individuals who entered the U.S. without inspection cannot adjust their status to become a lawful permanent resident (get a green card) based on a U.S. citizen child's petition, unless they qualify for a specific exception like INA 245(i) or a waiver of inadmissibility

To sponsor a family member for a Green Card, you, as a U.S. citizen or lawful permanent resident, need to file Form I-130, Petition for Alien Relative, with USCIS.

You'll also need to demonstrate your ability to financially support the sponsored family member. The process involves proving your relationship to the applicant and ensuring they meet the eligibility requirements for a Green Card.
