I would urge you to consult with and hire an immigration lawyer to assist you with this case. I don't think you’re capable of handling it. The lawyer will be able to debrief and brief you, analyze, assess and evaluate the case in order to maximize the possibilities for a successful result. I believe a juvenile court petition as an abandoned child should be filed for SIJS benefits which may lead to a greencard.
