What was the process of moving back to your home country with your?
My state has a relocation process. I have primary custody because my ex wife violated it (so take it seriously). The departing parent has to notify the other parent in writing of the intent to relocate. If that parent objects, the moving parent has to show that the move is in the childs best interest. As a practical matter, youll need to adjust the parenting plan to accommodate the distance. If you do that and both sign off, it should be fine to relocate.
