Landed in Quebec, Canada, and didn't live for 3 years. . . problem

If you said that you entered Canada with an immigrant visa, then:

1, you can return to China at any time without going through the formalities, but you need to enter Canada with a maple leaf card to return to China again. At this time, he is still a citizen of China. Insurance in China depends on what insurance you had in China. The situation of subsidies is not clear.

I don't know the difference between five years and three years. However, if you stay in Canada for less than two years in five years, you may lose your immigration status, that is, the maple leaf card will not work (there are exceptions, but it is usually the case). You can apply for Canadian citizenship if you have lived in Canada for three years within four years. After joining, you can apply for a Canadian passport and have the right to vote and stand for election. At this time, legally speaking, you have lost your China nationality. In many cases, you will be forced to cancel your China account and hand in your Chinese identity card.

3. Whether you want to go to the United States or other countries, you should handle it according to the situation of China citizens. In other words, you still have to apply for a visa to the United States at the American embassy or consulate in Canada, but the possibility of getting a visa is greater than that of applying at home.
