In that case, I would try to call and talk to an agent to make sure that information does get through to IRCC.Hi, thanks for replying! Yes we stated clearly in the reply that my parents are in China and they don't have Canada visitor visas as those expired. We are now worried about whether the reply got through to the visa office. We replied again to their follow-up portal email. If things go through, will it be the Etobicoke office that issues passport request? Thanks again!
I believe the local VO will issue the PPR. But I am not sure.
