Hi my bother in law has been using a SSN for work for over 6 yrs it turned out that the SSN he was usin was that of a minor child. He found out when he tried to fie for unemployment. The lady told him she had to contact immigration asap he got scared and left. He has been married over 5 years and has a 4yr old son. What will most likely happen and what can I do to help him stay with his son and wife who has disabilities and can not raise their son on her own. Will this hurt his chances of being able to become legal?
