I am a U.S. citizen. My daughter's father is from Brazil. We were never married. He came to the U.S. in the middle of 2005 on a visitor's visa. We had our daughter in the middle of 2008. He left the country a week later; so he overstayed his visa by more than 2.5 years. He worked under the table while he was here. He does not have any criminal history either here or in Brazil. I know that people who overstay their visas and want to return to the U.S. face a 10 year ban. Does the fact that the person has a child in the U.S. change this at all? If so, how and when can he return to the U.S.? Thank you very much for your assistance.
