Affidavit of Support (I-864): Income Rules, Joint Sponsors, and Common Mistakes

The I-864 Affidavit of Support is one of the most misunderstood parts of the family-based green card process. Most petitioners know they need to file one. Fewer understand what the income threshold actually requires, what happens when they fall short, or what signing it actually commits them to.

Getting it wrong is one of the more common reasons green card cases hit delays at the interview stage. At Prosperity Immigration Law, we help families in Houston and across Texas prepare the I-864 correctly the first time.

What the I-864 Is and Why It Is Required

The Affidavit of Support is a legally binding contract between the petitioner and the U.S. government. By signing it, the petitioner agrees to financially support the immigrant and repay any means-tested public benefits the immigrant receives if they cannot support themselves.

That obligation does not end when the green card is issued. It continues until the immigrant becomes a U.S. citizen, has worked and paid Social Security taxes for 40 qualifying quarters, abandons permanent residence, or dies. A divorce does not terminate it. This is one of the details that surprises people most, and it is worth understanding before the form is signed.

I-864 Income Requirements for Sponsors in Texas

The petitioner must demonstrate income at or above 125 percent of the federal poverty guideline for their household size. The poverty guidelines are updated annually, so the threshold that applied last year may not be the one that applies now.

Household size for I-864 purposes is calculated specifically. It includes the petitioner, anyone else currently listed as a dependent on the petitioner’s most recent federal tax return, any other immigrants the petitioner has previously sponsored under an I-864 who have not yet reached the point where that obligation ends, and the immigrant being sponsored in the current case.

This calculation catches people off guard. A petitioner who has sponsored a parent in the past and is now sponsoring a spouse needs to count both in their household size, which raises the income threshold. Getting the household size wrong is one of the most common errors on the form.

What Counts as Income for the I-864

USCIS looks at the petitioner’s current annual income and their most recent three years of federal tax returns. Current income is what the petitioner is earning now. Tax returns show the history.

Income from wages, salary, self-employment, rental properties, dividends, and certain other sources can be counted. Assets can also be used in some circumstances to supplement income that falls short of the threshold, though the asset calculation has its own rules.

What does not count: income from household members who are not joining in as joint sponsors, income the petitioner expects to earn in the future, or income from public benefits.

Using a Joint Sponsor for the I-864

When the petitioner’s income does not meet the 125 percent threshold on its own, a joint sponsor can step in. A joint sponsor is a separate individual who files their own I-864 and takes on the same legal obligation as the petitioner, independently and in full.

The joint sponsor does not combine their income with the petitioner’s to reach the threshold together. They must meet the threshold on their own, based on their own household size. This is a point that confuses many families who assume the incomes can simply be added together.

Who Can Be a Joint Sponsor

A joint sponsor must be a U.S. citizen or lawful permanent resident, at least 18 years old, domiciled in the United States, and able to meet the income threshold independently. They do not need to be related to the petitioner or the immigrant. A close friend, a sibling, or any qualifying individual can serve as a joint sponsor.

Choosing a joint sponsor carefully matters. They are signing a legally binding contract with real financial consequences. Anyone considering serving as a joint sponsor should understand what they are agreeing to before they sign.

Most Common I-864 Mistakes That Cause Delays

• Wrong Household Size – Household size is not just the people living in the home. Tax dependents and previous sponsorship obligations count too. Undercounting raises the threshold when the officer recalculates at the interview.
• Using the Wrong Tax Year – The I-864 requires the most recent federal tax return. Submitting one from two or three years ago when a more current one exists is a common error. USCIS wants the most current picture available.
• Mismatched Income Figures – The income on the I-864 needs to match the supporting documents. A number that does not line up with the W-2, 1099, or tax transcript raises questions that slow the case down.
• Missing Tax Transcripts or W-2s – The tax return alone is usually not enough. W-2s, 1099s, or an IRS tax transcript are typically required alongside it. Cases that arrive at the interview without them are sent away for additional documentation.
• Self-Employment Income Without Proper Documentation – Self-employed petitioners need a Schedule C or F along with the full return. Significant deductions can make reported net income look lower than actual earnings, which affects whether the threshold is met on paper.

What Happens if the I-864 Is Rejected or Insufficient

If the I-864 does not meet the requirements, USCIS or the consular officer will flag it. At an adjustment of status interview in Houston, this often means the case is not approved that day, and the couple is sent away to gather additional documentation or find a joint sponsor.

At a consular interview abroad, an insufficient I-864 can result in the visa not being issued until the issue is resolved. Both situations delay the case and, in some instances, require refiling documents that have since expired.

If you are unsure whether your income meets the threshold or whether a joint sponsor is needed, speaking with an experienced immigration attorney before the interview is a straightforward way to avoid that situation.

I-864 Rules for Divorces, Separations, and Changing Circumstances

One of the more practical questions that comes up after a green card is approved is what happens to the I-864 obligation if the marriage ends. The obligation does not end with the divorce. The petitioner remains financially responsible under the affidavit until one of the terminating conditions is met, regardless of the relationship between the parties.

This has real-world implications. Courts in some states have enforced the I-864 in divorce proceedings, allowing the immigrant spouse to seek reimbursement for public benefits or financial support directly from the petitioner based on the affidavit. It is an area of law that is still developing, but the obligation itself is clear.

Preparing the I-864 for a Texas Green Card Case

If your income is close to the threshold, your household size is complicated, or you are considering a joint sponsor, it is worth reviewing the I-864 before the interview rather than finding out something is off on the day.

Frequently Asked Questions About the I-864 Affidavit of Support

How much income do I need to sponsor my spouse for a green card?

The threshold is 125 percent of the federal poverty guideline for your household size. The guidelines are updated each year, and household size includes more than just the people you live with. It also includes tax dependents and anyone you have previously sponsored under an I-864.

Can my spouse’s income count toward the I-864 requirement?

In some cases, yes. If the immigrant is already in the United States and working, their income can be counted on a separate form called the I-864A, which is filed alongside the petitioner’s I-864. This does not apply in consular processing cases where the immigrant is abroad.

Does a joint sponsor have to live with us?

No. A joint sponsor only needs to be a U.S. citizen or permanent resident, at least 18, domiciled in the U.S., and able to meet the income threshold independently based on their own household size. They can live anywhere in the country.

How long does the I-864 obligation last?

Until the immigrant becomes a U.S. citizen, works 40 qualifying quarters under Social Security, permanently leaves the U.S., or dies. Divorce does not end the obligation.

What if I did not file taxes last year?

If you were not required to file, you can submit a signed statement explaining why along with evidence of your current income. If you were required to file but did not, that creates a more complicated situation and is worth discussing with an attorney before the I-864 is submitted.

Can assets be used instead of income on the I-864?

Assets can be used to supplement income that falls short of the threshold, but not as a full substitute in most cases. The asset calculation involves dividing the value of qualifying assets by a set number and adding that figure to annual income. The specific rules depend on the visa category and the relationship between the petitioner and the immigrant.
