Affidavit of Support (Form I-864)
An affidavit of support is a legally binding contract, usually Form I-864, in which a sponsor promises the US government to financially support an immigrant so they do not become a public charge. It is required for most family-based green cards and some employment cases.
How it works
The sponsor must show household income of at least 125% of the federal poverty guidelines (100% for active-duty military sponsoring a spouse or child). For 2026, the 125% figure for a household of two in the 48 contiguous states is $27,050, per USCIS Form I-864P. If income is too low, a joint sponsor can also sign.
The obligation usually lasts until the immigrant becomes a US citizen, earns 40 quarters of work credit (about 10 years), leaves the US permanently, or dies. Divorce does not end it.
The affidavit ties into the public charge test. Read more in our public charge guide or estimate your numbers with the I-864 income calculator.
Frequently asked questions
Who needs an affidavit of support?
Most family-based green card applicants, and employment-based applicants whose relative filed the petition or owns 5% or more of the sponsoring company.
Can a joint sponsor help?
Yes. If the petitioner's income is too low, another person who meets the income test can file a separate I-864 and share liability.
Does divorce end the I-864 obligation?
No. Divorce does not end the sponsor's financial obligation.
