Financial sponsorship (I-864 Affidavit of Support): what it is and who needs it

Many clients come to our office thinking financial sponsorship is just "one more form." It is not. Form I-864, Affidavit of Support, is a binding contract between you and the U.S. government. This guide explains what you sign, what is required, and what the consequences are.

What the I-864 is

The I-864 is a legal commitment by which a person (the sponsor) agrees to financially support the immigrant at a minimum of 125% of the federal poverty line until the immigrant naturalizes, accumulates 40 quarters of work (approximately 10 years), abandons residence, or dies.

It is required in almost every family-based petition: spouses, children, parents, and siblings of U.S. citizens or permanent residents.

Who can be a sponsor

You must meet all of the following:

• Be a U.S. citizen or permanent resident.
• Be at least 18 years old.
• Be domiciled in the United States.
• Meet the income minimum (125% of the federal poverty line, or 100% if you are active-duty military sponsoring a spouse or child).

How income is calculated

USCIS looks at the gross income reported on your most recent tax return (the relevant 1040 line). If your current salary is higher than last year's, you can prove it with employer letters and recent pay stubs.

To see if you qualify, add up how many people depend on you financially, including the sponsored person, and compare to the annual Form I-864P tables.

If you do not meet the minimum income

You have several options:

1. Add assets

You can count assets (savings accounts, real estate, additional vehicles) instead of income. The net liquid value generally must be 5 times the gap between your income and what is required (3 times if you are sponsoring a U.S. citizen spouse).

2. Add household member income

If you live with relatives over 18 who also file taxes, they can sign Form I-864A and add their income to yours.

3. Use a joint sponsor

A third party (relative, friend) can sign a separate I-864. They do not have to be your relative or the immigrant's. They must meet every requirement on their own.

Your actual obligations

This is what many sponsors do not understand until it is too late:

• Divorce does not end the obligation. If you divorce the immigrant spouse, you remain financially responsible.
• Public benefits: if the immigrant receives certain means-tested benefits (non-emergency Medicaid, SNAP, TANF, SSI), the agency can sue you for repayment.
• The immigrant can sue you directly if you fail to maintain them at 125% of poverty.

When the responsibility ends

Your obligation ends only when one of these happens:

1. The immigrant naturalizes as a U.S. citizen.
2. They accumulate 40 quarters of work (about 10 years, including those of the spouse during marriage).
3. They lose permanent residence and leave the U.S.
4. They die.

It does not end with divorce, separation, or losing contact. Also see: what happens if you divorce during the green card process.

Common mistakes

• Signing without understanding it is contractual and enforceable.
• Assuming the immigrant will not use public benefits.
• Not updating your address with USCIS (you must notify changes within 30 days using Form I-865).
• Using incomplete or unsigned tax returns.

Typical supporting documents

• Most recent federal tax return (full 1040) or IRS transcript.
• W-2 or 1099 from the past year.
• Pay stubs from the past 6 months.
• Employer letter with start date, position, and salary.
• Proof of citizenship or residency (passport, naturalization certificate, green card).

Next steps

If you are sponsoring a relative or being asked to be a joint sponsor, review the obligation with an attorney before signing. [
