Affidavit of Support (Form I-864): A Simple Reference Guide

One of the key aspects of obtaining a green card through family sponsorship (and certain employment categories) is ensuring that the foreign national will have adequate financial support in the United States. That’s where the Affidavit of Support (Form I-864) comes in. This legally binding document creates a contract between the sponsor (often a U.S. citizen or lawful permanent resident) and the U.S. government, guaranteeing the sponsored immigrant won’t become a public charge.

Whether you’re sponsoring a spouse, child, parent, or certain employment-based immigrants, understanding how to correctly complete and file Form I-864 is essential. This master page covers eligibility criteria, household size calculations, income thresholds, and the long-term responsibilities that sponsors must accept.

#What Is the Affidavit of Support (Form I-864)?

In family-based green card cases—and some employment-based cases where a family member has an ownership interest—Form I-864 is used to prove that the sponsor (petitioner) can financially support the intending immigrant at 125% of the Federal Poverty Guidelines (100% if the sponsor is an active-duty military member sponsoring a spouse).

#Why It Matters

The U.S. government requires this form to ensure that foreign nationals won’t rely on taxpayer-funded benefits. By signing Form I-864, the sponsor takes on a legal obligation to repay the government if certain means-tested public benefits are ever used by the sponsored immigrant.

#Who Must File Form I-864?

In most family-based green card cases, the petitioner is required to file Form I-864. Examples include:

• Spouse Sponsorship (U.S. citizen or LPR sponsoring a foreign spouse)
• Parent-Child Sponsorship
• Sibling Sponsorship
• Fiancé(e) to Marriage-Based Green Card (After the fiancé(e) enters on a K-1 and files for Adjustment of Status)

Certain employment-based petitions also trigger the Affidavit of Support if the petitioner (or a close relative of the petitioner) holds a significant ownership interest in the sponsoring company.

#Joint Sponsors & Household Members

#Joint Sponsors

If the primary sponsor (petitioner) doesn’t meet the income requirement, a joint sponsor can help. The joint sponsor must:

• Be a U.S. citizen or lawful permanent resident.
• Be domiciled in the United States.
• Meet the 125% of Federal Poverty Guidelines based on their own household size, plus all immigrants they are sponsoring.

Joint sponsors are equally liable if the sponsored immigrant receives certain public benefits. They sign a separate I-864, pledging their own financial resources to support the immigrant.

Important: The Affidavit of Support is a legally enforceable contract. If the sponsored immigrant receives means-tested public benefits, the government can sue the sponsor or joint sponsor to recover those costs. This obligation lasts until the immigrant becomes a U.S. citizen or earns 40 qualifying work quarters.

#Household Members (Form I-864A)

Sometimes a household member (e.g., adult child, parent, sibling living in the same residence) may contribute income to help the sponsor meet the threshold. In these cases, the household member completes Form I-864A, contracting to combine their income or assets with the primary sponsor’s.

#Income Requirements & Financial Eligibility

To evaluate financial eligibility, USCIS or the consulate compares the sponsor’s total household income to 125% of the Federal Poverty Guidelines (or 100% for active-duty military sponsors of a spouse/child). These guidelines are updated annually.

#Calculating Household Size

Count the following individuals:

1. You (the sponsor).
2. Any dependents you claim on your federal tax return (children, elderly parents).
3. The intending immigrant(s)—each person you’re sponsoring in this petition.
4. Any previously sponsored immigrants you’re still financially responsible for.

If your total household size is, for example, five, you’ll look at the poverty guideline for a five-person household. If your household size is borderline or you’re just above the guideline, you might:

• Demonstrate additional assets (real estate, investment accounts, etc.).
• Seek a joint sponsor to bolster your application.

#Sources of Income & Assets

#Acceptable Income

USCIS generally looks for stable, recurring income. Examples include:

• Salary or wages from full-time or part-time employment.
• Self-employment income, substantiated by tax returns and bank statements.
• Social Security, retirement, or disability benefits.
• Alimony or child support payments received.

#Using Assets

If your income alone doesn’t meet the 125% requirement, you can use assets to make up the shortfall. Qualifying assets must be:

• Liquid or easily convertible to cash within one year (e.g., savings accounts, stocks, mutual funds).
• Valued at five times the difference between your income and the required threshold (three times for spouses and children of U.S. citizens).

For instance, if you’re $10,000 short of the income requirement, you typically need assets worth $50,000 to compensate.

Did You Know: If you are sponsoring your spouse or minor child, assets only need to be valued at three times the income shortfall — not the standard five times required for other family relationships. This lower threshold makes it significantly easier to qualify using assets.

#Which Version of Form I-864 Do You Need?

