How long will Canadian immigration supervision last?

You can apply for naturalization if you have lived in Canada for three years within five years. You must take the exam (very simple), then take the oath, and finally change your passport (Canada) and Canadian citizen card. Alas, you are a Canadian, not a China, and you will be an overseas Chinese when you come back.

You can retain your permanent resident status if you live for two years within five years.

When landing for the first time, the main applicant must enter the country before or with the deputy applicant; Otherwise, the deputy applicant can't enter the country before the main applicant, and then the main applicant can do whatever he wants. However, if he wants to keep his resident status, he must follow the above rules, otherwise his resident status will be cancelled. If you can prove that you have a job outside Canada, the Canadian government can make a decision according to the situation.

If you are signed, there is a time limit on the landing paper, and you must enter the country before this time limit. If you can't enter the country before this time limit, then this visa and landing paper will be invalid and you can't enter the country. If you want to enter the country, I'm sorry, you must submit a new visa application.

That's all I know. I wonder if it will help you.
