My foreign-born wife (with my children) and I endured months of separation at severe financial expense so we could get her papers in order before she came to America. I have no sympathy for someone who doesn't bother to do it legally.
They're blaming the separation on the government when they should be blaming him. Or blame his wife for not forcing him to get legal before they married and had a child who would suffer the consequences of his dad's decisions.
I suggest the system is fixed so neither you nor anyone else has to suffer family separation.
