Most 221g will be cleared, matter of time. I got one in Toronto ( i would not go to toronto again, 221g for no reason). My stamp has the word "canadian permanent resident" as well and i was specifically asked about this during the interview. Also, 221g i received has nothing to do with the PR thing
Per what i see, all(most PRs applying for any type of visa) do receive the annotation as "Canadian PR" in the visa. Possibly the reason for 221g would have been something else as some other member mentioned, we dont know the whole story.
But i am not shocked to see if some visa officers behave in that way in this new era of immigration restriction(which triggers many guys to take action on their own).
In some other locations, visa officers even throw the documents out of the window hence they dont behave nice all the time hence its also mood and circumstantial for most denial/RFE.
Can i know your 221g? Just trying to see we can avoid the same.
FYI - my 221g: I was asked to provide proof of 140 filed as i mentioned that my employer has filed immigration petition. So you guys should take the copy of receipt/approval(or at least have the receipt number) just in case. if you are mailing the documents then just keep the 140 receipt/approval copy.
