Affidavit of Support Guide: Meeting the Income Requirements

Updated April 2026 · By the VisaCalcs Team

The Affidavit of Support, Form I-864, is one of the most consequential documents in family-based immigration, yet many sponsors underestimate its importance and legal weight. It is a legally enforceable contract between the sponsor and the U.S. government, promising to financially support the immigrant at 125 percent of the federal poverty guidelines. Failure to meet the income requirement does not just delay the case. It can result in outright denial. This guide explains the income thresholds, how assets can supplement income, when a joint sponsor is needed, and the long-term obligations sponsors take on.

Income Thresholds and Poverty Guidelines

The sponsor must demonstrate household income at or above 125 percent of the federal poverty guidelines for their household size. Household size includes the sponsor, their dependents, and the immigrant being sponsored. For a household of four in 2024, the minimum income is approximately $38,000 per year. Active-duty military sponsors qualify at 100 percent instead of 125 percent.

Income is demonstrated through the most recent federal tax return, current employment verification, and pay stubs. If the sponsor's income has increased significantly since the last tax return, a current employer letter stating salary and position strengthens the case. Self-employed sponsors must provide tax returns with all schedules and may need additional business documentation.

Using Assets to Supplement Income

If the sponsor's income falls below the threshold, assets can make up the difference. For family-based petitions, the assets must equal at least three times the gap between the sponsor's income and the required amount. For sponsor's spouse petitions, the multiplier is only one times the gap.

Qualifying assets include savings accounts, stocks, bonds, real estate equity, and retirement accounts that can be readily converted to cash within one year. The primary residence is not counted unless its equity exceeds the mortgage by a significant margin. Each asset must be documented with bank statements, property appraisals, or brokerage statements from within the last 12 months.

Joint Sponsors and Household Contributors

When the primary sponsor cannot meet the income requirement alone, a joint sponsor can file a separate I-864 to cover the gap. The joint sponsor must be a U.S. citizen or permanent resident who meets the income threshold independently for their own household size plus the sponsored immigrant. The joint sponsor takes on the same legal obligations as the primary sponsor.

Household contributors are different from joint sponsors. A household member who lives with the sponsor and has income can contribute to the household income calculation by filing Form I-864A. This person does not need to independently meet the poverty guidelines but does accept legal responsibility for supporting the immigrant.

• Primary sponsor: must file I-864 in all family-based cases
• Joint sponsor: files separate I-864, meets threshold independently
• Household contributor: files I-864A, adds income to sponsor total
• Co-sponsor: not an official USCIS term; use joint sponsor correctly

Long-Term Obligations

The I-864 obligation lasts until the immigrant becomes a U.S. citizen, is credited with 40 qualifying quarters of work, dies, permanently leaves the United States, or is removed and readmitted as a permanent resident. Divorce does not end the obligation. The sponsor remains financially responsible even after a marriage ends.

Government agencies that provide means-tested benefits to the immigrant can sue the sponsor for reimbursement. This includes benefits like Medicaid, food stamps, and cash assistance. The immigrant can also sue the sponsor directly if they fail to provide adequate support. These are not theoretical risks. Courts have enforced I-864 obligations in multiple cases.
