I-864 Affidavit of Support: Your 2026 Guide to Sponsor Requirements, Income Rules, and Long-Term Obligations

What Is Form I-864 and Why It Matters

Form I-864, the Affidavit of Support Under Section 213A of the Immigration and Nationality Act, is one of the most important documents in nearly every family-based green card case. It is the sponsor's promise, made directly to the federal government, that the sponsored immigrant will not become dependent on public benefits and that the sponsor will provide financial support if needed.

The legal authority for Form I-864 comes from Section 213A of the INA, codified at 8 U.S.C. 1183a, and from the implementing regulations at 8 C.F.R. 213a and 22 C.F.R. 40.41. The form itself is published by U.S. Citizenship and Immigration Services and is required by both USCIS and the Department of State.

Many families come to my office in Massachusetts focused on the love story behind their case, the marriage certificate, or the police report from the consulate appointment, and they are caught off guard by the I-864 requirement. The I-864 is not a formality. It is a long-term contract with real financial consequences. Understanding how it works before you sign it is one of the most important things you can do.

Who Has to File a Form I-864?

The Affidavit of Support is required in most family-based immigration cases and in a small subset of employment-based cases. Specifically, an I-864 is generally required when the immigrant is applying for an immigrant visa or adjustment of status as:

• An immediate relative of a U.S. citizen (spouse, unmarried child under 21, or parent of a U.S. citizen who is at least 21)
• A family preference immigrant under the F1, F2A, F2B, F3, or F4 categories
• An employment-based immigrant where the petitioner is a relative or has a significant ownership interest of 5 percent or more in the petitioning entity

There are limited cases where the I-864 is not required, such as widows and widowers of U.S. citizens self-petitioning under Form I-360, VAWA self-petitioners under Form I-360, and certain Special Immigrant Juveniles. Children who will automatically acquire U.S. citizenship under the Child Citizenship Act of 2000 upon admission as lawful permanent residents are also exempt. When the I-864 is not required, applicants generally claim the exemption directly on Form I-485 (USCIS retired the standalone Form I-864W in 2019) or, in consular cases, by written notice to the National Visa Center.

The Petitioner Sponsor: Baseline Requirements

If you filed the Form I-130 petition that started your relative's case, you are the petitioning sponsor, and you must file an I-864. This requirement is not optional. It exists even if you have very low income, no income at all, or believe a joint sponsor will carry the case. To qualify as a sponsor, you must meet four baseline requirements:

• Age: You must be at least 18 years old at the time of filing.
• Status: You must be a U.S. citizen, U.S. national, or lawful permanent resident.
• Domicile: Your principal residence must be in the United States, or you must demonstrate that you have re-established or will re-establish U.S. domicile by the time the immigrant is admitted.
• Income or assets: Your household income, supplemented by qualifying assets if needed, must equal at least 125 percent of the Federal Poverty Guidelines for your household size.

If you fail any one of these requirements, you still file the I-864, but you will need either a household member to contribute income on Form I-864A or a joint sponsor on a separate I-864 of their own.

The 125 Percent Rule and the 2026 Poverty Guidelines

The Department of Health and Human Services publishes the Federal Poverty Guidelines every year. USCIS adopts those numbers in Form I-864P, which is the chart sponsors actually use when filling out the I-864. The 2026 HHS Poverty Guidelines were published in the Federal Register on January 15, 2026 and went into effect for I-864 purposes on March 1, 2026.

For the 48 contiguous states and the District of Columbia, the 125 percent thresholds for 2026 are $27,050 for a household of 2 and $41,250 for a household of 4. The 100 percent figure (used by active duty military sponsors) is $21,640 for a household of 2. Alaska and Hawaii use higher figures because the federal poverty guidelines for those states are higher. Always check the current Form I-864P on the USCIS website before filing, because the numbers change every year.

