Hello there,wow that’s some good news. My wife also got a call yesterday oct 5 from the Rabat and they told her that they will send her a letter by mail. Agent said: your medical is about to expire in december. Would you be interested to go before that date to Canada? She said yes of course. He said ok .. you will get a letter by mail. He confirmed her mailing address. And he said have a nice day. What do you think that letter could be ?!Did you receive the interview letter by mail?
That is a good sign! i really hope that i m not wrong but based of what you just mentioned, i strongly believe that they will be sending her the pre-arrival instructions and ask for her passport to be stamped.
best of luck!
