I would urge you to consult with and hire an immigration lawyer to assist you with this case. You can sponsor your step-son (may need release from father - or possibly not, since he abandoned child) An immigration lawyer can debrief and brief you, analyze, assess and evaluate your case in order to maximize the possibilities for a successful result. Your wife would have to consular visa process in Ciudad Juarez with an I-601A waiver filed after you petition for her. Rather complicated - you really need an immigration lawyer.
