I’m a U.S. citizen who’s been living in France for the past ten years, married to a French citizen for the past six. It’s the second marriage for both of us. My husband has a son from his first marriage, who just turned 19. He lives with us and I consider him my stepson. My husband and I are planning to move to the U.S. so that I can be with my elderly parents. The issue is that our son is in his first serious relationship, with another young man, and doesn’t want to come to the U.S. without him. He’s been insisting that if he marries his boyfriend, he can bring him along. When we try to tell him that’s not the way U.S. law works, he tells us we’re being unsupportive. Please clarify this!
