My friend was living illegally in the US over 10 years ago. He had a child with a woman, who called the police in a domestic issue, and end result he signed his voluntary deportation. He left, and she then attempted to request him with an I-129f, but at that time did not have the financial backing, and was denied. He returned to the US illegally and has lived here ever since.
Does he have a 10 year ban?? Does he have a lifetime ban?? Is it possible for his fiance now to enter an I-130 and I-485, or what are his chances at all. Is it a lost cause??
