USCIS Form I-864: Everything You Need to Know

Are you sponsoring a family member for a green card and wondering what USCIS Form I-864 actually requires from you?

Form I-864, Affidavit of Support, is one of the most important financial documents in the family-based immigration process. By signing it, a sponsor agrees to take legal responsibility for financially supporting the intending immigrant. If the form is incomplete, inaccurate, or missing required documents, it can lead to delays, Requests for Evidence, or even denial of the application.

Because Form I-864 creates a legally binding obligation, it is essential to understand exactly what USCIS expects. Sponsors must meet specific income thresholds, calculate household size correctly, and provide detailed supporting documentation such as tax returns and proof of status. In some cases, a joint sponsor, assets, or additional forms may be required. Any non-English documents must also include certified English translations to avoid processing issues.

In this guide, we walk through who must file Form I-864, the financial requirements, required supporting documents, filing fees, how and where to submit the form, and how certified translations fit into the process. If you need translated documents for your application, we can also help make sure they meet USCIS requirements.

What Is USCIS Form I-864?

USCIS Form I-864, also called the Affidavit of Support, is a required document in most family-based green card cases. The purpose of Form I-864 is to show that the immigrant will have adequate financial support in the United States and is unlikely to become a public charge.

In simple terms, a public charge is someone who depends primarily on government assistance for basic living expenses. Through the I-864 process, the government requires a qualified sponsor to accept financial responsibility for the intending immigrant.

The I-864 is not just a form. It is a legally binding contract between the sponsor and the U.S. government. By signing Form I-864, the sponsor agrees to provide financial support to the immigrant if necessary. This obligation is enforceable by law, meaning the sponsored immigrant or even a government agency can take legal action if the sponsor fails to meet these responsibilities.

To qualify, the sponsor must generally demonstrate income at or above 125% of the Federal Poverty Guidelines for the correct household size. If the sponsor is on active duty in the U.S. Armed Forces and sponsoring a spouse or child, the requirement is reduced to 100% of the Federal Poverty Guidelines.

The financial obligation under Form I-864 does not last forever, but it is long-term. It typically ends only when one of the following occurs:

• The immigrant becomes a U.S. citizen
• The immigrant earns 40 qualifying quarters of work, which is usually about 10 years
• The immigrant permanently leaves the United States
• The immigrant dies

Divorce or separation does not automatically end the sponsor's responsibility. That is why understanding the seriousness of the I-864 before signing is so important.

Who Needs to File Form I-864?

Not every immigrant visa case requires Form I-864, but most family-based green card applications do. Understanding whether the affidavit applies to your situation is a critical first step.

Immigration Categories That Require Form I-864

Form I-864 is generally required for:

• Immediate relatives of U.S. citizens, including spouses, unmarried children under 21, and parents of U.S. citizens who are 21 or older
• Family preference immigrants, such as unmarried sons and daughters of U.S. citizens, spouses and unmarried children of lawful permanent residents, married sons and daughters of U.S. citizens, and siblings of U.S. citizens who are 21 or older
• Certain employment-based immigrants, but only when a U.S. citizen, lawful permanent resident, or U.S. national relative filed the immigrant petition, or a relative owns at least 5% of the business that filed it

In family-based immigration, the petitioner is generally required to submit an affidavit of support even if a joint sponsor is later needed because the petitioner's income is not enough on its own.

Who Can Be a Sponsor?

To file this sponsor form with USCIS, the sponsor must:

• Be at least 18 years old
• Be a U.S. citizen, U.S. national, or lawful permanent resident
• Be domiciled in the United States

Being domiciled in the United States means the sponsor's principal residence is in the U.S. and they intend to maintain it. Evidence can include a U.S. address, tax filings, employment in the U.S., voting records, or property ownership.

Petitioner vs. Joint Sponsor vs. Substitute Sponsor

It is important to distinguish between different types of sponsors under the I-864 process:

• Petitioner: The person who filed the immigrant petition, such as Form I-130. In most family-based cases, the petitioner must file Form I-864.
• Joint sponsor: If the petitioner's income does not meet the required threshold, a joint sponsor may file a separate Form I-864. A joint sponsor must independently meet all financial and eligibility requirements.
• Substitute sponsor: If the original petitioner dies after petition approval but before permanent residence is granted, a qualified close relative may step in as a substitute sponsor and submit Form I-864.

Who Is Exempt and May Use Form I-864W?

Some immigrants do not submit Form I-864 at all and instead use Form I-864W to claim an exemption where applicable.

Examples include applicants who:

• Have earned or can be credited with 40 qualifying quarters of work
• Are under 18, unmarried, immigrating as the child of a U.S. citizen, and will automatically become a U.S. citizen after admission under the Child Citizenship Act
• Are applying as a self-petitioning battered spouse or child
• Are applying as the self-petitioning widow or widower of a U.S. citizen

Because the exemption rules are category-specific, you should confirm the correct form before filing.

