I-864 Affidavit of Support - Part I

Generally all persons who immigrate through a family member must have a qualified I-864 filed on their behalf by the petitioner. [1] By completing the I-864, the petitioner/sponsor is assuring the government that the intending immigrant is either (1) financially self-sufficient and thus will not need public assistance, or (2) has family who will agree to financially support the immigrant at 125% of poverty level. [2]

Who May Submit the Affidavit of Support

A person who submits an affidavit of support is called the sponsor. In order to be a sponsor, one must:

  1. Be a citizen or national of the US or a permanent resident;

  2. Be at least 18 years of age; and

  3. Live in the United States or a US territory or possession

Moreover, the petitioner must be a sponsor and submit an affidavit of support on behalf of the intending immigrant regardless of the sponsor's actual ability to support the intending immigrant.

Determining 125% of the Poverty Income Guidelines

A sponsor signing the affidavit of support must demonstrate that he/she earns enough income to support the immigrant and sponsor’s entire household at 125% above the federal poverty income guidelines. [3] To determine the size of the household that must be counted in calculating the 125% poverty level, the following persons must be included as part of the household:

  1. The sponsor;
  2. All persons who live at the same residence as the sponsor and who are related to the sponsor by birth, marriage, or adoption;
  3. Any dependents whom the sponsor has claimed on a sponsor's most recent federal income tax return - even if they do not live with the sponsor;
  4. All noncitizens included in the current affidavit of support; and
  5. All noncitizens previously included in an I-864 affidavit of support unless the obligation has ended. [4]
