What the Affidavit of Support does, who must sign it, how the income requirement works, when a joint sponsor is needed, how household members can contribute, what assets can be used, and when the sponsor’s legal obligation ends.
Form I-864 is the Affidavit of Support that a qualifying financial sponsor signs to accept financial responsibility for an intending immigrant.
It is required for most family-based immigrants and certain employment-based immigrants.
USCIS describes the I-864 as a contract between the sponsor and the U.S. government. The sponsor generally must demonstrate sufficient income or qualifying assets to maintain the household and sponsored immigrant at 125% of the applicable Federal Poverty Guidelines. (uscis.gov)
The Department of State similarly explains that the petitioner must generally submit the I-864 in immigrant-visa cases and that a joint sponsor may be used when the petitioner’s income is insufficient. (travel.state.gov)
The most important distinction is this:
The I-864 is not simply evidence of income.
It creates a sponsorship obligation.
Form I-864 is generally required for:
This includes:
This includes categories such as:
An I-864 can also be required in certain employment-based immigrant cases where a qualifying U.S. citizen, lawful permanent resident or U.S. national relative filed the petition, or where the relative has a significant ownership interest in the petitioning entity.
USCIS identifies these categories in the I-864 instructions. (uscis.gov)
There are also exceptions.
Not every immigrant applying for permanent residence needs an I-864.
Certain applicants may qualify for an exception based on factors such as credited employment quarters, a qualifying minor child of U.S. citizens, or other statutory circumstances.
The exception should be established legally rather than assumed.
The person signing the I-864 is called the sponsor.
In a family-based immigration case, the petitioner is generally the primary sponsor.
The sponsor must generally:
The Department of State confirms that a petitioner must meet the age, status and domicile requirements to serve as the financial sponsor. (travel.state.gov)
Notice what is not on that list:
The sponsor does not automatically have to be wealthy.
The law focuses on whether the sponsor meets the applicable financial requirements, not whether the sponsor owns a house or has substantial savings.
Domicile is one of the most commonly overlooked I-864 requirements.
It is not simply the same thing as:
“Where do you happen to be living today?”
For I-864 purposes, domicile generally means the sponsor’s principal residence, with the intention to maintain it for the foreseeable future.
The sponsor generally must be domiciled in:
USCIS and the Department of State recognise circumstances in which a U.S. citizen or lawful permanent resident may be temporarily abroad while retaining U.S. domicile. (travel.state.gov)
For example, a U.S. citizen may temporarily work overseas while maintaining:
A sponsor who has moved permanently overseas and no longer maintains U.S. domicile may face a different problem.
And there is an important rule:
A joint sponsor does not cure a petitioner’s failure to meet the basic sponsor requirements.
The petitioner must still qualify as a sponsor in terms of age, immigration status and domicile, even when a joint sponsor is added because the petitioner’s income is insufficient. (travel.state.gov)
The standard rule is generally:
125% of the Federal Poverty Guidelines for the sponsor’s household size.
Active-duty members of the U.S. Armed Forces who are sponsoring a spouse or minor child generally have a lower threshold of:
100% of the applicable Federal Poverty Guidelines.
USCIS confirms this distinction in the I-864 instructions. (uscis.gov)
This is why saying:
“You need to earn $X to sponsor someone.”
is incomplete.
The required income depends on:
The HHS poverty guidelines were updated for 2026.
For the 48 contiguous states and District of Columbia, the poverty guideline is:
Household Size | 100% | 125% |
1 | $15,960 | $19,950 |
2 | $21,640 | $27,050 |
3 | $27,320 | $34,150 |
4 | $33,000 | $41,250 |
5 | $38,680 | $48,350 |
6 | $44,360 | $55,450 |
7 | $50,040 | $62,550 |
8 | $55,720 | $69,650 |
For household sizes over eight, the 2026 guideline increases by $5,680 per additional person for the 125% calculation in the contiguous states and D.C. (aspe.hhs.gov)
For Alaska and Hawaii, separate federal poverty guidelines apply, so the figures are higher. (aspe.hhs.gov)
These are the 2026 figures.
They should not be treated as permanent numbers.
HHS updates the poverty guidelines annually, and I-864 financial requirements should be checked against the applicable guidelines when preparing the filing.
