One thing I also received with the SA email is yet another form that I have to complete and send back "Family Information Sheet for Sponsorship under R 117(1)h" which includes a table for information about all my relatives (siblings, aunts, uncles, parents, grandparents, nieces, nephews). The requested information in the table includes names, dates of birth/death, and addresses!
Did anyone here receive this sheet too? I'm not sure how I can collect all that information! I mean getting the dates alone is a big challenge. I have no idea what some of those birth dates are!
