Introduction

If you are sponsoring a family member for a green card, there is one document that stands between your relative and lawful permanent residence: Form I-864, Affidavit of Support Under Section 213A of the INA.

This form is not a simple declaration of intent. It is a legally enforceable contract between you — the sponsor — and the U.S. government. By signing it, you are promising that the person you are sponsoring will not become financially dependent on public assistance programs. That obligation can last for years, sometimes decades, and carries real financial consequences if it is not honored.

Understanding the I-864 affidavit of support requirements before you begin can save you time, prevent costly errors, and keep your relative's immigration case on track. This guide covers everything: who must file, who qualifies as a sponsor, what income thresholds apply, which documents to gather, and how to complete each section of the form correctly.

What Is Form I-864 Affidavit of Support?

Form I-864, officially titled Affidavit of Support Under Section 213A of the INA, is a contract between a U.S. citizen or lawful permanent resident (the sponsor) and the U.S. government. By completing and signing the form, the sponsor agrees to use their financial resources to support the intending immigrant if that becomes necessary.

The legal foundation for this requirement comes from Sections 212(a)(4) and 213A of the Immigration and Nationality Act (INA), codified at 8 CFR 213a. Its primary purpose is to prevent sponsored immigrants from relying on means-tested public benefits — a concept formally known as the public charge ground of inadmissibility.

When a sponsor signs Form I-864, USCIS (or the U.S. Department of State during consular processing) treats the sponsor's income and assets as available to the sponsored immigrant when evaluating eligibility for public programs. If the immigrant does receive means-tested benefits, the agency that provided those benefits can seek reimbursement directly from the sponsor. Sponsors who fail to repay can be sued and held liable for the costs of the benefits, legal fees, and related expenses.

This is not a formality. It is a serious financial commitment that every sponsor should fully understand before signing.

I-864, I-864EZ, and I-864A: What Is the Difference?

There are three related forms in the affidavit of support family:

Form I-864 — The standard affidavit of support. Required in almost all family-based immigration cases and certain employment-based cases where the petitioner has a familial relationship to the immigrant.
Form I-864EZ — A simplified version available only when the sponsor is the petitioner, is sponsoring only one immigrant, and is relying solely on their own income (wages or salary) shown on their most recent federal tax return. It cannot be used when household member income or assets are needed to qualify.
Form I-864A, Contract Between Sponsor and Household Member — A supplemental form used when the primary sponsor needs to add the income of a household member (such as a spouse or adult relative living in the home) in order to meet the required income threshold.

In the vast majority of cases, sponsors will complete Form I-864. The simplified I-864EZ is only appropriate in a narrow set of circumstances.

Who Must File Form I-864?

Not every immigrant needs an affidavit of support, but most family-based immigrants do. Under U.S. immigration law, Form I-864 is required for:

1. All immediate relatives of U.S. citizens, including:

Spouses of U.S. citizens
Unmarried children under 21 years of age of U.S. citizens
Parents of U.S. citizens (when the U.S. citizen is at least 21 years old)

2. All family-based preference immigrants, including:

Unmarried adult sons and daughters of U.S. citizens (F1 category)
Spouses and unmarried sons and daughters of lawful permanent residents (F2A and F2B)
Married sons and daughters of U.S. citizens (F3)
Brothers and sisters of U.S. citizens (F4 — but only when the sibling petitioning is a U.S. citizen)

3. Certain employment-based preference immigrants where the petitioner (employer or business owner) has a familial relationship to the immigrant beneficiary.

Exceptions: Who Does NOT Need to File Form I-864?

The following categories of intending immigrants are generally not required to submit Form I-864:

Immigrants who have already earned, or can be credited with, 40 qualifying quarters (credits) of work in the United States (roughly 10 years of Social Security-covered work)
Certain children who will automatically acquire U.S. citizenship upon admission
Employment-based immigrants (first, second, or third preference categories) where the I-140 petitioner is not a relative and has no significant ownership interest in the sponsoring business
Immigrants applying under specific humanitarian categories that are exempt from the public charge requirement (such as refugees, asylees, and certain special immigrant categories)

If you are unsure whether Form I-864 is required in your case, consulting with a qualified immigration attorney is always a good idea before proceeding.

