What the affidavit of support is
Form I-864, Affidavit of Support, is a legally enforceable contract in which the petitioner promises to financially support the immigrant so they do not become a 'public charge.' Almost every family-based green card requires it, and some employment cases do too when a relative has an ownership stake in the petitioning business.
The obligation is serious: it lasts until the immigrant becomes a US citizen, is credited with 40 quarters of work (about 10 years), leaves the US permanently, or dies. Signing an I-864 is not a formality — the government or even the immigrant can sue to enforce it.
The 125% of poverty guidelines rule
The core requirement is that the sponsor's income meets or exceeds 125% of the Federal Poverty Guidelines for their household size. Active-duty members of the US armed forces sponsoring a spouse or child only need to meet 100%. The household size includes the sponsor, their dependents, the immigrant(s) being sponsored, and anyone else already on a prior I-864.
The Department of Health and Human Services updates the poverty guidelines every year, and USCIS publishes the corresponding income thresholds on Form I-864P. Always use the current year's I-864P figures for your household size rather than an old chart.
What counts as income and assets
The figure that matters most is the sponsor's current annual income, supported by the most recent federal tax return (or transcript), recent pay stubs, and an employer letter. Income from a spouse or other household member can be added if they sign Form I-864A.
If income alone is not enough, assets can fill the gap — generally the shortfall must be covered by assets worth a multiple of it (commonly five times for most sponsors, three times when a US citizen sponsors a spouse). Acceptable assets include savings, stocks, and equity in property, valued net of debts.
Joint sponsors and common mistakes
When the petitioner cannot meet the requirement even with household income and assets, a joint sponsor — any qualifying US citizen or permanent resident willing to take on the same legal obligation — can file a second I-864. The joint sponsor must independently meet the 125% threshold for their own household plus the immigrant.
Common mistakes that cause delays include using last year's poverty figures, miscounting household size, forgetting to include the immigrant in the count, submitting incomplete tax documentation, and confusing 'total income' with 'adjusted gross income' on the tax return. Double-check the current I-864P before filing.
Related Questions
How much income do I need to sponsor an immigrant?
At least 125% of the Federal Poverty Guidelines for your household size (100% for active-duty military sponsoring a spouse or child). Use the current Form I-864P for the exact dollar amount, since it changes each year.
What if my income is too low?
You can add a household member's income (Form I-864A), count qualifying assets, or bring in a joint sponsor who independently meets the requirement. Many cases use a combination.
Who counts in my household size?
Yourself, your spouse and dependents, the immigrant(s) you are sponsoring, and anyone you have previously sponsored on an I-864 whose obligation is still active.
How long does the affidavit of support obligation last?
Until the immigrant naturalizes, is credited with 40 qualifying work quarters (about 10 years), permanently leaves the US, or dies. Divorce does not end it.
Can assets replace income on the I-864?
Yes. If income is short, assets worth a multiple of the shortfall can qualify — generally five times for most sponsors, or three times when a US citizen sponsors a spouse.
