Determine the eligibility of your family member for a family-based Green Card, which may include immediate relatives such as spouses, parents, or unmarried children under 21.

File Form I-130, Petition for Alien Relative, with USCIS to establish the family relationship and petition for your family member's immigration.

Wait for the petition to be approved, which may involve a waiting period depending on the relationship and country of origin.

Apply for an immigrant visa or adjust status, depending on whether your family member is currently in the U.S. or abroad.

Attend an interview and receive a decision on the Green Card application, which may involve background checks and additional documentation.
