Yes. An Affidavit of Support, which is also called the Form I-864, is a document that an individual (called the sponsor) signs to confirm that they accept financial responsibility for the applicant who is coming to the United States to live. The petitioner is required to complete the Affidavit of Support; however, if their income is insufficient, a joint sponsor can also agree to complete a form on the applicant’s behalf.
It is important to know that the Affidavit of Support is legally enforceable. Typically, a sponsor will retain financial responsibility until the applicant either becomes a United States citizen or is credited for 40 qualifying quarters of work under the Social Security Act.
