Absolutely - no need to pay that kind of money!!! Good grief! The most you should have to pay is $5. There is information on exactly how to get your CAIPS at this Immipedia link.
Thanks for the links. I still don't really understand under what circumstances I would request this --- if our spousal sponsorship application is unsuccessful? Or would I request this if my husband is called for an interview? Could someone please clarify for me? Thank you.