Who Can Be a Sponsor?

Every Form I-864 case has at least one sponsor — the primary petitioner. Some cases also involve a joint sponsor or household member. Understanding the roles clearly is essential because different situations call for different forms and documentation.

The Primary Petitioner Sponsor

The primary sponsor is the person who filed (or is filing) the immigrant petition — typically Form I-130 for family-based cases or Form I-129F for a fiancé(e). Even if the primary sponsor's income is zero or falls below the required threshold, they must still file Form I-864. They cannot simply opt out.

To be a valid sponsor, the primary petitioner must:

Be a U.S. citizen, U.S. national, or lawful permanent resident
Be at least 18 years of age
Be domiciled (have their primary home) in the United States or a U.S. territory

The Joint Sponsor

When the primary sponsor's income does not meet the 125% federal poverty guideline threshold, a joint sponsor can step in. A joint sponsor takes on independent legal responsibility for supporting the intending immigrant — they are not merely "helping" the primary sponsor. This means:

The joint sponsor must meet the full income requirement on their own (they cannot combine income with the primary sponsor)
The joint sponsor must file their own separate Form I-864
The joint sponsor must be a U.S. citizen, national, or lawful permanent resident, at least 18 years old, and domiciled in the United States

A joint sponsor can be any qualifying person — a friend, relative, employer, or community member. There is no requirement that the joint sponsor be related to the immigrant.

Household Members (Form I-864A)

A household member is someone who lives in the sponsor's home and is willing to pool their income with the sponsor's to meet the income requirement. This is different from a joint sponsor because:

The household member's income is combined with the primary sponsor's income
The household member must sign Form I-864A, agreeing to make their income available to the sponsored immigrant
The household member must be listed as a dependent on the sponsor's most recent federal tax return, OR be the intending immigrant, OR be related to the sponsor and actually live in the sponsor's home

Common examples include a working spouse, an adult child living at home, or a sibling sharing the household.

Substitute Sponsor

If the original petitioner dies after an immigrant petition has been approved but before the immigrant obtains lawful permanent residence, a substitute sponsor may step in. The substitute sponsor must:

Be related to the intending immigrant (spouse, parent, mother/father-in-law, sibling, adult child 18+, son/daughter-in-law, grandparent, grandchild, or legal guardian)
Be a U.S. citizen, national, or lawful permanent resident
Meet all other sponsor requirements

The substitute sponsor assumes all the obligations of an original I-864 sponsor.

I-864 Income Requirements: How Much Do You Need to Earn?

This is often the most stressful part of the process. The income requirement is based on the Federal Poverty Guidelines, updated each year by the U.S. Department of Health and Human Services and published by USCIS as Form I-864P.

The 125% Rule

Most sponsors must demonstrate income at or above 125% of the Federal Poverty Guidelines for their household size. The only exception is active-duty members of the U.S. Armed Forces or U.S. Coast Guard sponsoring a spouse or child — they qualify at 100% of the poverty guidelines.

As a concrete example: for 2024, the minimum income requirement for a sponsor in the 48 contiguous states sponsoring one immigrant (household size of 2) was approximately $25,550 per year.

The threshold increases with each additional person in the household. For a household of five, the requirement would be significantly higher. Always check the most current USCIS I-864P poverty guidelines chart at the time of filing.

How to Calculate Household Size

Household size for Form I-864 is not simply the number of people physically living in your home. It must be calculated using a specific formula that includes:

The sponsor themselves (always counted as 1)
The sponsor's spouse (if married)
The sponsor's children under 21 who are unmarried and living with the sponsor
Anyone the sponsor has previously sponsored on Form I-864 or I-864EZ who has not yet become a U.S. citizen or earned 40 qualifying quarters of work
The intending immigrant(s) being sponsored in this affidavit
Any dependents claimed on the sponsor's most recent federal income tax return

People who merely share a house but are not dependents are not automatically counted. Accuracy in this calculation is critical — an error here can affect whether the sponsor qualifies.

What Counts as Income?

