Applying alone then adding the family

hi all

o thought to have some of your input on my dilemma. I am in a common law situation and 3 kids. my partner works full time in office setting. so I thought I should apply solo, get approved and get all my situation sorted and then add the kids and the partner after when she changes her job to remote.

ultimately they will all be added within the year. I am trying to find the best way to get approved
