No, no update on the status. Per the message from CIC "CPC-Sydney does not provide processing times or details of the case to applicants regarding cases referred to Program support Unit as they vary on a case-by-case basis. Your application has been placed in queue awaiting assessment by a senior officer because of a policy or legislative issue pertaining to the case."
Guate,
I'm in the exact same situation as you. They received my application on October 2, 2017 and sent me an acknowledgement of receipt, with a case number, on October 30, 2017. Since then nothing, and my online ECAS only shows Application Received.
I called IRCC Call Centre today and an agent looked into my case for me. He confirmed that my application has been sent to the Program Support Unit for a decision and that they sent me a letter by e-mail notifying me of this. I told him I never received this letter. He also said that if Program Support Unit is involved, it can take up to two years and in the mean time they can do nothing at the Call Centre.
I was shocked, I didn't know what to say. Well, I told the agent I
could speed up the process by purchasing air travel tickets and claiming urgent processing. Although I'd rather not do that, it would be nice to be able to go visit my parents in my birth country. He said that was my choice, although there's no guarantee that they'll grant the request for urgent processing. This totally sucks!
