What are the conditions for a Canadian green card?

After all the information and conditions of the applicant are qualified, the Canadian Immigration Bureau will issue an "immigrant visa" to the applicant, which is also commonly known as "immigration paper". "Immigration paper" in multiple copies is a legal visa to apply for entry into Canada; With this document, the applicant can successfully leave the original country of residence and declare to Canadian customs or ports, which is called "entry and landing"; At this time, the Canadian immigration officer there will sign the "immigration document" and give the applicant a page. This document becomes the legal status of the applicant to settle in Canada for a long time, which is equivalent to the "green card" of the United States. Immigrants who hold this page document are called "permanent residents", "landed immigrants" or "new immigrants" in Canada; People in Chinese mainland and Taiwan Province Province who have this status have changed from this status to "overseas Chinese", but they continue to hold passports issued by their original countries of residence. Canadian law stipulates that "permanent residents" enjoy the same rights as Canadian citizens in business, employment, study and further study, social and medical benefits, except that they cannot participate in elections and voting; At the same time, we should bear the same obligations as Canadian citizens, such as paying taxes according to regulations and obeying laws and regulations. In Canada, there is no difference between "permanent residents" and "Canadian residents" in doing business and getting employment, studying and enjoying social medical benefits. You only need to hold a "social insurance card" to go through various formalities. After being registered in Canada for three years, a "permanent resident" can apply to become a "Canadian citizen" and obtain a Canadian passport if he has no major criminal negligence. A "green card" or "permanent resident status" held by a "permanent resident" has no validity limit. As long as it does not violate Canadian laws and regulations, you can keep your "green card" for decades, or you don't need to apply for "Canadian citizen" status. Canada recognizes dual or multiple nationality, so some people in Canada maintain dual or multiple nationality. The China government prohibits its citizens from maintaining dual citizenship. Therefore, once Chinese mainland immigrants to Canada have settled in Canada for three years and obtained Canadian citizenship, they are considered to have lost their China citizenship and are no longer subject to the jurisdiction and protection of China laws.