Quick Comparison Table

I-864 Financial Requirements (Income, Assets, and Household Size)

One of the most important parts of Form I-864 is proving that the sponsor meets the minimum income requirement.

The 125% Poverty Guideline Rule

In most cases, the sponsor must show income equal to at least 125% of the Federal Poverty Guidelines for their household size. The exact dollar amount changes over time and depends on how many people are included in the household calculation.

There is one key exception. If the sponsor is on active duty in the U.S. Armed Forces and is sponsoring a spouse or unmarried child, the requirement is reduced to 100% of the Federal Poverty Guidelines.

How to Calculate Household Size

Household size is not just the sponsor and the immigrant. It generally includes:

• The sponsor
• The sponsor's spouse
• Dependent children
• Any other dependents listed on the sponsor's tax return
• Any immigrants previously sponsored under Form I-864 if the obligation is still active
• The intending immigrant or immigrants being sponsored now

Getting this number right is critical because it directly affects the income threshold under the I-864 rules.

Tax Returns and Proof of Income

Sponsors must typically submit a copy of their most recent federal income tax return. They may also include IRS tax transcripts and, if helpful, returns from the past three years. If submitting a photocopy of a tax return, include associated W-2s or 1099s unless you are using an IRS transcript.

In addition to past tax documents, USCIS or NVC may expect proof of current income, such as recent pay stubs or an employment letter.

Using Assets to Qualify

If income alone is not enough, assets may be used to meet the Form I-864 requirement.

Qualifying assets can include:

• Bank accounts
• Real estate
• Stocks and bonds
• Other investments

Assets must be convertible to cash within one year without causing significant hardship. The sponsor must provide evidence of ownership, the asset's location, date of acquisition, and current market value. For real estate, this includes a recent appraisal and information about any mortgages or liens.

In most cases, the total value of assets must equal at least five times the difference between the sponsor's income and the required guideline amount. When sponsoring a spouse or child, the requirement is generally reduced to three times the difference.

Using Household Member Income: Form I-864A

A sponsor may also rely on the income or assets of certain household members. In that case, the household member must complete and sign Form I-864A, Contract Between Sponsor and Household Member, and provide supporting financial documentation.

What Counts Toward the I-864 Financial Requirement

• Sponsor's income: Current individual annual income supported by tax returns and proof of employment
• Household member income: Income from qualifying household members who sign Form I-864A and provide documentation
• Immigrant's income: If the intending immigrant is already authorized to work and the income will continue from the same source after obtaining permanent residence
• Qualifying assets: Cash, savings, real estate equity, and investments that meet documentation and valuation requirements

Understanding how income, assets, and household size interact under Form I-864 can help prevent delays and reduce the risk of a Request for Evidence.

GET THE FILE

Submitting Form I-864 without proper documentation is one of the most common reasons for delays. Whether you complete the form using the official PDF or through a recent USCIS download, you must include clear supporting evidence.

Below is a practical checklist to help you organize your Form I-864 package.

Federal Income Tax Documents

• A copy of your most recent federal individual income tax return, usually Form 1040
• Copies of associated W-2s and 1099s if submitting a photocopy of your return
• Alternatively, an IRS tax transcript, which generally removes the need to include W-2s or 1099s
• Tax returns or transcripts from the past three years if they help clarify the financial picture, though the most recent year is typically the core requirement

Foreign tax returns are generally not required unless you were not required to file a U.S. federal return and need to document income earned abroad.

Proof of Current Income

USCIS and NVC look at both past and current income. Include:

• Recent pay stubs
• An employment verification letter stating your position, salary, and employment status
• Evidence of any other ongoing income you are relying on

Proof of U.S. Citizenship or Lawful Permanent Residence

Provide a copy of one of the following:

• U.S. passport
• U.S. birth certificate
• Certificate of Naturalization or Certificate of Citizenship
• Permanent Resident Card, Form I-551

Asset Documentation (If Needed)

If you are using assets to qualify, include:

• Bank statements
• Real estate appraisals
• Documentation of stocks, bonds, or other investments
• Evidence of ownership, current value, and any liens or mortgages

Form I-864A (If Using Household Member Income)

If relying on a household member's income or assets, include:

• A completed and signed Form I-864A
• Supporting financial documents for that household member
• Proof of the relationship to the sponsor

Carefully reviewing this checklist before submitting Form I-864 can help reduce the risk of a Request for Evidence.

