You need to be using a bit of logic to put everything together. A lot of the info on the website, such as that defintion, is generic, applying to every immigration class. You need to put it together with the specific information in the spousal sponsorship guide.
I would like to thank you for all your insights and guidance. I have one last query to ask you about. I have declared my partner on my express entry application for PR, and put her down as non-accompanying. Now, after spending two weeks only in Canada, I am returning to apply to sponsor her. The reason I have provided as to why she is not accompanying was because of her job situation at the time. Could our application be rejected on these grounds? Do I need to provide an explanation why I haven't applied with her in the first instance and wanting to sponsor her in such a short span of time?
