Lady from my local MP office called IRCC. I am Jan 11 2016 applicant. By May 11th, I finished 16 months.
They requested updated Schedule A form in Sep 2016 and I provided them documents within Two weeks through case specific enquiry. Due to lack information and additional documents were requested, they could not able to process file within 16 months. They need 3 to 4 months extra to review the complete file again.
Simply they told me to wait till end of Aug 2017. My local MP office requested them to process the file fast, if possible.
WTH....I am going to file EE.
