When we first received the email stating our application was complete we noticed they had our old address in the header, despite the fact we had moved and used the online address change tool 4 months prior to the application being complete, so we called the CIC to confirm they had our correct address on file, which they did not. But the person we spoke to at the CIC assured us that the Vancouver office had not sent anything by mail yet in regards to the PR Interview.
The person at the CIC we spoke to did not seem very sure of what they were saying so a couple days later we called again to make sure our address had been changed, and it had, but this time this person said they had no way of knowing if the Vancouver Office had tried to contact us or not at our old address.
We have faxed both the Howe and Expo Blvd CIC offices in Vancouver, with no reponse. I have not bother emailing the CIC yet because it seems you just get a generic response to be patient.
As several other people are experiencing waits times similar to ours I am not worried yet, just frustrated that after 16 months we are stalled on the final step, while other people with the same postal code as us, who applied after us, got their PR interview a week after a decision had been made.