This is where many otherwise qualified sponsors make mistakes.
You do not simply count:
“How many people live in my house?”
The I-864 household calculation can include people the sponsor is financially responsible for even when they do not live in the same home.
The calculation generally includes:
USCIS’s I-864 instructions explain the household-size calculation in detail. (uscis.gov)
This means a sponsor with a modest income may find that the applicable household size is larger than expected.
And once household size increases, the required income increases.
Imagine a U.S. citizen sponsoring a spouse.
The sponsor:
The household is not simply:
2 people
It may be:
Sponsor + spouse + two children + intending immigrant = 5
That means the sponsor must generally meet the 125% guideline for a household of five, rather than a household of two.
At the 2026 contiguous-state level, that means approximately:
$48,350
rather than:
$27,050
That difference can completely change the financial analysis.
The sponsor generally reports current individual annual income.
The evidence can include documentation such as:
The Department of State’s financial-evidence guidance emphasises documentation supporting the sponsor’s income and financial circumstances. (travel.state.gov)
One important point:
Taxable income and current income are not necessarily the same number.
A sponsor may have circumstances in which current annual income is different from what appeared on the previous tax return.
That discrepancy should be explained and documented rather than ignored.
There are two major solutions:
A qualifying joint sponsor can independently agree to accept the financial responsibility for the intending immigrant.
Certain household members can contribute income through Form I-864A, Contract Between Sponsor and Household Member.
These mechanisms are similar in purpose but legally different.
That distinction matters.
A joint sponsor is a separate individual who agrees to sponsor the intending immigrant because the petitioning sponsor’s income is insufficient.
The joint sponsor must independently satisfy the relevant requirements.
Generally, a joint sponsor must:
The joint sponsor does not replace the petitioner’s obligation to submit the required affidavit.
The petitioner still submits an I-864 even when a joint sponsor is used. (travel.state.gov)
No.
The joint sponsor does not generally have to be related to the immigrant or the petitioner.
The important issue is whether the person meets the legal requirements.
USCIS has stated that a joint sponsor can be a U.S. citizen, lawful permanent resident or U.S. national who is at least 18, domiciled in the United States and willing to accept the applicable financial responsibility. (uscis.gov)
That means a close friend may potentially qualify just as a relative might.
But the person needs to understand what they are signing.
This is not a courtesy letter.
It is a legal commitment.
Form I-864A, Contract Between Sponsor and Household Member, allows certain household members to make their income and resources available to the sponsor in meeting the I-864 financial requirement.
Eligible household members can include certain:
The household member must meet the applicable requirements and sign Form I-864A.
USCIS explains that certain relatives living at the sponsor’s residence can be included through this mechanism when their income is needed to meet the financial requirement. (uscis.gov)
This can be useful where:
Sponsor’s income alone < required amount
but
Sponsor’s income + qualifying household-member income ≥ required amount
These are often confused.
Household Member | Joint Sponsor |
Generally part of sponsor’s household | Separate sponsor |
Uses Form I-864A | Uses Form I-864 |
Income may be combined with sponsor’s | Independently meets income requirement |
Subject to household-member rules | Does not have to live with petitioner |
Does not replace petitioner’s I-864 | Does not replace petitioner’s I-864 |
Choosing the correct mechanism can make the filing much cleaner.
Potentially, yes.
When the sponsor’s income falls below the required threshold, qualifying assets may sometimes make up the difference.
USCIS allows certain assets to be considered, including:
But the value of the asset is not necessarily equal to the amount of income deficiency.
The law applies specific multiplier rules.
For example, the Department of State explains that for many cases, the sponsor must generally show assets worth five times the difference between actual income and the applicable poverty-guideline requirement.
A lower multiplier can apply in certain spouse/child sponsorship situations involving U.S. citizens. (travel.state.gov)
This is why simply saying:
“I have $20,000 in the bank.”
does not answer the question.
The amount needed depends on:
Potentially.
USCIS and the Department of State recognise circumstances in which assets belonging to the intending immigrant can contribute to the financial calculation.
Requirements apply, including the ability to convert the asset into cash and, in certain cases, move it to the United States.
