Form I-864: Affidavit of Support

Form I-864, the Affidavit of Support, is a legally binding contract in which a sponsor promises the U.S. government to financially support an intending immigrant so the immigrant does not become a public charge. The petitioner who filed the family-based immigrant petition must submit Form I-864 for the relative seeking a green card, and additional joint sponsors may be required if the petitioner's income is insufficient. The sponsor agrees to maintain the immigrant at an income of at least 125 percent of the Federal Poverty Guidelines and signs under penalty of perjury. The affidavit is required in most family-based immigrant visa and adjustment of status cases under the Immigration and Nationality Act (Section 213A). Because the obligation is enforceable, the sponsor should understand that signing creates real financial and legal duties that continue after the immigrant becomes a permanent resident, not merely a formality for the application.

The Form I-864 obligation lasts until the sponsored immigrant becomes a U.S. citizen, has been credited with 40 qualifying quarters of work (about ten years), permanently leaves the United States, or dies, whichever comes first. Divorce does not end the obligation; a sponsor remains financially responsible for a former spouse who immigrated based on the affidavit until one of the terminating events occurs. The duty also survives changes in the sponsor's circumstances, so a job loss or new family obligations do not release the sponsor. Because the affidavit is a binding contract with the government under the Immigration and Nationality Act, the sponsored immigrant or a government agency that provides means-tested public benefits can sue to enforce it. Sponsors should weigh this long-term commitment carefully before signing, since the financial responsibility can extend for many years regardless of how the personal relationship evolves.

Sponsoring an immigrant on Form I-864 generally requires the sponsor to show household income of at least 125 percent of the Federal Poverty Guidelines for the household size, which includes the sponsor, dependents, the immigrant, and anyone previously sponsored. Active-duty members of the U.S. armed forces sponsoring a spouse or child need only meet 100 percent of the guidelines. The guidelines are updated annually and vary by household size and state, so the sponsor must use the current figures and the correct household count. If the sponsor's income falls short, options include counting the income of qualifying household members through Form I-864A, using significant assets valued at several times the shortfall, or adding a joint sponsor who independently meets the requirement. Because the thresholds change each year, the sponsor should verify the current poverty guideline amount for the applicable household size before submitting the affidavit.

The financial obligation under Form I-864 can be enforced against the sponsor, because the affidavit is a legally binding contract created under Section 213A of the Immigration and Nationality Act. The sponsored immigrant can sue the sponsor directly to recover support up to the 125 percent poverty level, and government agencies that provide means-tested public benefits to the immigrant can seek reimbursement from the sponsor. Courts have upheld these obligations even after divorce, treating the affidavit as a separate enforceable promise to the government rather than a private agreement that the parties can waive. The obligation continues until a terminating event, such as the immigrant naturalizing or earning 40 work quarters. Because of this exposure, anyone considering becoming a sponsor or joint sponsor should understand that signing Form I-864 may create years of financial liability that a court can enforce, independent of the underlying family relationship.

A joint sponsor is needed for Form I-864 when the petitioning sponsor cannot meet the required income of at least 125 percent of the Federal Poverty Guidelines for the household size on their own. A joint sponsor is a separate individual, a U.S. citizen or lawful permanent resident over 18 residing in the United States, who independently meets the income requirement and signs a separate Form I-864 accepting the same binding support obligation. The joint sponsor's income alone, not combined with the petitioner's, must satisfy the threshold for the relevant household size. The petitioner still must file their own affidavit even when a joint sponsor participates. Because the joint sponsor takes on the full, enforceable financial responsibility under Section 213A of the Immigration and Nationality Act, this person should understand the commitment before signing. Sponsors short on income may alternatively use qualifying household members or assets to bridge the gap.
