My husband has 3 children with a former partner. His son is under his legal custody, and his daughters under his ex's. Although he has custody of his son, his son has often lived with other family members. We were planning on putting all 3 as non-accompanying children, with the intention of perhaps later sponsoring his son to come, after we've settled our life out a bit (a couple of years likely). Now I'm wondering if we should instead list him as accompanying in order to facilitate the matter, even if he does not stay with us in the end? From what I understand, he would need to come with his father when he first comes, but then could go back to his home country and extended family? Any thoughts on the matter?
