My son who is american married a canadian girl in the US six years ago. They resided in the Us and had two children born here (US) . My DIL applied and received her US Green Card. They decided to move to Canada 4 months ago and began the application for a spousal visa for my son. Now they have decided to divorce and my son is wondering if he will be forced to leave Canada, and leave his daughters with their mom? She is only working part time and cannot support all of them. Anyone have any info that I could pass along to him?
