I am totally agree with Master7 and others.
They are very slow. I have sent my updated documents 15 days before and it received at BIQ HK before 7 days. And i have asked them to verify whether they have received my documents or not, and after 5 days they replied me as below.
For your information, The Ministère de l'immigration et des Communautés culturelles wishes to inform its clientele that as of April 1, 2013, the selection of skilled workers will be officially transferred form BIQHK to our office in Montréal. Please check our website for the update information.
This information is just useless.
