If the petitioner of a preference immigrant dies after the principal sponsored family member has immigrated but before a family member qualifying to ‘follow to join’ the principal immigrant has immigrated, another sponsor, acting and qualifying as a ‘joint sponsor,’ may file an Affidavit of Support on behalf of that immigrant.
Note: Take the example of a parent who petitions for her married daughter and her family to immigrate. The daughter and children immigrate immediately, but the husband chooses to wait for another year. A new Affidavit of Support signed by the petitioner would be required for the husband at the time he immigrates, but this would not be possible if the petitioning parent had died. In this instance, a ’joint sponsor’ would be permitted. In the case of an immediate relative, since each immediate relative family member is the beneficiary of a separate visa petition, a new petition and Affidavit of Support would be required.