Where to Submit Form I-864

Where you submit Form I-864 depends on the immigrant's process:

• Adjustment of status inside the United States: Submit the form to USCIS, typically together with Form I-485 or as instructed by USCIS
• Consular processing outside the United States: Submit the form through the Department of State, usually by uploading the signed form and financial evidence through the National Visa Center's CEAC system, following the case-specific instructions

Always verify the correct filing location and instructions on the official USCIS or Department of State website before sending your documents.

How to Complete and Submit Form I-864

Completing Form I-864 correctly is essential to avoid delays or Requests for Evidence. Below is a simplified step-by-step overview to help you move through the process confidently.

Step 1: Download the Correct Version

Start by visiting the official USCIS website to access the most recent Form I-864 download. You can download the current PDF directly from USCIS. Always make sure you are using the latest edition listed on the USCIS page, because outdated versions may be rejected.

Step 2: Complete the Form in English

Form I-864 must be completed in English. You may type your answers into the PDF or print the form and complete it neatly in black ink if you are preparing it by hand.

The form is organized into clear sections. In general, you will complete:

• Part 1: Basis for filing, such as whether you are the petitioner, joint sponsor, or substitute sponsor
• Part 2: Information about the principal immigrant
• Part 3: Information about additional immigrants, if applicable
• Part 4: Sponsor's personal details
• Part 5: Household size calculation
• Part 6: Employment and income information
• Part 7: Assets, if needed
• Part 8: Sponsor's declaration and signature

Take your time when calculating household size and entering income figures. These numbers directly affect whether you meet the financial requirements.

Step 3: Gather and Attach Supporting Documents

Before submitting, attach all required supporting documents, such as:

• Your most recent federal tax return or IRS transcript
• W-2s or 1099s, if required
• Proof of current income
• Proof of U.S. citizenship or lawful permanent residence
• Asset documentation, if using assets
• Form I-864A, if relying on household member income

Organize the documents clearly to make review easier.

Step 4: Sign the Form Properly

USCIS requires a valid signature. A typed name, signature stamp, or auto-generated signature is not acceptable. Under USCIS signature policy, a copied or scanned version of an original handwritten signature is generally acceptable for paper filings unless the form instructions say otherwise.

Before you submit anything, make sure the signature is valid, consistent with the sponsor's name on the form, and placed in the correct signature section. If your case is going through NVC, you will typically upload a scan of the signed form and supporting documents through CEAC. Unsigned or improperly signed forms can be rejected.

Step 5: Submit the Form to the Correct Address

Form I-864 is not a standalone USCIS online filing. How you submit it depends on the case path.

Where you send it depends on the type of case:

• If the immigrant is applying for adjustment of status in the United States, submit it to USCIS, usually together with Form I-485 or as instructed
• If the immigrant is going through consular processing, follow the Department of State or National Visa Center instructions, which usually involve CEAC document upload

Always verify the correct filing address on the official USCIS website before mailing your package, because addresses vary by case type and can change.

Once submitted, keep copies of everything for your records. Careful preparation at this stage can help make sure your Form I-864 moves through the process more smoothly.

Form I-864 Filing Fee and Affidavit of Support Fee Explained

Questions about the I-864 filing fee are common, especially because different government agencies are involved in the green card process. Let's clarify exactly when a fee applies and when it does not.

Is There an I-864 Filing Fee?

If you are submitting Form I-864 to USCIS as part of an adjustment of status application, there is no separate USCIS filing fee for Form I-864 itself.

In most family-based cases inside the United States, Form I-864 is filed together with Form I-485 or after Form I-130 approval, depending on the process. When submitted to USCIS in that context, there is no standalone affidavit of support fee required specifically for the form itself.

However, that does not mean the entire immigration process is free. Other forms, such as Form I-485 or Form I-130, have their own filing fees.

If the case is handled through consular processing outside the United States, the situation is different. When the affidavit of support is processed through the Department of State, such as via the National Visa Center, the Department of State currently lists an Affidavit of Support Review fee of $120 for cases where that review fee applies.

Because government filing fees can change, always confirm the most current information on the official USCIS or Department of State website before submitting payment.

In summary:

• USCIS filing inside the U.S.: No separate Form I-864 filing fee
• Department of State consular processing: An affidavit of support review fee may apply

Understanding when an I-864 fee applies can help you avoid confusion and unnecessary payments.

How to Withdraw Form I-864

Circumstances can change after you submit Form I-864. A sponsor may decide they no longer wish to continue with the affidavit of support, but timing is critical.

A sponsor, joint sponsor, or substitute sponsor can withdraw an I-864 only if the request is made in writing and received before the immigrant visa is issued or before USCIS approves the green card application.

