Yes, it is very confusing and it is a long story.
I have been living with my partner more than 1 year.
when we have our baby, (April 30, 2023) we had 6 months living together.
In regards the marital status, I was told by CRA that after the born of my child, I was in common law, probably this is different from IRCC, but because of that I changed my status in IRCC while I was waiting for my final decision, also, at that moment (October 12, 2023) I sent a letter explaining them that I applied much before I had a family and I was not intended to get PR for my partner since she was applying on her own for Refugee, and our child is Canadian (certificate provided as well).
As I mentioned, the email from IRCC I just got it a few hours ago and they are asking me for the Kit Application Forms, but last week I got the access to the PR Portal. So I believe probably IRCC just attended and responded me in regards the letter I had sent in October, 2023, but I am not sure how I should proceed because my intention now is to sponsor my partner since her refugee case was denied.
