What is i-130 form used for

The I-130, Petition for Alien Relative, is a form used by U.S. citizens and lawful permanent residents (green card holders) to establish a qualifying family relationship with a foreign relative who wishes to immigrate to the United States. Filing Form I-130 is the first step in obtaining a family-based green card, and approval of the petition confirms the legitimacy of the relationship but does not grant immediate immigration benefits. Once approved, the beneficiary (foreign relative) can proceed with the visa or adjustment of status process based on their eligibility and visa availability.
