Does the petitioner have to file an affidavit of support if he or she cannot meet the income requirements and there is a joint sponsor?
Yes, the law requires that the petitioner must be a sponsor and file an Affidavit of Support, even if he or she cannot meet the income requirements. The petitioner remains fully liable, along with the joint sponsor, for any benefits the sponsored immigrant(s) may use. The joint sponsor must file a separate Affidavit of Support.