How to Count Your Household

Counting your household correctly is one of the most common stumbling blocks on the I-864. Your household size for I-864 purposes includes you, your spouse, your unmarried children under 21, any other dependents listed on your most recent tax return, the immigrants you are now sponsoring on the I-864, and any other immigrants you previously sponsored under any prior I-864 whose obligations have not yet terminated.

If two people in your household share a child or already file taxes jointly, only count that child once. Do not double count. If you are not sure, ask your attorney to walk through the math with you before you sign.

Joint Sponsors and Household Members: Two Different Roles

One of the most misunderstood parts of the I-864 is the difference between a joint sponsor and a household member. These are two separate paths to filling an income gap, and they use different forms.

The Household Member (Form I-864A)

A household member is a person who lives at the same address as the petitioning sponsor and is willing to combine their income, and sometimes assets, with the petitioner's. The household member signs Form I-864A, the Contract Between Sponsor and Household Member, which becomes a legally binding agreement to make their income available to the sponsor for support purposes.

To use Form I-864A, the household member must be at least 18 years old and must live with the sponsor, unless the household member is the intending immigrant themselves (a special rule that occasionally allows the immigrant to use their own income). The household member does not have to be a U.S. citizen or lawful permanent resident. They can be a working spouse, an adult child, or another relative whose income is reported to the IRS at the same household address.

The Joint Sponsor

A joint sponsor is a completely separate person who files their own Form I-864 on behalf of the immigrant. The joint sponsor does not need to live with the petitioner and does not need to be related to anyone in the case. The joint 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
• Independently meet 125 percent of the Federal Poverty Guidelines for the joint sponsor's own household plus all of the immigrants the joint sponsor is sponsoring

A case may have no more than two joint sponsors total, and each joint sponsor must independently qualify for all the immigrants they are sponsoring. You cannot combine the income of two joint sponsors. Each one must meet 125 percent on their own.

Using Assets to Make Up for Income

If your income alone does not reach 125 percent of the poverty line, you can supplement it with qualifying assets. The assets must be available to be converted to cash within one year without considerable hardship to you or your family. Common qualifying assets include savings accounts, certificates of deposit, stocks and bonds, and real estate equity beyond the home you actually live in.

The multiplier depends on the sponsor and the immigrant:

• Standard rule: Total qualifying assets must equal at least 5 times the difference between the sponsor's household income and 125 percent of the poverty guidelines.
• U.S. citizen sponsoring a spouse or minor child: The multiplier drops to 3 times the difference.
• Orphan adoption cases: A 1-to-1 multiplier applies for orphans coming to the United States who will become U.S. citizens upon admission under the Child Citizenship Act.

If you plan to rely on assets, document them carefully. USCIS and the National Visa Center commonly ask for bank statements, broker statements, appraisals, and proof that the asset is in your name and is liquid.

What Tax Documents You Need to File

The I-864 requires you to provide a complete copy of your federal income tax return, or an IRS tax transcript, for the most recent tax year. You may voluntarily attach returns or transcripts for the two prior years if doing so helps show a stable or increasing income pattern. Most immigration attorneys recommend providing all three years when income has gone up over time, because it strengthens the case.

If you were not required to file a federal tax return for a given year under IRS rules, such as because your income fell below the filing threshold, attach a written statement explaining why and cite the IRS rule that applied. You should also include a current letter from your employer, recent pay stubs covering the last six months, and any documentation of self-employment or business income.

How Long the I-864 Obligation Lasts

Many sponsors are surprised to learn that the I-864 obligation is not tied to the green card process. It is a long-term contract enforceable in federal court. The obligation continues until one of five specific events occurs:

• The sponsored immigrant becomes a U.S. citizen through naturalization or otherwise
• The sponsored immigrant is credited with 40 qualifying quarters of work under the Social Security Act (usually about 10 years, with quarters earned by the immigrant or counted from a spouse during marriage)
• The sponsored immigrant permanently abandons lawful permanent resident status and physically departs the United States
• The sponsored immigrant dies
• The sponsor dies (the sponsor's estate is not generally on the hook for future support, though it may still be liable for reimbursing past benefits)

What does not terminate the I-864 obligation? Divorce. This is the single most common mistake I see. A sponsor and an immigrant may divorce, the marriage may have been brief, and they may want nothing more to do with each other, and yet the sponsor's financial obligation under the I-864 continues until one of the five events above occurs. Federal courts have repeatedly enforced this rule, and a former spouse can sue the sponsor for support shortfalls below 125 percent of the poverty line even after divorce.

