Form I-864 Guide: Affidavit of Support Requirements Explained
One of the most misunderstood parts of family-based immigration is the financial sponsorship requirement. Form I-864, Affidavit of Support, is a legally enforceable contract required in many family-based cases to show the intending immigrant has adequate financial support and is not likely to rely on certain means-tested public benefits (U.S. Citizenship and Immigration Services [USCIS], 2025a; U.S. Department of State, 2026a).
Mistakes in the Affidavit of Support are one of the most common reasons for delays and Requests for Evidence (RFEs), especially when household size or qualifying income is miscalculated, documents are incomplete, or the wrong sponsor documents are submitted (USCIS, 2025b).

What Form I-864 Is Designed to Do
Form I-864 is a contract between the sponsor and the U.S. government to support the intending immigrant if needed. By signing, the sponsor agrees to use financial resources to support the immigrant and, in certain situations, a benefits-granting agency may seek reimbursement from the sponsor as permitted by law (USCIS, 2025a; U.S. Department of State, 2026a).
Official filing requirements and instructions are published directly by USCIS at i-864: i-864.
How Long the Sponsorship Obligation Lasts
Sponsors often do not realize how long the commitment can continue. The obligation generally lasts until the immigrant becomes a U.S. citizen, earns 40 qualifying quarters of work (often described as about 10 years), permanently departs the United States, or dies. Divorce does not end the obligation (U.S. Department of State, 2026a).
When Form I-864 Is Required
Form I-864 is generally required in immediate relative cases and many family preference cases, and it may also be required in certain employment-based cases where a relative petitioned for the intending immigrant (USCIS, 2025a; U.S. Department of State, 2026b).
It is commonly required during:
• Adjustment of Status (Form I-485) inside the United States
• Consular processing through the National Visa Center (NVC)
Who Must Submit Form I-864
The Primary Sponsor
The petitioner who filed the family-based petition generally must submit Form I-864, even if their income is not sufficient and a joint sponsor will also be used (U.S. Department of State, 2026a).
Joint Sponsor
If the petitioner’s income does not meet the minimum requirements, a joint sponsor may submit a separate Form I-864. A joint sponsor must generally be a U.S. citizen or lawful permanent resident, be at least 18 years old, be domiciled in the United States, and qualify independently based on household size and income (U.S. Department of State, 2026a; USCIS, 2025b).
Income Requirements in 2026
Sponsors generally must show income at or above 125% of the HHS Poverty Guidelines for the sponsor’s household size. Certain active-duty military sponsors petitioning for a spouse or child may qualify at 100% (USCIS, 2024a; U.S. Department of State, 2026a). Poverty guideline amounts can change annually, so always verify the current chart before filing (Office of the Assistant Secretary for Planning and Evaluation, 2026).
How Household Size Is Counted
Household size can include the sponsor, the sponsor’s spouse, dependent children, anyone claimed on taxes, the intending immigrant(s), and certain previously sponsored immigrants still under obligation (USCIS, 2025b).
What If Income Is Not Enough?
Joint Sponsor
A joint sponsor can meet the income requirement independently by submitting a separate Form I-864 (U.S. Department of State, 2026a).
Household Member Income
In some cases, a household member who lives with the sponsor may contribute qualifying income by filing Form I-864A, depending on the case facts and eligibility rules (U.S. Department of State, 2026a).
Using Assets
Some cases allow assets to supplement income. Assets must generally be readily convertible to cash within one year, and the value needed can vary depending on the relationship and category (USCIS, 2025b).
Required Supporting Documents
Most I-864 filings commonly include the sponsor’s federal tax return, proof of current income, and evidence of status (citizenship or permanent residence). Consular processing cases typically require documents to be uploaded to the NVC as directed (USCIS, 2025b; U.S. Department of State, 2026a).

Common I-864 Mistakes That Trigger RFEs
Common issues include using outdated guideline figures, miscalculating household size, submitting incomplete tax documentation, forgetting signatures, providing inconsistent income information across documents, and using a joint sponsor who does not qualify independently (USCIS, 2025b; U.S. Department of State, 2026b).
Adjustment of Status vs. Consular Processing
The I-864 stage looks different depending on the case type. For adjustment of status, Form I-864 is typically submitted with the I-485 package and reviewed by USCIS during adjudication. For consular processing, the I-864 is generally submitted through the NVC portal, and incorrect uploads or missing documents can delay NVC review (USCIS, 2025b; U.S. Department of State, 2026a).
Public Charge Considerations
While Form I-864 is an important financial sponsorship tool, it is not the only consideration that may be reviewed in public charge-related analysis for certain applicants. USCIS policy explains that a sufficient Form I-864 does not eliminate the need to consider other required factors where the public charge ground applies (USCIS, 2025c). Consular officers may also evaluate additional factors affecting the applicant’s overall financial situation (U.S. Department of State, 2026b).