The intended immigrant may need to complete Form I-864A when their income or assets are being used under the applicable rules.
Again, this is highly fact-specific.
A property overseas is not automatically equivalent to readily available cash.
This can be one of the more complicated I-864 scenarios.
Living abroad does not automatically eliminate the possibility of being the sponsor.
But the sponsor must satisfy the U.S.-domicile requirement.
The Department of State recognises that a U.S. citizen or LPR can sometimes maintain U.S. domicile while temporarily abroad, provided the facts demonstrate continued U.S. ties and an intention to maintain or re-establish U.S. domicile. (travel.state.gov)
A sponsor who cannot establish U.S. domicile may not qualify simply by finding a joint sponsor.
This is an important distinction.
A joint sponsor can solve an income problem.
A joint sponsor does not automatically solve a domicile problem.
Unemployment does not automatically mean the I-864 will fail.
The relevant issue is whether the sponsor can demonstrate sufficient qualifying income and/or qualifying assets under the rules.
For example, a sponsor may have:
But a sponsor should not simply submit an old tax return and assume that proves current financial capacity.
USCIS and the Department of State may require evidence of present income and financial circumstances. (travel.state.gov)
Yes.
This is one of the most important facts about the form.
By signing an I-864, the sponsor accepts a legally enforceable obligation.
The Department of State states that the sponsor’s financial responsibility generally continues until the sponsored immigrant:
One fact surprises many sponsors:
Divorce does not terminate the I-864 obligation.
USCIS’s current I-864 form expressly states this. (uscis.gov)
The financial obligation is tied to the immigration sponsorship, not simply to the continuation of the marriage.
Business owner working on her newly open cafe. From concept to reality.
Potentially.
USCIS explains that a sponsored immigrant may be able to enforce the sponsor’s support obligation through legal action.
A government agency that provides a covered means-tested public benefit may also seek reimbursement from the sponsor under the applicable law. (uscis.gov)
This means the sponsor should understand that signing the form can create real financial consequences.
It is not merely a document for immigration officers.
No.
The I-864 rules concern specific categories of means-tested public benefits and specific legal mechanisms.
Not every government benefit is covered.
USCIS specifically identifies exceptions, including certain emergency and non-cash programmes, and the applicable rules should be reviewed rather than treating all public assistance as equivalent. (uscis.gov)
This is another reason not to reduce I-864 law to:
“The immigrant can never receive benefits.”
That statement is too broad.
The actual rules are more precise.
The income figures change.
For a 2026 filing, use the applicable current 2026 guidelines rather than a 2024 or 2025 chart. (aspe.hhs.gov)
This is one of the most common practical problems.
Some prior sponsorship obligations can still count.
Certain financial responsibilities apply regardless of where the person lives.
The required financial evidence depends on the applicable filing circumstances.
A tax return showing strong historical income does not automatically prove current income.
It does not.
The two mechanisms are not interchangeable.
Income alone does not establish sponsor eligibility.
It generally does not.
Asset multipliers and qualifying-asset rules matter.
This may be the biggest mistake of all.
Suppose a U.S. citizen is sponsoring a spouse and has a household size of four.
For 2026, the applicable 125% threshold for the contiguous United States and D.C. is:
$41,250
The sponsor reports:
$35,000
That creates a shortfall of:
$6,250
The sponsor may need to consider:
The correct solution depends on the circumstances.
The important point is that the case does not necessarily end simply because the petitioner’s salary is below the threshold.
There are structured alternatives.
Imagine the petitioner earns only $30,000.
A friend earns $90,000 and is willing to help.
The friend may potentially qualify as a joint sponsor.
But the friend is not simply “adding $60,000” to the petitioner’s income.
The joint sponsor generally files a separate I-864 and independently assumes the applicable obligations for the sponsored immigrant(s).
The petitioner’s own I-864 remains part of the case.
That legal distinction matters.
A well-organised financial package can include:
For a joint sponsor or household member:
Where needed:
The Department of State’s financial-evidence guidance provides additional documentation requirements for immigrant-visa cases. (travel.state.gov)
This is a situation where precision matters.
Suppose the required figure is:
$41,250
and the sponsor’s documented qualifying income is:
$41,400
Technically, that is above the threshold.
