Form I-864A, Contract Between Sponsor and Household Member, is the form a sponsor’s relative or tax dependent signs so the sponsor can count that person’s income and assets toward the Affidavit of Support. By signing it, the household member promises to help support the intending immigrant and becomes legally responsible, together with the sponsor, for the obligations in the sponsor’s Form I-864. USCIS publishes the form and its instructions on its Form I-864A page, and there is no filing fee. It solves a common problem: a sponsor who falls short of the income requirement alone but lives with a working spouse, parent, adult child, or sibling. Used correctly, it can save a case. Used carelessly, it leads to a Request for Evidence or a refusal at the consulate.
The short version
Form I-864A lets a sponsor add a household member’s income to the Affidavit of Support. The household member must be a relative who lives with the sponsor or a dependent listed on the sponsor’s most recent federal tax return. Both the sponsor and the household member sign. The household member becomes jointly responsible for supporting the immigrant, and that responsibility can last for years. Since the end of August 2026, USCIS has required a new edition of the affidavit of support forms, so an old copy downloaded months ago can get your filing rejected.
Key Takeaways
- Only relatives who share the sponsor’s home, or people listed as dependents on the sponsor’s latest federal tax return, can sign Form I-864A. A roommate or unmarried partner usually cannot.
- Signing Form I-864A is a binding contract. The household member can be held responsible for supporting the immigrant and for repaying certain public benefits.
- Use the current edition from uscis.gov, include the household member’s tax evidence, and make sure the household size on Form I-864 matches the people actually counted.
If you are new to the affidavit of support process, start with our explanation of what sponsorship means in immigration. This guide focuses on one piece of that puzzle: the household member contract.
What is Form I-864A used for?
Most family-based green card cases require the petitioner to file Form I-864, Affidavit of Support, showing household income of at least 125 percent of the federal poverty guidelines for the sponsor’s household size (100 percent for certain sponsors on active military duty sponsoring a spouse or child). USCIS publishes the current thresholds on Form I-864P, and we break down how to read them in our post on green card income requirements for sponsors under the 2026 poverty guidelines.
When the sponsor’s own income does not reach the required amount, there are three main ways to close the gap: count the sponsor’s assets, add a joint sponsor, or add household members’ income. Form I-864A is the tool for the third option. Under the regulations at 8 CFR 213a.1, "household income" can include the income of certain relatives and dependents, but only if those people formally commit to supporting the immigrant. Form I-864A is that commitment.
The key difference from a joint sponsor is that a household member does not file a separate affidavit. Their income is combined with the sponsor’s on one Form I-864. A joint sponsor, by contrast, must qualify entirely on their own. We compare the two options in our guide to choosing a joint sponsor for Form I-864.
Who counts as a household member for Form I-864A?
This is where most problems start. The regulations define a "relative" for these purposes as a spouse, parent, child, adult son or daughter, brother, or sister, according to the definitions in 8 CFR 213a.1. Based on those definitions and the Form I-864A instructions, a person can sign as a household member if they are:
- A relative of the sponsor (from the list above) who lives in the same principal residence as the sponsor, or
- Any person the sponsor listed as a dependent on the sponsor’s most recent federal income tax return, whether or not that person lives with the sponsor.
The household member also needs to be an adult who can sign a binding contract, so a minor child’s income generally will not come in through Form I-864A.
What does not work: a friend who rents a room, a boyfriend or girlfriend the sponsor is not married to, a cousin, an aunt, or an in-law, unless that person is claimed as a dependent on the sponsor’s tax return. If someone outside the definition wants to help, the right path is usually to serve as a joint sponsor instead, if they qualify independently.
Does the intending immigrant need to sign Form I-864A?
Sometimes, and this trips up many couples. The intending immigrant’s own income can count toward the sponsor’s household income if the immigrant is the sponsor’s spouse or already lives with the sponsor, and the income will continue from the same source after the green card is approved. That situation comes up often when a spouse is adjusting status inside the United States and already working with a valid work permit.
According to the I-864A instructions, the intending immigrant does not need to sign Form I-864A to have their income counted unless they are the sponsor’s spouse and have accompanying dependents, such as children immigrating with them. In that case, the immigrant spouse signs Form I-864A to commit to supporting those dependents. In our experience, unnecessary I-864A forms from the intending immigrant are not fatal, but missing ones when dependents are involved can stall a case.
What does the household member promise by signing?
Form I-864A is a contract, and the household member should read it as one. By signing, the household member agrees to provide whatever support is necessary to help the sponsor maintain the intending immigrant at the required income level and agrees to be jointly and severally liable for the sponsor’s obligations under Form I-864. The regulations at 8 CFR 213a.2 treat the household member’s contract as part of the sponsor’s support obligation.
