How long can I return to China after immigrating to Canada?

Your present conditions are far from immigration. You'd better wait until you find an employer after graduating from a Canadian university and work in Canada for one year before applying for immigration. After applying for immigration, you can apply for naturalization in Canada for three years in the first five years and retain the right of abode after two years. If you have been naturalized in Canada and no longer have China nationality, you need a visa from the China Embassy when you return to China. There are no restrictions on returning to China for development. In other words, if you stay in Canada for less than two years during the five years in the immigration prison, you will lose your immigration status. There is another way, that is, if your parents are qualified to immigrate to Canada and ask your parents to apply for immigration, you can immigrate as a whole, and you will naturally immigrate (you will come back for an interview and a physical examination when your parents interview). And studying in Canada can save a lot of money. That's all I know.
