Affidavit of Support for Marriage - I-864 Guide (2026 Edition)

Applying for a marriage-based green card involves a lot of paperwork, but few forms cause as much anxiety as the financial documents. You might be asking: “Does my partner make enough money to sponsor me?” or “What exactly am I signing?”

These are normal questions. The affidavit of support for marriage is a critical part of your application. Without it, the U.S. government will almost certainly reject your green card request.

This article is your comprehensive I-864 guide. We will break down what the form is, the income requirements for 2026, and how to fill i-864 correctly so you can move forward with your life together in the United States.

What is the Affidavit of Support for Marriage?

The affidavit of support for marriage is formally known as Form I-864.

When a foreign national applies for a green card, the U.S. government wants to ensure they will not become a “public charge.” In simple terms, the government wants to know that the immigrant won’t rely on government welfare programs like Supplemental Security Income (SSI) or Temporary Assistance for Needy Families (TANF).

By signing the I-864 form, the U.S. citizen spouse (the “Petitioner”) acts as the “Sponsor.” They are signing a legally binding contract with the U.S. government, promising to use their resources to support the intending immigrant if necessary.

Who must file it? Virtually everyone applying for a family-based green card must submit a signed Form I-864. Even if the immigrant spouse is wealthy and has a high-paying job, the U.S. citizen petitioner must still file this form.

Financial Requirements for the Affidavit of Support for Marriage

This is the most confusing part for most couples. To qualify as a sponsor, you must meet specific income criteria based on your “household size.”

The 125% Rule

USCIS requires the sponsor to have an income that is at least 125% of the Federal Poverty Guidelines for their household size.

Note: These guidelines are updated every year (usually in early Spring). Since you are applying in 2026, you must use the most current numbers.

How to Calculate Household Size Your household size includes:

1. The Sponsor (U.S. Citizen).
2. The Beneficiary (Immigrant Spouse).
3. Any dependent children (under 21 and unmarried) listed on the sponsor’s tax returns.
4. Any other dependents listed on the sponsor’s tax returns.
5. Anyone else the sponsor has previously sponsored using Form I-864 (if they are not yet citizens or have not lost status).

2026 Income Threshold Estimates

Disclaimer: Poverty guidelines change annually. Always check the specific USCIS I-864P page for the exact current figures.

For most couples without children, the household size is 2.

• Household of 2: Requires an annual income of approximately $27,550 (Estimated 2026 figure).
• Household of 3: Requires an annual income of approximately $34,700 (Estimated 2026 figure).
• Household of 4: Requires an annual income of approximately $41,850 (Estimated 2026 figure).

Note: The requirements are higher for residents of Alaska and Hawaii.

Which Income Do They Look At?

USCIS looks at the “Total Income” (or Adjusted Gross Income) from your most recent federal tax return. They also look at your “Current Annual Income”—what you are earning right now based on pay stubs and employment letters.

What If the Sponsor Doesn’t Make Enough Money?

If the U.S. citizen sponsor is a student, unemployed, or retired, they might not meet the 125% requirement. Don’t panic. You have three main options to satisfy the affidavit of support for marriage requirements.

Option 1: Use Assets

If your income is low, you can use assets to make up the difference. Assets can include cash in savings accounts, stocks, bonds, or property (like a house) minus any debt/mortgage.

The 3x Rule: For marriage-based cases, the value of your assets must be 3 times the difference between your income and the requirement.

• Example: You are short by $5,000. You need $15,000 in accessible assets ($5,000 x 3).

Option 2: A Joint Sponsor

This is the most common solution. A Joint Sponsor is a U.S. citizen or Green Card holder who agrees to accept legal responsibility for the immigrant spouse alongside the main sponsor.

• The Joint Sponsor must make 125% of the poverty guideline for their own household size plus the immigrant.
• They do not need to be related to you. They can be a friend or family member.
• They must live in the United States.

Option 3: Household Member Income

If you live with a parent, sibling, or adult child who earns money, you may be able to include their income in your total. They will need to sign Form I-864A (Contract Between Sponsor and Household Member).

I-864 Guide: How to Fill Out the Form (Step-by-Step)

If you are filling this out yourself, here is a general i-864 guide to the sections on the 2026 version of the form.

Part 1: Basis for Filing

This asks why you are filing. As a person sponsoring their spouse, you will usually check the first box: “I am the petitioner. I am filing for… my spouse.”

Part 2 & 3: Information About the Principal Immigrant and Sponsor

These sections are straightforward (Name, Address, SSN).

• Tip: Ensure the “Mailing Address” is secure. This is where USCIS sends correspondence.