Means-Tested Public Benefits and Deeming

Closely connected to the I-864 is the concept of "deeming." When the sponsored immigrant applies for certain federal means-tested public benefits, the federal agency administering the program may "deem" the sponsor's income and assets to be available to the immigrant for purposes of eligibility. Programs that are subject to deeming under federal law include Supplemental Nutrition Assistance Program (SNAP), Supplemental Security Income (SSI), Temporary Assistance for Needy Families (TANF), Medicaid, and the Children's Health Insurance Program (CHIP).

If the immigrant receives a deemable federal means-tested benefit anyway, the agency that paid that benefit can demand reimbursement from the sponsor. State and local benefit agencies have similar deeming and reimbursement rules under many state laws. Sponsors should understand that the I-864 creates real financial exposure if the sponsored immigrant later qualifies for and receives these benefits.

Common Mistakes That Trigger Requests for Evidence

Over the years I have seen the same I-864 mistakes again and again. The good news is that almost all of them are preventable with careful preparation:

• Wrong household size: Forgetting to add the sponsored immigrants, or counting a dependent twice.
• Old poverty guidelines: Using last year's Form I-864P. The guidelines update every year.
• Tax returns out of order: Missing pages, missing W-2s, or filing a transcript that does not match what was sent to the IRS.
• Confusing current income with total income on the tax return: The I-864 asks about current annual individual income on Part 6, which is your present income today, not necessarily the figure on Line 9 of last year's Form 1040.
• Missing the U.S. domicile evidence: If you are a U.S. citizen living abroad, you must specifically document re-establishment of U.S. domicile in time for the immigrant's admission.
• Failing to sign or to use the current edition: USCIS rejects forms with outdated editions or missing signatures.

Frequently Asked Questions About Form I-864

What This Means for Massachusetts Families

For my clients in Massachusetts, especially in the Brazilian, Haitian, Salvadoran, and Cape Verdean communities where multigenerational households are common, the I-864 frequently involves a parent sponsoring an adult child, a citizen child sponsoring a parent, or a spouse who recently became a citizen sponsoring their partner. Two patterns come up over and over:

First, the petitioner is a younger person whose income alone does not meet 125 percent, but a parent, sibling, or adult cousin is willing to step in as a joint sponsor. In those cases, picking the right joint sponsor and gathering their tax documents up front saves months of delay.

Second, the petitioner is a working spouse and the household member is the immigrant's other working family member already living at the same address. Form I-864A can combine those incomes cleanly, but only when the household member's name is on the lease or mortgage and the IRS records line up with the address used on the I-864.

If your case involves a divorce, a previously sponsored relative who has not yet naturalized, or any uncertainty about your tax filing history, do not file the I-864 without first talking to an immigration attorney. The numbers may look right on the form and still trigger a costly Request for Evidence, or worse, an enforceable financial judgment years later.

Final Thoughts

Form I-864 is not paperwork. It is a contract between you and the United States government that may follow you for ten years or more, and that can be enforced in federal court by the immigrant, the government, or both. The good news is that with careful planning, accurate tax records, and the right sponsor or joint sponsor, the I-864 is highly manageable.

If you are preparing a family-based green card case and want to make sure your I-864 will hold up, I can help you walk through the income math, the household count, the joint sponsor or household member decision, and the long-term implications before you sign. Getting it right the first time is far easier than fixing it later.
