Unfortunately, there’s a high chance her immigration application depends on her being married to him. My husband and I have been at his process for going on 8 years, and it entirely rests on me sponsoring him. If we were to separate, his whole case would get shut down, and he starts over with an even more expensive and complicated process. We aren’t going to divorce because we love each other, but it’s still something that his lawyer had to advise us about.
