What forms need for a green card holder petitioner for a child to immigrate to the US under the whole process?

Currently this preference category has a backlog of approximately 4-5 years for natives of any country other than Mexico and the Philippines. You can begin by filing the I-130 petition for alien relative with appropriate documentation which includes a copy of your permanent residence card, proof of your son’s birth, and proof that you were either married to his mother at the time of his birth or that he was legitimated by you before he turned the age of 18. After filing with USCIS, you will receive a receipt and then hear nothing from the agency for a long time until it reaches and adjudicates your petition. Assuming that it is approved, USCIS will transfer the approved petition to the National Visa Center, which acts as a halfway house between USCIS and the American consulates and embassies. The Center will then begin requesting other documents to prepare an interview for your son. When the priority date is current, the consulate or embassy should invite him for an interview, and if he passes, give him the appropriate documentation to enter the US as a permanent resident.
