If you received a green card through a family-based petition, there is a document behind that process that carries serious legal weight: the Form I-864 Affidavit of Support.
For many sponsored immigrants, questions about enforcing Affidavit of Support obligations arise during or after a divorce, particularly when financial support disappears. The Affidavit of Support is not just another immigration form. It is a legally binding contract connected to the green card process.
When the financial promises in that contract are not honored, federal law provides a mechanism for enforcing them.
This article walks through how enforcing an Affidavit of Support works, why these cases frequently arise during divorce proceedings, and why federal court is often where these claims are ultimately resolved.
What Is the Affidavit of Support?
The Form I-864 Affidavit of Support is required in family-sponsored immigration cases. It is typically submitted as part of the adjustment of status or immigrant visa process when someone applies for a green card through a family member.
This requirement applies to immigration petitions filed by:
- Adult children sponsoring parents;
- U.S. citizen parents sponsoring children;
- Siblings sponsoring relatives;
- Spouses sponsoring a marriage-based green card; and
- Petitioners for fianc(é)e visas, when the applicant applies for adjustment of status.
In practice, the most common context for enforcing Affidavit of Support obligations arises in marriage-based immigration cases.
For many sponsored immigrants, the moment they begin examining their rights under the Affidavit of Support occurs during or around divorce proceedings. Sometimes the question arises in the lead-up to a divorce, sometimes during the divorce process, and sometimes after the divorce has already been finalized.
When the Affidavit of Support Becomes an Enforceable Contract
One of the most important things to understand about enforcing Affidavit of Support obligations is when the contract becomes legally binding.
When a signed Affidavit of Support is submitted to USCIS along with a green card application, it automatically becomes an enforceable contract under federal regulations.
In that contract:
- The sponsor promises the U.S. government to financially support the immigrant.
- The obligation is to ensure the immigrant’s income remains at 125% of the federal poverty guideline.
- The immigrant is considered the beneficiary of the contract, even though they do not sign the affidavit themselves.
Under 2026 gudielines, the required income level is $1,662 per month for a household of one, though the figure is adjusted periodically for inflation.
If the sponsored immigrant’s income falls below that level, the sponsor may be legally responsible for providing financial support.
A Common Scenario: Divorce and Financial Hardship
To understand how enforcing Affidavit of Support claims often arises, consider a hypothetical scenario involving three individuals:
- Maria, the sponsored immigrant
- John, her spouse and primary sponsor
- Carol, John’s sister, who signs as a joint sponsor
Maria arrives in the United States and marries John. Because she entered the country on a visitor visa and intends to remain in the United States, the couple files immigration paperwork so she can obtain permanent residency.
As part of the adjustment of status process, several forms are submitted, including:
- Form I-130, the immigrant visa petition
- Form I-485, the green card application
- Form I-864, the Affidavit of Support
John is self-employed, and his income does not appear sufficient on paper to meet immigration financial requirements. Because of this, Carol signs an additional Affidavit of Support as a joint sponsor.
Both affidavits are submitted to USCIS with Maria’s green card application, and the enforceable contracts are created at that moment.
What Happens When the Marriage Breaks Down
Later, John’s business venture fails, and he loses his source of income. Financial strain creates tension in the marriage, and the relationship ultimately falls apart.
Maria leaves the marriage. She has her green card but no job.
Maria has professional credentials from her home country and is trained as a physician, but she does not have a U.S. medical license. Because of this, she cannot work as a physician in the United States and struggles to find employment.
With no income, she asks John for financial support.
John responds that he has no money because his business collapsed. However, Maria remembers that John signed an Affidavit of Support promising to provide financial assistance if needed.
This raises the question: how can Maria enforce that contract?
Why Divorce Court Often Doesn’t Resolve Affidavit Claims
Many sponsored immigrants first attempt to enforce the Affidavit of Support obligations during divorce proceedings.
This seems like a logical place to raise the issue. Both parties are already in court, and the affidavit appears to be a contract promising financial support.
However, divorce courts frequently struggle with these claims.
