You will need to submit an i-130 to USCIS to petition for your son along with proof of your citizenship and relationship to your son, such as birth certificates, marriage certificates, passport, etc. If the petition is approved, it will be sent to the National Visa Center for further processing of his immigrant visa application, civil documents, and affidavit of support before he is finally scheduled for an visa interview at the US consulate in Manila.
