What Is a Joint Sponsor for I-864: Income Rules and Liability

A joint sponsor for the I-864 is a second person who files their own Form I-864, Affidavit of Support, to independently meet the income requirement when the petitioning sponsor’s income falls below 125 percent of the Federal Poverty Guidelines. The joint sponsor doesn’t need to be related to the petitioner or the immigrant, but by signing they take on a legally enforceable financial obligation that can last for years and survive events like divorce or bankruptcy.¹

How the Role Works

The petitioner (the person who filed the immigration petition) always has to submit an I-864, even when their income is too low to qualify. When it is, a joint sponsor steps in with a completely separate I-864 of their own.² The joint sponsor’s income is evaluated on its own. It does not top off the petitioner’s earnings. The joint sponsor must meet the full income threshold independently.

Signing creates what’s called “joint and several liability” with the petitioner. Either party can be pursued for the full amount owed if the immigrant receives certain public benefits. It isn’t a 50/50 split. Both are on the hook for the entire obligation.³

Up to two joint sponsors can be used per family petition. If a petitioner is bringing a spouse and two children, one joint sponsor might cover the spouse and a second cover the children. Each joint sponsor is responsible only for the immigrants listed on their own I-864.⁴ A joint sponsor cannot combine income with the petitioner or with another joint sponsor.²

Joint Sponsor Is Not the Same as Household Member

People confuse these two roles constantly. A joint sponsor files their own I-864 and independently meets the income threshold. A household member files Form I-864A, which pools their income with the petitioning sponsor’s to help the petitioner qualify.⁵

Household members must have a specific tie to the petitioner. They can be the petitioner’s spouse, a parent, child, adult son or daughter, or sibling living at the same address, or anyone the petitioner legally claimed as a dependent on their most recent tax return.⁶ A joint sponsor faces no relationship requirement at all. A friend, coworker, or distant acquaintance can serve, as long as they meet the eligibility rules and are willing to take on the obligation.

The practical distinction: if the petitioner’s brother earns $20,000 and lives with the petitioner, that brother can use an I-864A to add his income to the petitioner’s total. If a friend in another state wants to help, that friend has to serve as a joint sponsor with their own I-864 and clear the full income threshold on their own.

Who Can Serve as a Joint Sponsor

A joint sponsor must meet every one of these requirements:

Be at least 18 years old.
Be a U.S. citizen, lawful permanent resident, or U.S. national.
Have a primary residence in the United States or its territories.
Independently show annual income at or above 125 percent of the Federal Poverty Guidelines for their household size.²

The household size calculation trips people up. It includes the joint sponsor, their own dependents, anyone they’ve previously sponsored on another I-864 whose obligation hasn’t ended, and the new immigrant they’re agreeing to sponsor. A joint sponsor with two dependents who previously sponsored one immigrant already has a household size of four before the new immigrant is even added.

The domicile requirement has one narrow exception. People working abroad for the U.S. government or for a public international organization the United States participates in by treaty are considered domiciled in the United States despite living overseas.²

2026 Income Thresholds

The income threshold is tied to the HHS poverty guidelines and updates every year. The 2026 figures took effect on March 1, 2026. For the 48 contiguous states, the District of Columbia, Puerto Rico, Guam, the U.S. Virgin Islands, and the Northern Mariana Islands, 125 percent of the guidelines is:⁷

Household of 2: $27,050
Household of 3: $34,150
Household of 4: $41,250
Household of 5: $48,350
Household of 6: $55,450
Household of 7: $62,550
Household of 8: $69,650

Alaska and Hawaii have higher thresholds. For a household of two, Alaska’s 125 percent figure is $33,813 and Hawaii’s is $31,113.⁷

Using Assets When Income Falls Short

If a joint sponsor’s income doesn’t reach the threshold, assets can close the gap. The math is not one-to-one. The total value of qualifying assets must equal at least five times the difference between the sponsor’s household income and the required amount.²

Say a joint sponsor’s household income is $23,050 and the threshold for their household size is $27,050. The gap is $4,000. They’d need at least $20,000 in qualifying assets, five times the shortfall.

Qualifying assets include savings, stocks, bonds, certificates of deposit, and real estate beyond the sponsor’s primary residence. The critical restriction is that the asset must be convertible to cash within one year without significant financial loss to the owner. Retirement accounts with early-withdrawal penalties and property that would sell at a steep loss generally don’t count. Documentation has to show clear ownership and a reliable valuation from a financial institution or certified appraiser.

