Unfortunatley, to petition for him, he would have to be considered your stepfather under the immigration laws, meaning his marriage to your mother had to occur before you turned 18 years old. What is your mother's status? If she is a U.S. citizen, she may be able to petition for him and, since he entered legally, he may be eligible to adjust his status (apply for a green card). If she is not a U.S. citizen or green card holder yet, you could explore whether she is eligible through your petition for her. Also, do you have any U.S. citizen siblings who were under 18 when your mom married your "stepfather" and are now 21 years or older?
