Oh, thanks PMM - that's good to know about the RPRF! What about the sponsorship fee, would they have to pay one for each application?
Nicen - The outland sponsorship application that I linked to in my reply, and that PMM linked to above, are the forms you need for sponsoring both children.
If their passports were not stamped on entry, it's going to make it more difficult for you to prove when the children first entered Canada for purposes of extending their status. Do you have airline tickets/itinerary - or perhaps stamps in your own passports that you could use, if you can show they accompanied you? This is something that frequently happens to US citizens on entry to Canada - I think they do it on purpose to make it harder for us to apply from within Canada for extension of status.
