If I want to immigrate to Canada, where should I go to go through these procedures?

There are many kinds of immigrants in Canada, and the applicable objects and conditions are different. Go to official website first, and CIC (Canadian Immigration Department) will learn about the types and conditions of these immigrants and see what kind of immigrants they have. Then prepare the application materials and submit the application in accordance with the provisions of CIC. If you are a domestic resident, you should submit an application to the Canadian Embassy in Beijing. If you entrust an intermediary to handle it for you, the place of submission may be the embassy in Beijing or the Canadian Consulate General in Hong Kong.
