The first step in obtaining a green card for an eligible family member is to file a petition with the United States Citizenship and Immigration Services (USCIS). The petition is known as a Form I-130 and requires you to provide your information, the beneficiary’s information, and your relationship to the beneficiary. You will be required to prove your U.S. citizenship or status as a U.S. lawful permanent resident and provide an affidavit stating that you will be financially responsible for the immigrant. Your beneficiary will also be required to undergo health and background screenings.