There are multiple variants:

1. Form I-864 (Long Form): The standard Affidavit of Support used in most cases.
2. Form I-864EZ: For sponsors who meet specific criteria, including using only W-2 employment income for a single beneficiary.
3. Form I-864A: Used by household members who are pooling their income or assets with the sponsor.
4. Form I-864W: A waiver of the support requirement, applicable in limited cases (e.g., those with 40 quarters of credited work in the U.S. or certain children of U.S. citizens).

Most sponsors will use the standard Form I-864. Always check USCIS instructions to ensure you’re filing the correct version.

#Filing Form I-864: Step-by-Step

Accurate, thorough preparation can prevent Requests for Evidence (RFEs) and slowdowns.

1. Sponsor’s Basic Info
   • Full name, mailing address, and physical address.
   • Details of your U.S. citizenship or permanent resident status.
2. Immigrant(s) Being Sponsored
   • Name and date of birth of the beneficiary (or beneficiaries).
   • Relationship to the sponsor.
3. Household Size Calculation
   • List your spouse, children, other dependents, and any immigrants previously sponsored.
4. Current Income
   • Show your annual income from your most recent tax return.
   • If you have changed jobs, include an employment verification letter plus recent pay stubs.
5. Tax Information
   • Provide copies or transcripts of your most recent federal tax return.
   • Some cases may require the last three years’ returns, though the most recent is the primary focus.

For a detailed walkthrough on obtaining IRS tax return transcripts and understanding exactly which tax documents USCIS expects, see our guide to tax return requirements for immigration.

1. Assets (If Necessary)
   • Detail liquid assets (bank statements, mutual fund balances) or property valuations.
   • Provide evidence (e.g., property deeds, vehicle titles) and show how quickly they can be converted to cash.
2. Oath & Signature
   • Sign in blue or black ink if submitting a hard copy.
   • Ensure any joint sponsor or household member also completes their respective form and signatures.

Pro Tip: Consistency is key—your reported income should match your tax documents. If there’s a discrepancy (e.g., a new job with higher pay), attach an explanatory letter and verification from the new employer.

#Common Pitfalls & How to Avoid Them

1. Using Outdated Poverty Guidelines
   • Always check the current year’s figures. These typically update each spring.
2. Incorrect Household Count
   • Not including all dependents or missing previously sponsored immigrants can trigger an RFE.
3. Missing Documents
   • Failing to include W-2s, 1099s, or tax transcripts for your income claims.
   • Omitting valuations or proofs of ownership for assets.
4. Misunderstanding Domicile Requirements
   • Sponsors must generally reside in the United States or demonstrate an intent to re-establish domicile before the immigrant arrives.
5. Underestimating Liability
   • Some sponsors aren’t fully aware that their commitment can last until the sponsored immigrant becomes a U.S. citizen or has 40 quarters of work (among other termination events).

Warning: Divorce does not end your I-864 obligation. Even if you and the sponsored immigrant divorce, you remain financially responsible until one of the termination events occurs — such as the immigrant naturalizing or earning 40 work quarters. Courts have enforced this obligation in numerous cases.

#How USCIS & Consulates Evaluate the Affidavit of Support

#Adjustment of Status (Within the U.S.)

• USCIS reviews Form I-864 along with the I-485 (Application to Adjust Status).
• Officers may issue RFEs if income details are unclear or new.
• You might need to bring updated pay stubs or letters to your green card interview if your financial situation changed after filing.

#Consular Processing (Abroad)

• The National Visa Center (NVC) initially reviews Form I-864.
• Once your documents are “documentarily qualified,” your case moves to the U.S. Embassy/Consulate for the visa interview.
• The consular officer can request more information if they doubt your financial capability.

If the sponsor doesn’t meet the requirements—and no joint sponsor or household member can help—the immigrant’s visa or green card application may be denied on public charge grounds.

#Sponsor Obligations & Termination Events

When you sign Form I-864, you agree to support the immigrant so they do not become reliant on certain means-tested benefits. This obligation can last well beyond the green card’s issuance. It terminates only when:

1. The sponsored immigrant becomes a U.S. citizen.
2. The sponsored immigrant has earned 40 qualifying quarters (about 10 years of work) under the Social Security system.
3. The sponsored immigrant leaves the U.S. permanently or otherwise loses legal permanent resident status.
4. Either the sponsor or the immigrant dies.
5. A rescission of the affidavit is approved before the immigrant becomes a permanent resident (rare).

During that time, if the sponsored immigrant utilizes certain federal or state means-tested public benefits, the sponsor can be required to repay the cost of those benefits to the government.

The I-864 is required in both Adjustment of Status and Consular Processing cases. For the full marriage-based green card process, see our Marriage-Based Green Card service page.
