The only real difference is that we have defined which provinces are dealt with by Hong Kong and by Beijing in the family class, and only in the family class. In that category we deal with the southern part of China, which is primarily Cantonese-speaking, while Beijing deals with the rest of China.
For all other immigration applications—all categories, including investors, skilled workers, provincial nominees, and Quebec cases—we share responsibility with Beijing, and it is the applicant who decides where to apply.
