An Affidavit of Support is a legally enforceable promise that a U.S. sponsor will financially support an intending immigrant so they won't become a "public charge." In family-based immigration, it's filed on USCIS Form I-864, and it's far more than a formality — it's a contract with the U.S. government that can be enforced in court for years.

What the Affidavit of Support Does

When a U.S. citizen or lawful permanent resident sponsors a relative for a green card, the government wants assurance the immigrant will be financially supported. The I-864:

• Demonstrates the sponsor has enough income or assets to support the immigrant
• Creates a binding obligation to maintain that support
• Lets the government seek reimbursement if the immigrant later receives certain means-tested public benefits

Who Must File an I-864

The petitioning sponsor — the relative who filed the immigrant petition (Form I-130) — must file an I-864. Additional affidavits may be needed if the petitioner's income isn't enough:

• Joint sponsor — another qualifying person files their own I-864 to make up the shortfall.
• Household member — someone in the sponsor's household combines income using Form I-864A.

The Income Requirement: 125% of the Poverty Guidelines

The sponsor must show income at or above 125% of the Federal Poverty Guidelines for their household size (which includes the sponsor, dependents, the immigrant, and anyone previously sponsored).

• Active-duty military sponsoring a spouse or child only need to meet 100% of the guidelines.
• The poverty figures update annually, so always use the current Form I-864P poverty guidelines.

If income alone falls short, sponsors can use assets (generally valued so that they total a multiple of the shortfall — commonly five times, or three times for a spouse of a citizen) or add a joint sponsor.

The Three Main Forms

| Form | Use | |------|-----| | I-864 | Standard Affidavit of Support | | I-864EZ | Simplified version when the sponsor is the only one whose income is used and it comes entirely from W-2 wages | | I-864A | Contract for a household member adding their income to the sponsor's |

There's also I-864W (request for exemption) for the limited categories of immigrants who don't need an Affidavit of Support — for example, those who already have 40 qualifying quarters of work.

How Long the Obligation Lasts

This is the part sponsors most often underestimate. The support obligation continues until the sponsored immigrant:

1. Becomes a U.S. citizen, or
2. Has worked (or can be credited with) 40 qualifying quarters (about 10 years), or
3. Permanently leaves the United States, or
4. Dies.

Divorce does not end the obligation. A sponsored immigrant can sue the sponsor to enforce support, and government agencies can seek reimbursement for means-tested benefits.

Does the I-864 Need to Be Notarized?

No. The I-864 is signed under penalty of perjury and submitted to USCIS or the National Visa Center; it does not require a notary. (This differs from many state-court affidavits, which do require notarization.) Always follow the current USCIS instructions for the form.

Documents Usually Required

• The most recent federal tax return (or a transcript), often with the prior two years
• W-2s or 1099s
• Recent pay stubs or an employer letter
• Proof of U.S. citizenship or lawful permanent resident status
• Evidence of any assets being used to qualify

Common Mistakes

❌ Using last year's poverty guidelines instead of the current I-864P ❌ Miscounting household size (it includes the immigrant and prior sponsorees) ❌ Forgetting the obligation survives divorce ❌ Using I-864EZ when income isn't solely from W-2 wages ❌ Leaving out required tax documentation

Frequently Asked Questions

Q: Is the Affidavit of Support legally binding? A: Yes. The I-864 is an enforceable contract. The sponsored immigrant or a benefits-granting agency can sue the sponsor to enforce it.

Q: Does the obligation end if we divorce? A: No. Divorce does not terminate the I-864 obligation. It ends only on citizenship, 40 qualifying work quarters, permanent departure from the U.S., or death.

Q: What income do I need to sponsor? A: Generally at least 125% of the Federal Poverty Guidelines for your household size (100% for active-duty military sponsoring a spouse or child).

Q: Can I use a joint sponsor? A: Yes. If your income or assets fall short, a qualifying joint sponsor can file their own I-864 to cover the gap.

Q: Does the I-864 need to be notarized? A: No. It's signed under penalty of perjury for USCIS and does not require notarization.
