Just immigrated to Canada, can I return to China at any time? I heard that you can't go back to China for two or three years, right?

You can return to China at any time according to your personal needs; However, some immigrant countries have applied for permanent residence permits, which are generally valid for five years. When your permanent residence permit needs to be renewed, the Immigration Bureau will evaluate the time for you to change your residence. If you live for less than two years within five years, it may have a negative impact on the extension of your permanent residence permit.
