Should you also mention somewhere the duration/time the spouse has been apart? I am sure if they see there are people with 18/20/22/24 months of separation - that's going to have some impact.
Also, somewhere we will need to mention that spousal sponsorship/family reunification is being worked on by IRCC - however, express entry family unification falls in a different category and IRCC has not yet prioritised these applications. Because if you just say - family reunification, Marco Mendicino is going to say that we are already working on it - which is not accurate