But a case should not necessarily be approached as:
“I am over by $150, so everything is fine.”
Income can change.
Documentation can conflict.
Household size can be miscalculated.
The sponsor’s current income may not match the last tax return.
A small margin can therefore justify a careful documentation strategy.
The aim should be to make the financial picture clear and defensible, not merely technically sufficient on paper.
The most important thing to understand about Form I-864 is that it changes the nature of the sponsor’s involvement.
The sponsor is not merely saying:
“I earn enough money.”
The sponsor is saying:
“I accept financial responsibility under federal immigration law.”
That is materially different.
Before signing, the sponsor should understand:
This is particularly important in family cases where the sponsor assumes the marriage will continue indefinitely.
Immigration law does not necessarily make the financial obligation disappear when the relationship does.
Divorce does not ordinarily terminate the I-864 obligation.
That fact alone makes the I-864 one of the most important documents in a family-based immigration case.
Form I-864 sits underneath much of family-based immigration.
The relationship may begin with:
I-130
↓
I-485 or Consular Processing
↓
I-864
↓
Green Card
The I-864 therefore connects the legal eligibility for immigration with a financial-support requirement.
It also creates a responsibility that can continue after the Green Card is issued.
That is why the I-864 should never be reduced to:
“The income form.”
It is more accurately understood as:
the financial sponsorship contract behind the immigrant’s application.
For petitioners, the lesson is simple:
Know what you are signing.
For intending immigrants, the lesson is equally important:
Know what your sponsor is legally undertaking.
And for both, accuracy matters.
Form I-864 is one of the most consequential forms in family-based immigration because it combines a financial eligibility requirement with a legally enforceable sponsorship obligation.
The sponsor generally needs to establish:
If the sponsor’s income is insufficient, a household member or joint sponsor may sometimes provide a solution, but those mechanisms are not interchangeable.
The financial guidelines also change.
For 2026, the standard requirement for most sponsors is 125% of the current HHS Federal Poverty Guidelines, subject to the applicable household size and geographic schedule. (aspe.hhs.gov)
Most importantly, the I-864 is not simply paperwork.
It is a commitment.
And that commitment can survive circumstances that the sponsor may not expect—including divorce.
The right time to understand the obligation is before the form is signed.

Form I-864 is the Affidavit of Support that a qualifying sponsor submits to accept financial responsibility for an intending immigrant.
Most family-based immigrants need an I-864, as do certain employment-based immigrants. Exceptions exist for specific categories and circumstances.
For most sponsors in the 48 contiguous states and D.C., the standard is 125% of the applicable 2026 Federal Poverty Guidelines. For a household of four, that is $41,250. (aspe.hhs.gov)
Generally 125%. Active-duty members of the U.S. Armed Forces sponsoring a spouse or minor child generally use the 100% threshold. (uscis.gov)
Potentially, if the spouse qualifies as a household member under the applicable rules and submits the required Form I-864A.
A joint sponsor is a separate qualifying sponsor who independently meets the applicable financial requirements and accepts the legal obligations associated with the sponsored immigrant.
No. A joint sponsor generally does not have to be related to the petitioner or intending immigrant.
Potentially. Qualifying assets may be used to supplement insufficient income, subject to the applicable rules and asset multipliers.
Potentially, if the asset satisfies the applicable requirements, including rules concerning conversion to cash and access to the funds. (travel.state.gov)
Generally, the sponsor must have U.S. domicile, although certain sponsors living abroad temporarily may still qualify.
Not automatically. The petitioner must still satisfy the basic sponsor requirements, including domicile.
Generally until the sponsored immigrant becomes a U.S. citizen, receives 40 qualifying quarters of Social Security coverage, loses lawful permanent resident status and departs, receives certain new immigration status in removal proceedings, or dies. (travel.state.gov)
No. Divorce does not ordinarily terminate the sponsor’s I-864 obligation. (uscis.gov)
No. It is an affidavit of support, not an immigration petition or application fee. Any separate filing fees associated with the underlying immigration case should be checked under the current USCIS or Department of State fee rules.
The Affidavit of Support can become complicated when income is inconsistent, household size is misunderstood, the petitioner lives outside the United States, assets are being used, or a joint sponsor is required.