What Documents the Joint Sponsor Submits

A joint sponsor sends in a complete evidence packet along with their separate I-864:

A copy of the federal individual income tax return for the most recent tax year, with all W-2s, 1099s, and schedules. An IRS tax transcript is an acceptable alternative that many practitioners prefer. Returns for the two additional prior years can be included if they strengthen the case.²
Recent pay stubs or an employment verification letter showing current income.
For self-employed sponsors, whichever IRS schedules apply: Schedule C for business income, Schedule D for capital gains, Schedule E for rental or partnership income, Schedule F for farming income.²
If assets are being used, bank statements, brokerage statements, appraisals, or other evidence of ownership and value.
Proof of citizenship or lawful permanent resident status: birth certificate, U.S. passport, naturalization certificate, or green card.

The income figure entered on the form comes from the sponsor’s adjusted gross income on their tax return. If current pay has risen significantly since the last filing, pay stubs and an employer letter can show the higher salary and help demonstrate the sponsor now clears the threshold.

What Signing the I-864 Legally Commits You To

The I-864 is a contract enforceable in federal and state court, and courts treat it that way.¹ Two obligations attach the moment the immigrant becomes a lawful permanent resident.

Reimbursing Federal Means-Tested Benefits

If the sponsored immigrant receives certain federal public benefits, the agency that provided them can demand reimbursement from the joint sponsor. The programs that trigger this are:⁷

Supplemental Security Income (SSI)
SNAP (food stamps)
Temporary Assistance for Needy Families (TANF)
Non-emergency Medicaid
State Children’s Health Insurance Program (SCHIP)

Several programs are excluded, including emergency Medicaid, school lunch programs, immunizations and treatment for communicable diseases, Head Start, and certain foster care or adoption assistance.⁷

The Immigrant Can Sue You Directly

The sponsored immigrant is treated as a third-party beneficiary of the I-864 contract. If the sponsor fails to keep the immigrant at 125 percent of the poverty line, the immigrant can file a lawsuit in federal or state court to enforce that obligation. Signing the form means agreeing to submit to the jurisdiction of any court where such a suit is brought.⁸

Courts have consistently held that divorce does not end the sponsor’s support obligation. A prenuptial agreement purporting to waive I-864 support has been rejected by the vast majority of courts. Courts have generally refused to reduce the support amount because the immigrant moved in with a new partner or could theoretically find work. The sponsor promised the poverty-line figure and courts hold them to it regardless of changed personal circumstances.

The obligation has also been treated as a non-dischargeable domestic support obligation in bankruptcy, meaning a sponsor cannot wipe out this debt by filing for bankruptcy protection.

When the Obligation Ends

The joint sponsor’s liability isn’t permanent, but it lasts longer than most people expect. It ends only when one of these happens:¹

The immigrant becomes a U.S. citizen.
The immigrant is credited with 40 qualifying quarters of work under Social Security (roughly 10 years). Quarters earned by a spouse during marriage can count, but any quarter in which the immigrant received federal means-tested benefits after December 31, 1996, doesn’t.⁸
The sponsored immigrant dies, or the sponsor dies.²
The immigrant loses lawful permanent resident status through removal or voluntary abandonment.

Divorce, separation, the immigrant moving out, or a personal falling out does not end the obligation. Neither does the immigrant getting a well-paying job, though a fully employed immigrant is unlikely to trigger benefit reimbursement or a support lawsuit in practice.

Reporting Address Changes

A joint sponsor must file Form I-865, Sponsor’s Notice of Change of Address, within 30 days of any move while the affidavit is still enforceable.⁹ Lawful permanent residents who are also sponsors have to file both I-865 and comply with the standard 10-day address change rule under immigration regulations.¹⁰

The civil fines for failing to report come in two tiers:

Standard failure: $250 to $2,000.
Failure with knowledge that the immigrant received means-tested benefits: $2,000 to $5,000.¹¹

Where the Form Goes

The joint sponsor gives their completed I-864 and supporting documents to the immigrant, who submits them with the rest of the application. Where the packet is filed depends on where the immigrant is applying from:

Inside the United States: with USCIS alongside Form I-485, Application to Register Permanent Residence.¹²
Outside the United States: with the Department of State’s National Visa Center as part of consular processing.

A physical signature is required. Typed or digital signatures will be rejected.

Backing Out Before the Green Card Is Issued

A joint sponsor can generally withdraw their I-864 before the immigrant receives their green card or immigrant visa, because the legal obligation doesn’t attach until the immigrant is actually admitted as a permanent resident. The practical route is written notice to USCIS or the National Visa Center. Withdrawal leaves the petitioner scrambling to find a replacement or qualify alone, which will delay the case. Once the immigrant has been admitted, withdrawal is no longer available. The obligation is locked in and ends only through the events listed above.