"Jointly and severally liable" means the immigrant, or a government agency that provided certain means-tested public benefits, could seek the full amount from the sponsor, from the household member, or from both. Under INA section 213A (8 U.S.C. 1183a), the support obligation generally continues until the immigrant becomes a U.S. citizen, can be credited with 40 quarters of work, leaves the United States permanently and loses permanent resident status, or dies. A divorce between the sponsor and the immigrant does not end it.
That is a serious commitment. Before an adult child or sibling signs, we want them to understand it is not a reference letter. It can follow them for a decade or longer.

What documents go with Form I-864A?
The Form I-864A instructions list the evidence. In practice, we assemble:
- The household member’s federal tax evidence for the most recent tax year, either a transcript from the IRS or a copy of the return with W-2s and 1099s.
- Proof of current income, such as recent pay stubs or an employer letter, so the officer can see the income is ongoing.
- Proof of the relationship to the sponsor, such as a birth or marriage certificate, unless the person is listed as a dependent on the sponsor’s tax return.
- Proof of shared residence for relatives who qualify by living with the sponsor, such as a lease, mortgage statement, or mail at the same address.
- Asset evidence, if the household member’s assets are being counted, such as bank statements.
Each household member completes a separate Form I-864A. The sponsor signs each one too.
How and where is Form I-864A filed?
Form I-864A is never filed by itself. It travels with the sponsor’s Form I-864.
Adjustment of status inside the U.S. If the immigrant is applying for a green card with Form I-485, the I-864 and any I-864A forms are filed with the adjustment package, as USCIS explains on its affidavit of support page. The officer may ask about the household member’s finances at the interview, so the household member’s information should be current. Our guide to the adjustment of status interview covers what to bring.
Consular processing abroad. If the immigrant is getting an immigrant visa at a U.S. embassy or consulate, the financial documents are uploaded to the National Visa Center through the Consular Electronic Application Center. The State Department’s Affidavit of Support FAQs describe how NVC and consular officers review these forms. You can follow the full sequence in our NVC process guide.
What changed with Form I-864A in 2026?
In late August 2026, USCIS released new editions of the affidavit of support forms, including Form I-864A, and required the new editions starting August 31, 2026 with no grace period for older versions. The new editions also add language authorizing the government to obtain consumer or credit reports in connection with the affidavit. Before anyone signs, download the form fresh from the USCIS Form I-864A page and confirm the edition date printed at the bottom of each page matches the edition USCIS currently accepts. If a household member signed an older edition months ago and the packet has not been filed, plan on having them sign again.
What are the most common Form I-864A mistakes?
These are the errors we see most when families prepare the forms on their own:
- Using a household member who does not qualify. A roommate, unmarried partner, or in-law who is not a tax dependent cannot sign. USCIS will not count that income.
- Household size that does not match. Every household member whose income is counted must also be included in the household size on Form I-864. Adding a person’s income without adding the person raises the threshold you need to meet, and officers check the math.
- Outdated form edition. Given the 2026 change, this is the fastest way to get a filing rejected.
- Missing or mismatched tax evidence. If the household member’s tax return shows less income than Form I-864 claims, or the return is missing, expect a Request for Evidence.
- Income that will not continue. Income from a job the household member is about to leave, or from a person about to move out, does not help. The income must reasonably be expected to continue.
- Missing signatures. Both the sponsor and the household member must sign. An unsigned page sends the packet back.
- Confusing a household member with a joint sponsor. A parent who does not live with the sponsor and is not a tax dependent cannot sign Form I-864A, but may be able to serve as a joint sponsor on a separate Form I-864.
Frequently Asked Questions
Is there a fee to file Form I-864A?
No. USCIS does not charge a filing fee for Form I-864A. It is filed together with Form I-864 as part of the green card or immigrant visa case. Check the USCIS Form I-864A page for the current edition.
Can my unmarried partner sign Form I-864A?
Generally no, unless you list them as a dependent on your most recent federal tax return. The regulations limit qualifying relatives to a spouse, parent, child, adult son or daughter, and sibling. Your partner may be able to serve as a joint sponsor instead if they meet the income requirement on their own.
Can a household member withdraw after signing?
Once the immigrant becomes a permanent resident based on the affidavit, the household member’s obligations generally continue until a terminating event, such as the immigrant naturalizing or being credited with 40 quarters of work. Before the case is approved, a household member who no longer wants to participate should tell the sponsor right away so the case can be restructured.
Does my spouse need to sign Form I-864A if I am using their income?
If your spouse is a household member who is not the immigrant, yes. If your spouse is the intending immigrant, they generally sign Form I-864A only when they have accompanying dependents, according to the USCIS instructions.
How We Can Help
Form I-864A looks like a simple add-on, but it sits at the center of the financial side of a green card case.
