One of the most common questions people have about the immigration process is simple: what is an immigration sponsor actually liable for?
When someone signs an Affidavit of Support (Form I-864), they take on a legal financial obligation. That obligation creates enforceable rights under federal law and can expose the sponsor to significant financial liability.
In practice, Affidavit of Support sponsor liability generally falls into two main categories. One type of liability is mostly theoretical. The other is very real and frequently enforced.
Understanding the difference is essential for anyone considering becoming a sponsor.
The Two Types of Affidavit of Support Sponsor Liability
When discussing I-864 sponsor liability, it helps to think about the obligation in two main “buckets.”
The first involves potential lawsuits by government agencies.
The second involves lawsuits brought directly by the sponsored immigrant.
Federal law imposes both types of liability, but they play out very differently in practice.
⚠ Loose paraphrase flag: The “two buckets” structure is summarized from the transcript explanation.
Liability for Means-Tested Public Benefits
The first category of Affidavit of Support enforcement involves repayment of certain public benefits.
Sponsors can theoretically be sued for the cost of means-tested benefits provided to the immigrant. These include programs such as:
- Medicaid
- TANF (cash assistance)
- Food stamps
If a sponsored immigrant receives benefits under one of these programs while the Affidavit of Support remains enforceable, the sponsor could be sued for the cost of those benefits.
For example, if an immigrant were involved in a serious accident and Medicaid covered $200,000 in medical bills, the sponsor could theoretically be responsible for repaying those costs.
While that possibility exists in theory, this aspect of the Affidavit of Support is not routinely enforced anywhere in the United States.
Even during periods of stricter immigration policy in recent years, federal agencies considered making enforcement mandatory but ultimately did not implement that policy.
As a practical matter, lawsuits by government agencies to recover means-tested benefits are rarely pursued.
Can a Sponsor Be Sued Under an Affidavit of Support?
The second category of Affidavit of Support sponsor liability is very different.
A sponsored immigrant can sue their sponsor to maintain income at 125% of the federal poverty guideline while the Affidavit of Support remains enforceable.
This is where the financial responsibility of an immigration sponsor becomes a real and enforceable obligation.
If the immigrant’s income falls below that threshold, the sponsor may be required to make up the difference.
The 125% Federal Poverty Guideline Requirement
Under the Affidavit of Support, the sponsor’s obligation is tied to the federal poverty guideline.
Under the 2026 federal poverty guideline, the monthly amount discussed here for a household of one is approximately $1,662 per month.
If the immigrant is unemployed while the Affidavit of Support is enforceable, they may sue the sponsor to recover 125% of that amount, which works out to roughly:
- About $1,662 per month, or
- Around $19,950 per year
The sponsor’s obligation is based on the immigrant’s income.. If the immigrant earns more than that amount, the sponsor has no obligation to provide support and cannot be sued But if the immigrant’s income is below the specified level, they can sue the sponsor to recover financial assistance.
Attorney Fees Can Also Be Recovered
Another important aspect of I-864 sponsor liability is that the immigrant can recover attorney fees and legal costs associated with enforcing the Affidavit of Support.
If litigation is necessary, those costs can become significant.
Even cases resolved relatively early in federal litigation can involve around $20,000 in attorney fees, which can add substantial financial exposure for the sponsor beyond the monthly support obligation. Where a case proceeds to trial, legal fees are almost certain to be above $100,000.
The Bottom Line on Immigration Sponsor Financial Responsibility
In practical terms, Affidavit of Support enforcement creates two possible forms of liability for sponsors:
- Repayment of means-tested public benefits
- Legally possible
- Rarely pursued in practice
- Financial support for the immigrant
- Requires maintaining income at 125% of the federal poverty guideline
- Enforced through federal lawsuits
- May include attorney fees and litigation costs
The second form of liability is the one that sponsors should take most seriously, because it is actively enforced and can result in significant financial obligations.
Final Thoughts on Affidavit of Support Enforcement
Signing a Form I-864, Affidavit of Support creates a legally enforceable financial obligation.
While government lawsuits to recover public benefits are mostly theoretical, the obligation to maintain the immigrant at 125% of the federal poverty guideline is real and frequently enforced.
Understanding these two forms of Affidavit of Support sponsor liability is critical for anyone considering becoming an immigration sponsor.