USCIS considers current annual income, not just historical tax return figures. Income types that qualify include:

Wages and salaries from employment
Self-employment income (net, after business expenses)
Dividends, interest, and rental income
Pension and retirement income
Alimony and child support received
Military allowances and benefits

Income types that generally do not count include unemployment benefits, most public assistance payments, and one-time income sources.

USCIS will primarily evaluate current income — so a sponsor who recently got a higher-paying job can submit an employment letter showing their current salary, even if their tax returns reflect lower prior-year income.

When Income Is Not Enough: Using Assets

If the sponsor's income falls short of the 125% poverty guideline threshold, assets can be used to make up the difference. USCIS allows sponsors to count assets such as:

Bank account balances (savings and checking)
Stocks, bonds, and mutual funds (at current market value)
Real estate equity (current market value minus outstanding mortgage debt)

The asset calculation rule: The total asset value must be worth five times the shortfall between the sponsor's income and the required poverty guideline amount. However, when the immigrant being sponsored is the spouse or child (18+) of a U.S. citizen, the required asset value drops to three times the shortfall.

Example: If the required income is $25,550 and the sponsor earns $22,000, the shortfall is $3,550. For most cases, the sponsor would need to show assets worth at least $17,750 (5 × $3,550). For a spouse or adult child of a U.S. citizen, the asset requirement drops to $10,650 (3 × $3,550).

Required Documents for Form I-864

Gathering the right documents before completing the form saves significant time and prevents avoidable delays. The following is a comprehensive document checklist for Form I-864.

Core Documents Every Sponsor Needs

Federal Income Tax Returns Submit copies of your federal income tax return for the most recent tax year. USCIS requires only the most recent year, but the form asks about the prior three years — it is recommended to provide returns for all three if they strengthen your case. Include all W-2s, 1099s, and relevant schedules. Self-employed sponsors should include IRS transcripts and Schedule C or K-1 forms.

If you were not required to file a tax return in a given year, you must provide a written explanation.

Employment Verification Letter A letter from your employer on company letterhead, signed by an HR representative or supervisor, stating your job title, start date, and your anticipated annual earnings. USCIS will compare this figure against the federal poverty guideline for your household size. The salary stated in this letter and the year-to-date total on your pay stubs should match.

Recent Pay Stubs Include your three most recent pay stubs. For direct deposit recipients, bank statements showing payroll deposits may be substituted or added for additional clarity. Self-employed individuals or gig workers should provide invoices and bank statements showing deposits.

Proof of U.S. Citizenship or Lawful Permanent Residence Every sponsor must document their immigration status:

U.S. citizens: passport, birth certificate, or naturalization certificate
Lawful permanent residents: copy of both sides of the permanent resident card (green card)

If Using Household Member Income: Form I-864A Each household member whose income will be counted must complete and sign a separate Form I-864A. Include with it their own tax returns, W-2s, and proof of relationship and residency in the sponsor's household.

If Using Assets Provide documentation of the current value of each asset: bank statements (most recent 12 months), brokerage account statements, real estate appraisals or assessed value documentation, and mortgage statements.

Step-by-Step: How to Fill Out Form I-864

Form I-864 must be typed or printed clearly in black ink. Do not leave any field blank — enter "N/A" where a question does not apply. Submit only photocopies of supporting documents; never send originals unless specifically requested.

Part 1: Basis for Filing Affidavit of Support

Select the box that describes your relationship to the immigrant and why you are filing:

Box 1.a — You are the petitioner who filed or is filing Form I-130, I-129F, I-600, or I-800 for the immigrant
Box 1.b — You filed Form I-140 (Immigrant Petition for Alien Worker) for an immigrant who is related to you as a family member
Box 1.c — You have at least 5% ownership interest in a business that filed Form I-140 for a family member
Box 1.d — You are the only joint sponsor
Box 1.e — You are the substitute sponsor because the original petitioner is deceased

Part 2: Information About the Principal Immigrant

Provide the full legal name, date of birth, country of birth, country of citizenship, U.S. Social Security Number (if applicable), and alien registration number (A-Number) of the primary immigrant you are sponsoring.

