FAMILY PETITIONS
To petition for a family member to receive a Green Card (permanent residence), begin by filing Form I-130, Petition for Alien Relative. This form establishes the family relationship that exists between you and your relative. Sometimes the I-130 can be filed together with an application for permanent residence, officially known as Form I-485, Application to Register Permanent Residence or Adjust Status.