A family court judge may recognize that the affidavit appears to promise financial support, but also conclude that the issue is governed by federal immigration law rather than state family law.
In those situations, a judge may decline to enforce the affidavit and suggest that the issue should be addressed in federal court instead.
Meanwhile, the divorce process continues.
In the hypothetical scenario, Maria signed a prenuptial agreement before marriage, agreeing not to seek alimony. In addition, John is unemployed and has limited financial resources. Because of these factors, the court awards little or no alimony.
Maria leaves the divorce with effectively no financial support.
This situation occurs frequently in real-world cases. Someone in Maria’s position may receive no alimony under state law even though an enforceable Affidavit of Support exists.
Bringing an Affidavit of Support Claim in Federal Court
When the issue is not resolved in divorce court, enforcing Affidavit of Support obligations often moves to federal court.
Federal law allows a sponsored immigrant to bring a lawsuit against the sponsor to enforce the contract. The legal authority for these cases comes from 8 U.S.C. §1183a(e)(1).
One major advantage of federal litigation is the attorney fee provision contained in the Affidavit of Support.
If the immigrant must hire an attorney to enforce the contract, those attorney’s fees may be paid by the sponsor. This provision often makes it possible for immigrants with little or no financial resources to obtain legal representation.
Common Defenses Sponsors Raise
Sponsors frequently attempt to dismiss these lawsuits using a legal doctrine known as res judicata.
Res judicata generally means that once a court resolves a claim, the same claim cannot be litigated again.
Sponsors often argue that because the divorce court already addressed financial issues such as alimony, the immigrant cannot bring another lawsuit seeking support.
However, federal courts across the United States have usually rejected this argument.
Alimony and Affidavit of Support enforcement are legally distinct claims. Alimony arises under state family law, while enforcement of the affidavit arises under federal immigration law.
Because these are separate legal issues, the federal case is typically allowed to proceed.
What Federal Courts Actually Examine
Another important feature of enforcing Affidavit of Support claims is how narrow the legal inquiry usually is.
In federal court, the core questions typically include:
- Was a valid Affidavit of Support signed?
- Did the immigrant obtain lawful permanent residence?
- Has the immigrant’s income been below 125% of the federal poverty guideline since obtaining residency?
Personal disputes between the parties generally do not matter.
Issues such as whether the sponsor believes the immigrant behaved badly or whether the relationship ended on good terms are typically irrelevant to the legal claim.
The case centers primarily on income and the sponsor’s contractual obligation to maintain financial support.
The Role of Joint Sponsors
In some immigration cases, a joint sponsor signs an additional Affidavit of Support.
A joint sponsor becomes involved when the primary sponsor does not meet the financial requirements for sponsoring the immigrant.
Importantly, a joint sponsor’s obligations are the same as the primary sponsor’s obligations.
In federal court, both the primary sponsor and the joint sponsor can be named as defendants. The obligation is considered joint and several, meaning the immigrant can seek support from either sponsor.
This can be especially important when the primary sponsor does not have sufficient financial resources.
How Most Affidavit of Support Cases Are Resolved
Although these lawsuits sometimes proceed to trial, the majority of federal civil cases—including Affidavit of Support claims—are resolved through mediation or settlement.
In many cases, the parties agree to a resolution that includes:
- A lump-sum payment resolving all claims under the Affidavit of Support, or
- A lump-sum payment combined with continuing monthly support
Both outcomes are possible depending on the circumstances of the case and the parties’ willingness to negotiate.
Key Takeaways About Enforcing Affidavit of Support Obligations
Several important lessons emerge when looking at how these cases unfold.
First, affidavits of support are enforceable contracts under federal law. Courts across the United States consistently recognize this.
Second, divorce proceedings do not always resolve affidavit claims effectively because the issue arises under federal immigration law rather than state family law.
Finally, federal court provides several practical advantages for enforcing Affidavit of Support obligations, including:
- Access to attorneys through the contract’s fee provision
- The ability to pursue claims against both sponsors and joint sponsors
- A legal framework specifically designed to enforce the contract