Part 3: Information About the Immigrants You Are Sponsoring

This section lists any additional family members (spouse and/or children) who will immigrate within six months of the principal immigrant. List their names, dates of birth, country of birth, and relationship to the principal immigrant.

Part 4: Information About You (The Sponsor)

Complete all personal information fields: full legal name, mailing address, date of birth, place of birth, Social Security Number (required — U.S. citizens and permanent residents must provide this), and immigration status. Indicate whether you are a U.S. citizen, U.S. national, or lawful permanent resident.

Part 5: Household Size

Calculate your household size following the rules described in the income requirements section above. Enter the total number and list each person included in the count. Accuracy here is essential — it determines whether you meet the income threshold.

Part 6: Sponsor's Employment and Income

Provide your current employment information: employer name, address, and your annual salary. Then enter your income for the most recent three tax years from your returns. If you are self-employed, describe your business and net income. Report total household income if you are combining income from household members (whose I-864A forms must be attached).

Part 7: Use of Assets to Supplement Income

Complete this section only if your income does not meet the 125% poverty guideline threshold and you need to count assets to make up the difference. Enter the value of savings/checking accounts, stocks and bonds, and real estate equity. Assets of the intending immigrant may also be included in certain circumstances.

Part 8: Sponsor's Contract, Statement, Contact Information, Certification, and Signature

This is the most important part of the form. Read it carefully. By signing here, you are entering into a legally binding contract with the U.S. government. You are certifying that all information is true and correct, and you are agreeing to financially support the immigrant if called upon to do so.

Do not leave this section unsigned. USCIS will reject any Form I-864 that lacks the sponsor's original signature. The date of signature must be within one year of the submission date.

Parts 9 and 10 collect information about any interpreter or preparer who helped complete the form. If you completed the form yourself without assistance, these sections can be marked accordingly.

When and How to Submit Form I-864

The timing and submission pathway for Form I-864 depends on where the immigration application is being processed.

Filing Through USCIS (Adjustment of Status — Form I-485)

If the intending immigrant is already in the United States and is applying to adjust status to lawful permanent resident using Form I-485, the completed and signed Form I-864 (and any required Form I-864A) is submitted together with Form I-485. The mailing address for Form I-485 depends on the immigrant's category and current filing location.

Filing Through the National Visa Center (Consular Processing)

When the intending immigrant will apply for an immigrant visa at a U.S. Embassy or Consulate overseas, the National Visa Center (NVC) will instruct the petitioner to submit the Form I-864 during the document collection phase. The most recent federal tax return, IRS tax transcripts, and W-2/1099 forms must also be submitted to the NVC.

Key Submission Rules

One-year validity: Form I-864 must be filed within one year of the sponsor's signature date. If more than 12 months pass between signature and submission, a new form with a fresh signature will be required.
Photocopies only: Unless USCIS or a consular officer specifically requests originals, submit copies only.
Do not include the USCIS checklist: The official checklist provided on the USCIS website is for your own preparation use only — do not submit it with the form.
Foreign-language documents: Any documents not in English must be accompanied by a certified English translation.

The Sponsor's Legal Obligations Under Form I-864

Understanding what you are agreeing to when you sign Form I-864 is as important as understanding how to complete the form.

How Long Does the Obligation Last?

The sponsor's obligation under Form I-864 is legally enforceable and continues until one of the following conditions is met:

The sponsored immigrant becomes a U.S. citizen
The sponsored immigrant is credited with 40 qualifying quarters of work in the United States (approximately 10 years)
The sponsored immigrant dies
The sponsored immigrant permanently departs the United States (and abandons lawful permanent resident status)
The sponsor dies — in this case, the obligation ends with the sponsor's death; the estate is not liable for ongoing support after death

Divorce does not end the obligation. If a sponsor divorces the immigrant they sponsored, they remain legally bound by Form I-864 until one of the qualifying conditions above is met.

What Happens If the Immigrant Receives Public Benefits?

If a sponsored immigrant receives designated federal, state, or local means-tested public benefits, the government agency that provided those benefits shall request reimbursement from the sponsor. If the sponsor does not repay, the agency may sue the sponsor in federal or state court. The sponsor may be held responsible for the cost of benefits paid, legal fees, and other related costs.

