Most green card sponsors need an annual income of at least 125% of the federal poverty guideline for their household size. USCIS sets this threshold every year in a chart called Form I-864P, tied to the "Affidavit of Support" — the binding contract sponsors sign under Section 213A of the Immigration and Nationality Act to financially support the immigrant they're sponsoring.

If you're on active duty in the U.S. armed forces and sponsoring your spouse or child, the requirement drops to 100% of the guideline. And if you live in Alaska or Hawaii, your threshold is higher than the other 48 states, D.C., and U.S. territories, since the cost of living there is factored into the guideline.

By signing Form I-864, you're promising USCIS that the person you're sponsoring won't become a "public charge" — meaning they won't need to rely on certain government benefits. Without a sufficient affidavit, the immigrant is considered inadmissible on public charge grounds, so the green card or immigrant visa generally won't be approved until the sponsor clears this bar, though a shortfall has more than one fix.

Signing Form I-864 creates a contract courts can enforce, not just a box to check. Your financial responsibility typically continues until the immigrant becomes a U.S. citizen, earns 40 qualifying work quarters, or leaves the U.S. permanently. If the immigrant receives certain means-tested public benefits during that time, such as food stamps, Medicaid, or SSI, the government can require you to reimburse the cost.

Your household size sets your income threshold, and it's broader than most sponsors expect. Count yourself, your spouse, and any dependent children, plus every immigrant you're currently sponsoring, including people from past affidavits that are still active. Add anyone else you claim as a dependent on your tax return, too. Miscounting household size is a common trigger for a Request for Evidence. A sponsor who forgets an earlier sponsorship commitment, for example, can end up under-reporting the income they actually need to show.

The figures below reflect the 2026 federal poverty guidelines, effective March 1, 2026, per USCIS Form I-864P. Use the "all other sponsors" column unless you're active-duty military sponsoring a spouse or child.

The guideline that applies is generally the one in effect when you file your application, not when it's finally decided. The exception: if more than a year passes and USCIS or a consular officer asks for updated evidence, the guideline in effect at that later request date takes over instead. Either way, a household that qualifies under today's numbers isn't guaranteed to qualify if the case drags on long enough to trigger a new guideline year.

If your income alone doesn't clear the threshold, two fallback options don't require any math. A "joint sponsor" — someone who meets the income requirement entirely on their own and doesn't need to live in your household — can file a separate Form I-864 and take on equal legal responsibility. A family group can have up to two joint sponsors if needed, but each one must independently meet the full threshold for the specific family members listed on their affidavit; you can't combine a joint sponsor's income with your own.

Alternatively, your spouse or another relative who's at least 18 and shares your household can contribute their income using Form I-864A, a "Contract Between Sponsor and Household Member." Their income then counts toward your combined household total.

If a joint sponsor or a household member's income won't fully close the gap either, assets are the last lever.

The multiplier depends on who you're sponsoring, not on your own status as a citizen or green card holder: federal regulations set the requirement at 3 times the shortfall if you're a U.S. citizen sponsoring a spouse or a child who's 18 or older, and 5 times the shortfall for every other relationship, including siblings, parents, minor children, and any case where the sponsor is a green card holder rather than a citizen.

Say you're a U.S. citizen sponsoring your spouse, with a household of four in the contiguous U.S., and your income is $30,000 a year. The 125% threshold for a household of four is $41,250, so you're short by $11,250. Multiply that shortfall by 3, and you'd need to show at least $33,750 in qualifying assets: savings, stocks, or the net value of property you could convert to cash within a year.

Sponsoring a sibling or parent, or sponsoring as a green card holder, means using the 5x multiplier instead. That same $11,250 shortfall would require $56,250 in assets.

A tax return alone often isn't enough. USCIS reviews your income as of the time of filing, so a return that's a year or more old may not reflect what you're currently earning. Pairing it with recent pay stubs helps avoid a request for more evidence.

If you're sponsoring a spouse for a green card, an attorney can also walk you through the marriage-based process end to end, not just the income piece.

Attorneys with Marble work on a fixed price, with no hourly billing, and can review your income, assets, and household size before you file.

Meeting the income requirement is about proving your case with the right numbers and the right paperwork, not guessing. Start with the 2026 chart above, count your household carefully, and line up documentation before you file. If the numbers don't add up on their own, a joint sponsor, household income, or assets can usually close the gap.
