To include a household member’s income, the household member and sponsor must together complete and
sign the Form I-864A Contract Between Sponsor and Household Member. As the name suggests, this is a
contract between the contributing household member and the sponsor. In that contract, the household
member agrees to be jointly and severally liable for all of the sponsor’s obligations under the Affidavit of
Support. In other words, the household member would be just as responsible as the sponsor would be if the
sponsor were sued and had to pay out money.
Unlike other household members, the intending immigrant does not have to sign an I-864A, as long as s/he is
immigrating by herself (i.e., she is not immigrating with a spouse or child).