Not all public programs are considered means-tested for this purpose. Programs such as emergency Medicaid, school lunch programs, and immunization assistance are generally not included. Sponsors should review the current list of designated means-tested benefits on the USCIS website.

Common Mistakes to Avoid on Form I-864

Even small errors on Form I-864 can trigger a Request for Evidence (RFE), cause delays, or result in the form being rejected entirely. The following mistakes are among the most frequent — and the most avoidable.

Leaving fields blank. Every field on the form must be completed. If a question does not apply to your situation, write "N/A" rather than leaving it empty.

Forgetting to sign the form. USCIS will automatically reject any unsigned Form I-864. Check the signature and date fields in Part 8 before submitting.

Submitting outdated tax returns. Always use the most recent tax year's return. If the most recent year's return has not yet been filed by the time you submit, provide the prior year's return along with a brief explanation.

Miscalculating household size. Including too few people underestimates the income needed; including too many inflates it. Follow the specific USCIS formula precisely.

Inconsistent income figures. The annual salary on your employment letter should match the year-to-date figures on your pay stubs. Discrepancies raise red flags for USCIS reviewers.

Submitting original documents unnecessarily. Submit photocopies only. Originals submitted without being requested may be destroyed by USCIS upon receipt.

Not including all required household member forms. If you are using a household member's income, their completed and signed Form I-864A must accompany your I-864.

Filing an expired form. Always download the current version of Form I-864 from USCIS.gov. Outdated versions of the form will be rejected.

Frequently Asked Questions (FAQs)

Q1: What is the purpose of Form I-864? Form I-864 is a legally binding contract between a U.S. citizen or lawful permanent resident (the sponsor) and the U.S. government. By signing it, the sponsor promises to financially support the sponsored immigrant and prevent them from relying on means-tested public benefits.

Q2: How long is a sponsor financially responsible under Form I-864? The obligation lasts until the sponsored immigrant becomes a U.S. citizen, earns 40 qualifying quarters of U.S. work credits (roughly 10 years), permanently departs the United States, or dies. Divorce alone does not end the obligation.

Q3: What income is required for Form I-864? Most sponsors must show income at or above 125% of the federal poverty guidelines for their household size. Active-duty military members sponsoring a spouse or child qualify at 100%. The exact dollar amount changes each year — always check the current USCIS Form I-864P poverty guidelines chart.

Q4: Can I use a joint sponsor if I don't earn enough? Yes. A joint sponsor who meets the income requirements independently can file their own separate Form I-864 to supplement the primary petitioner's filing. The joint sponsor takes on the same legal obligations as the primary sponsor.

Q5: Can assets be used if my income is not high enough? Yes. If your income falls short of the required threshold, you can supplement it with liquid assets such as savings, stocks, bonds, and real estate equity. The total asset value must generally be worth five times the shortfall — or three times if the immigrant is the spouse or adult child of a U.S. citizen.

Q6: What documents do I need to submit with Form I-864? At minimum: your most recent federal income tax return with W-2s and 1099s, an employment verification letter on company letterhead, recent pay stubs, and proof of your U.S. citizenship or lawful permanent residence. If using household member income, include completed Form I-864A for each household member.

Q7: Does Form I-864 expire? The signed Form I-864 must be filed within one year of the sponsor's signature date. If more than 12 months pass between signature and submission, the sponsor must sign a new form.

Q8: Can the sponsored immigrant work to meet the income requirement? An intending immigrant's income can be counted in certain circumstances — primarily when their income will continue from the same source after immigration. However, they must complete Form I-864A only if their spouse and/or children are also immigrating with them.

Q9: What happens if I submit incorrect information on Form I-864? Submitting false or misleading information on Form I-864 is a federal offense. It can result in the denial of the immigration application, civil or criminal penalties for the sponsor, and potential bars to future immigration benefits.

Q10: Where do I submit Form I-864? The submission destination depends on where the immigrant is applying. For Adjustment of Status inside the U.S. (Form I-485), submit Form I-864 together with Form I-485 to USCIS. For consular processing abroad, submit the form to the National Visa Center as directed in their instructions.
