What is the Affidavit of Support (Form I-864) and who has to file it?

Most immediate relative and family-based preference immigrants are considered inadmissible as likely to become a public charge unless an Affidavit of Support, Form I-864, is submitted on their behalf. The petitioning sponsor generally must file it and demonstrate sufficient income or assets to support the immigrant.

The I-864 is a legally enforceable contract in which the sponsor agrees to maintain the immigrant at a required income level. If the sponsor's income is not enough, a joint sponsor may sometimes be used. This financial requirement is a core part of family-based cases and a common reason applications are delayed or denied, so sponsors should confirm they meet the current income thresholds.