Part 5: Sponsor’s Household Size

Crucial Step: Be careful not to double-count people. The form automatically counts the Petitioner (1) and the Immigrant (1). Do not list your spouse again in the “persons you are married to” box, or your household size will be wrong.

Part 6: Sponsor’s Employment and Income

This is the heart of the form.

1. Employed: List your current employer and your Current Individual Annual Income. This is what you expect to earn this year.
2. Tax Information: You must provide information from the last 3 years of tax returns. The “Total Income” figure comes directly from your IRS 1040 form.

Part 8: Sponsor’s Contract

The sponsor must read and sign. By signing, you agree that the government can sue you if the immigrant receives means-tested public benefits.

Required Documents Checklist

To support your i-864 form, you must attach evidence. If you miss these, you will get a “Request for Evidence” (RFE), which delays your green card by months.

• Proof of U.S. Citizenship/Status: Copy of Birth Certificate, Passport, or Green Card.
• Federal Tax Return: The most recent tax return (Form 1040) and all W-2s and 1099s.
  • Pro Tip: We highly recommend downloading the IRS Tax Return Transcript from the IRS website. It replaces the need for the 1040+W2s and is preferred by USCIS.
• Proof of Current Income:
  • Recent pay stubs (last 6 months recommended).
  • Employment verification letter (on company letterhead showing start date and salary).
• Asset Proof (if applicable): Bank statements for the last 12 months, property deeds, or stock certificates.

Common Mistakes to Avoid

Even smart people make mistakes on the affidavit of support for marriage. Here are the top errors we see in 2026:

1. Leaving Fields Blank: Never leave a mandatory field blank. If the answer is none, type “N/A” or “0”.
2. Missing Signature: It sounds obvious, but forgetting to sign the paper form in black ink is a top rejection reason.
3. Wrong Tax Year: Always use the tax return for the most recent filing year. If you haven’t filed yet (and it’s tax season), you must provide proof of an extension or file immediately.
4. Mixing up “Total Income” vs. “Adjusted Gross Income”: The form asks for specific lines from your 1040. Read the instructions carefully to pick the right number.
5. Not Including W-2s: If you submit a photocopy of your 1040, you must attach W-2s. (This is why the IRS Transcript is better—it doesn’t require W-2s).

Real-Life Scenarios

Scenario A: The Student Couple

Situation: Sarah (USC) is a medical student. She has no income. She married Alejandro (Mexican national). Solution: Sarah must still file an I-864 as the main sponsor, even with $0 income. However, they need a Joint Sponsor. Sarah’s father, Bob, earns $80,000/year. Bob files a separate I-864. Sarah files her I-864. Alejandro gets his green card.

Scenario B: The Self-Employed Freelancer

Situation: Mike (USC) is a graphic designer. His “gross” revenue is $60,000, but after business deductions, his “net” income on his taxes is only $18,000. The Problem: $18,000 is below the poverty guideline for a household of 2. Solution: Mike needs to use assets or a joint sponsor, even though his business “made” $60k. USCIS cares about the taxable income after deductions.

Frequently Asked Questions (FAQ)

1. Is there a filing fee for the I-864?

Usually, no. If you are filing for Adjustment of Status (from inside the U.S.) with Form I-485, there is no separate fee for the I-864. However, if you are applying via Consular Processing (spouse is outside the U.S.), the National Visa Center charges a processing fee (approx. $120 in 2026).

2. Can the immigrant spouse’s income count?

Yes, but with strict conditions. The immigrant’s income can be included in the household total if the income comes from a lawful source and will continue after the green card is granted. This usually means the immigrant is already in the U.S. working with a valid work permit (EAD) or H1B visa.

3. What happens if we get divorced?

This is important: Divorce does not end the Affidavit of Support. The sponsor is financially responsible for the beneficiary until the beneficiary becomes a U.S. citizen, earns 40 quarters of work credit (about 10 years), dies, or leaves the U.S. permanently.

4. Can I sponsor my spouse if I am unemployed?

Yes, you can be the sponsor, but you will not meet the financial requirements on your own. You must file the petition, but you will need a Joint Sponsor to provide the financial backing.

5. Does the Joint Sponsor have to be a family member?

No. A Joint Sponsor can be anyone who is at least 18 years old, a U.S. citizen or Green Card holder, and lives in the United States (domiciled). It could be a friend, a neighbor, or an employer.

Conclusion

The affidavit of support for marriage is more than just a form; it’s a promise. While the i-864 form can feel invasive and complicated, it is the key to proving that your future in the United States is secure.

Remember to check the 2026 income guidelines, gather your tax transcripts early, and be honest about your household size. One small math error shouldn’t stand in the way of your life together.
