You can file an appeal,Since you cannot sponsor somebody under a departure order,You can work on his papers ASAP ,But if there is a departure order,He has to go,Have you appealed?
That is NOT correct! Please don't disinform the OP.
You have nothing to worry about. I have been refused as a Conventional refugee and since than my wife is sponsoring me and nobody asked me to leave, nobody WILL as long as she is sponsoring me. The reason why letter states that a PRRA app will be sent at a later date is for them to have time to check if there is any other valid reason for your husband to remain in Canada. And your sponsorship is a damn valid reason, trust me. As long as CIC RECEIVES! your signed sponsorship BEFORE! CBSA invites your husband for a PRRA assessment
, you will be fine. In another words, you're the only one who's keeping your husband in Canada. So he better treat ya right!!!
