Form I-864: The Complete Guide to the Affidavit of Support

The Affidavit of Support, formalized through Form I-864 from USCIS, is the document that transforms a petitioner’s promise into a legally enforceable contract with the United States government. Without it properly completed, virtually no family-based green card moves forward: consular officers and USCIS adjudicators treat it as an eligibility prerequisite, not a mere attachment. This guide details when the I-864 is required, who can sign it, what minimum income is accepted in 2026, how the related forms work, and which errors sink solid cases at the consulate or in the adjustment of status interview.

What the Affidavit of Support Is

The Affidavit of Support is a sworn declaration in which a U.S. citizen or lawful permanent resident assumes financial responsibility for the sponsored immigrant. The legal basis is found in Section 213A of the Immigration and Nationality Act, regulated under 8 CFR 213a. The stated purpose is to prevent the beneficiary from becoming a public charge, meaning dependent on federal means-tested benefits.

Unlike a recommendation letter or a good-faith declaration, the I-864 creates an enforceable obligation. The immigrant themselves and certain federal agencies can sue the sponsor in civil court to recover amounts if the beneficiary receives public assistance or is not adequately supported.

When the I-864 Is Required

Form I-864 is required in most family-based petitions: spouses (CR-1, IR-1), parents of U.S. citizens (IR-5), children (IR-2, F2A, F2B), siblings (F4), and family preference categories. It also applies to employment-based cases where a close relative owns 5% or more of the petitioning company.

It is waived in a few specific situations: widows or widowers remarrying U.S. citizens who have more than 40 qualifying work quarters on record, children who automatically acquire citizenship under the Child Citizenship Act upon entering the U.S., and self-petitioners under VAWA in specific circumstances.

Form Variants

USCIS publishes three versions of the Affidavit of Support, each for a distinct scenario:

• I-864: the standard version, used when the sponsor needs to demonstrate eligibility alone or together with co-sponsors.
• I-864A: an additional contract between the primary sponsor and a household member whose income will also be counted toward meeting the required income threshold. Without the I-864A, the relative’s income cannot be included.
• I-864EZ: a simplified version available only when the petitioner is sponsoring a single beneficiary, meets the income minimum alone using salary from a single employer (reported on a W-2), and does not need a joint sponsor.
• I-864P: not a form to fill out; it is the annual poverty guidelines table published by USCIS based on figures from the Department of Health and Human Services (HHS).

Minimum Income Required in 2026

The sponsor must demonstrate annual income equal to or greater than 125% of the Federal Poverty Level for their household size, including the sponsored immigrant. For sponsors on active duty in the Armed Forces sponsoring a spouse or child, the floor drops to 100%.

The figures published in the I-864P in effect in 2026 (based on the HHS 2025 Poverty Guidelines applicable to the 48 contiguous states and DC) are as follows:

The floors for Alaska and Hawaii are higher. Always confirm the current figures in the I-864P published by USCIS before submitting, because the table is updated annually and pending cases are evaluated against the guideline in effect on the interview date, not the petition date.

How to Compose Income

The computed income is the total income from line 9 of the most recent federal Form 1040. Sponsors may combine:

• Their own income from wages, self-employment, rent, alimony received, and dividends.
• Income from household members who sign the I-864A.
• Liquidatable assets converted to income equivalent, at a ratio of 5 to 1 (or 3 to 1 when the beneficiary is a spouse or child of a U.S. citizen). If the sponsor has a US$ 10,000 income shortfall, they would need US$ 50,000 in documented assets (or US$ 30,000 in the case of a spouse or child of a USC).
• The immigrant’s own assets, if accessible and transferable to the U.S.

Joint Sponsor

When the petitioner does not meet the minimum, a joint sponsor can sign a separate I-864 assuming full responsibility, as if they were the primary sponsor. The joint sponsor must independently meet the 125% threshold for their own household plus the immigrant. Combining the petitioner’s income with the joint sponsor’s income is not permitted.

I-864 vs. I-134

Form I-134 is also an affidavit of support, but it serves non-immigration contexts: humanitarian parole, visitor visas in specific situations, refugees, and programs such as Uniting for Ukraine and the CHNV process. The I-134 does not create an enforceable obligation until naturalization, and the required income is typically more flexible. Confusing the two is a recurring mistake: using the I-134 where the case requires the I-864 leads to a Request for Evidence or denial.

Supporting Documents

The I-864 alone is not sufficient. The complete file includes:

• Copy of the most recent federal tax return (Form 1040 with all schedules and W-2 or 1099).
• IRS transcript when requested, downloaded from irs.gov/individuals/get-transcript.
• Current income documentation: pay stubs from the last six months, employer letter, and contracts.
• Proof of the sponsor’s status: U.S. passport, certificate of naturalization, or green card.
• Bank statements and appraisals when assets are used to supplement insufficient income.

When the Obligation Ends

The I-864 contract does not expire automatically. Under INA 213A(a)(2), the sponsor’s obligation remains active until one of the following events occurs:

• The immigrant becomes a naturalized U.S. citizen.
• The immigrant completes 40 qualifying work quarters as computed by the Social Security Administration.
• The immigrant loses lawful permanent resident status and leaves the United States.
• The immigrant is subject to removal and obtains a new green card through another petition with a new I-864.
• The immigrant dies.

Divorce does not end the financial obligation. Sponsors who sign the I-864 for a spouse need to understand that the contract survives the marriage.

Errors That Sink Cases

Recurring defects that generate RFE, NOID, or outright denial:

• Using the prior year’s poverty guidelines table in a petition evaluated after the I-864P update.
• Forgetting to include the immigrant in the household size count.
• Attaching only the W-2 without the complete Form 1040.
• Listing high self-employment income without a Schedule C or proof of continuity.
• Sponsor with income at the edge of the minimum and no backup joint sponsor.
• Incorrect conversion of assets to income equivalent.
• Missing I-864A when the sponsor’s spouse’s income was counted.
• Sponsor receiving a means-tested public benefit without adjusting the calculation.

Strategies for Borderline Income Cases

When the sponsor does not comfortably meet the 125%, it is worth considering combinations before submitting:

• Add a joint sponsor with substantial margin above the minimum, ideally above 150%.
• Include the sponsor’s spouse via I-864A.
• Demonstrate sufficient liquidatable assets to cover the gap, using the correct multiplier.
• Wait for the next tax filing if current income has risen materially relative to the base year.
• Document continuity of employment with an employer letter detailing the annualized salary.

Each path has trade-offs. Joint sponsors assume full responsibility for the period set by law, and not every willing family member understands the extent of the commitment. For this reason, briefing the co-sponsor in advance about the civil consequences of the I-864 is an essential part of case preparation.

I-864 Timeline in the Process

The submission timing varies depending on the route:

• Consular processing: the I-864 is sent to the National Visa Center after the I-130 is approved, along with other civil and financial documents.
• Adjustment of status: the I-864 accompanies the I-485 package or is presented at the interview, per USCIS guidance.
• K-1 fiancé(e): the I-134 is used at the consulate for the K-1 visa; the I-864 only comes into play when the spouse files the I-485 after the marriage in the U.S.

The I-864 is reviewed again at any adjustment of status interview, and the officer may request proof of current income even if the form was previously accepted by the NVC.

Why the I-864 Deserves Careful Technical Attention

The Affidavit of Support is not accessory bureaucracy. When completed with a comfortable margin, consistent documents, and a correctly calculated household size, it neutralizes one of the most common friction points in the family process. When submitted at the edge of the minimum, with missing schedules or a poorly chosen joint sponsor, it becomes the primary reason for delay or denial in cases that would otherwise be approvable.