When Withdrawal Is Still Possible

You may withdraw the affidavit of support if:

• The immigrant is going through consular processing and the visa has not yet been issued
• The immigrant has applied for adjustment of status, and USCIS has not yet approved the green card

To do this, you must send a signed written statement to the office currently handling the case. This may be USCIS, the National Visa Center, or a U.S. embassy or consulate, depending on where the application is pending. The letter should clearly state that you wish to withdraw your Form I-864 and include identifying information such as the sponsor's name and the immigrant's case details.

When It Is Too Late to Withdraw

Once the immigrant becomes a lawful permanent resident, either by entering the United States with an immigrant visa or by having adjustment of status approved, the affidavit of support generally cannot be withdrawn.

At that point, the I-864 becomes a fully enforceable contract. The sponsor's financial obligation continues until one of the legally defined end events occurs, such as the immigrant becoming a U.S. citizen or earning 40 qualifying quarters of work. Withdrawal is typically only possible if the underlying immigrant petition itself is successfully withdrawn before permanent residence is granted.

Because of the long-term legal consequences, sponsors should fully understand their responsibilities before signing Form I-864.

MotaWord's Certified Translations for I-864 Supporting Documents

If any of your supporting documents are not in English, USCIS requires that you submit a complete certified English translation along with the original document.

This rule applies to all documents submitted with Form I-864, including foreign tax records, birth certificates, marriage certificates, or other civil documents. Failing to include a proper certified translation for USCIS can lead to delays, a Request for Evidence, or even denial if the officer cannot review the document properly.

Because Form I-864 involves financial evidence and legal responsibility, accuracy is critical. Any inconsistencies between the original document and the English translation may raise questions or slow down your case. Proper I-864 document translation helps make sure USCIS can clearly review income, assets, and supporting civil records without confusion.

If you need a certified translation for USCIS, we provide USCIS-compliant certified translation services with fast turnaround times and clear formatting.

Frequently Asked Questions About Form I-864

Below are clear, concise answers to some of the most common high-intent questions about Form I-864 and how it works in real cases.

Is Form I-864 required for Form I-485?

In most family-based adjustment of status cases, yes. If the immigrant is filing Form I-485 to apply for a green card inside the United States, Form I-864 is usually required to show that they have adequate financial support.

There are limited exceptions, such as categories of immigrants who are exempt from the affidavit of support requirement and may instead use Form I-864W. However, for immediate relatives and most family preference categories, the I-864 must be submitted either together with Form I-485 or when requested by USCIS.

What is the difference between Form I-864 and I-864EZ?

Form I-864 is the standard full version of the affidavit of support. It is used in most cases, especially when the sponsor is sponsoring more than one immigrant, is self-employed, needs to use assets, or when a joint sponsor is involved.

Form I-864EZ is a simplified version. It may only be used if:

• The sponsor is sponsoring just one immigrant
• The sponsor qualifies based only on salary or pension income shown on a Form W-2
• The sponsor is not using assets
• No joint sponsor is required

Even though I-864EZ is shorter, it creates the same legally binding financial obligation as the regular I-864.

What is the difference between Form I-864 and I-134?

Form I-864 is a legally enforceable contract used in permanent immigration cases. By signing it, the sponsor agrees to financially support the immigrant and may be sued by the immigrant or a government agency if they fail to do so.

Form I-134, on the other hand, is generally used for temporary visa situations. It is not treated the same way as the I-864 for permanent residence cases. Family and certain employment immigration cases typically use Form I-864, while other short-term situations may use Form I-134 instead.

How long is Form I-864 valid?

The obligations under Form I-864 do not expire after a set number of years. Instead, they continue until one of the following occurs:

• The immigrant becomes a U.S. citizen
• The immigrant earns 40 qualifying quarters of work
• The immigrant permanently leaves the United States
• The immigrant dies

Divorce does not end the sponsor's responsibility. This long-term commitment is one of the most important aspects of signing Form I-864.

Can multiple sponsors file Form I-864?

Yes. If the primary sponsor does not meet the income requirement, a joint sponsor may submit a separate Form I-864.

Each sponsor must independently meet the financial threshold for their household size and must qualify under the same eligibility rules. When multiple sponsors are involved, each affidavit creates a separate legally binding obligation.

Final Thoughts on USCIS Form I-864

Form I-864 is more than just another immigration form. It is a legally binding financial commitment that can last for years. Careful preparation today can make your immigration journey smoother tomorrow.

Before submitting Form I-864, carefully review the official USCIS instructions and confirm that you are using the most current version of the form. Make sure your income calculations are consistent with your tax documents and that any assets are properly documented. Small mistakes can slow down an otherwise strong case.

If your application includes documents in a language other than English, remember that USCIS requires complete certified translations. Working with a professional provider like MotaWord can help make sure your translations meet USCIS standards and avoid unnecessary complications.
