about them. I never mentioned my dad on all my application even applying for Permanent Residence and Citizenship. Now I don’t know what to do as I don’t have proof about my dad what should I do?
