Sponsoring an Immigrant in the U.S.: I-130, I-864, and the Green Card

Sponsoring a family member to immigrate legally to the United States is one of the most widely used pathways for family reunification — and, paradoxically, one of the most widely misunderstood. Many people confuse the roles of petitioner and financial sponsor, overlook the contractual nature of the Affidavit of Support, and underestimate how long the financial obligation remains in effect. This guide explains what it means to sponsor an immigrant, who is eligible to do so, what the current costs are, the required income thresholds, and the legal consequences of failing to honor the commitment.

Sponsorship is, at its core, a contract with the federal government. The sponsor signs Form I-864, Affidavit of Support, under penalty of perjury, committing to maintain the immigrant above 125% of the federal poverty line for as long as the obligation lasts. The document is not merely declaratory — it is legally enforceable, by both the government and the immigrant themselves.

Who Qualifies as a Sponsor

In immigration terms, a sponsor is the individual or entity that commits to financially supporting the immigrant after their entry into the United States. In family-based cases, the sponsor is the U.S. citizen or lawful permanent resident who files the petition. In employment-based cases, the sponsor is the hiring company. In both scenarios, the purpose is to assure the U.S. government that the immigrant will not become a public charge — that is, dependent on means-tested public benefits.

The Affidavit of Support I-864 serves as evidence of that assurance. The sponsor must submit federal income tax returns for the past three years, proof of employment, bank statements when applicable, and documentation of assets. The review considers the full financial picture, not just current income.

Sponsorship vs. Petition

The distinction is both legal and practical. A petition is the act of filing Form I-130, in family cases, or Form I-140, in employment cases, with USCIS. The petition establishes the qualifying relationship — family ties or a job offer — that makes the immigrant eligible for the intended Green Card category.

Financial sponsorship comes at a later stage, through the I-864, and may be undertaken by the same person who filed the petition or by a third party. In family-based categories, the general rule is that the petitioner also serves as the financial sponsor, though co-sponsors may be added when the petitioner’s income falls short.

Requirements to Sponsor

To sign a valid I-864, the sponsor must cumulatively meet all of the following criteria:

• Be a U.S. citizen or lawful permanent resident. Holders of nonimmigrant visas, even long-term ones, cannot sponsor someone for a Green Card.
• Be at least 18 years old. To sponsor parents or siblings, the sponsor must be at least 21, as required by the I-130 petitioning rules.
• Be domiciled in the United States or a U.S. territory. Domicile is demonstrated through utility bills, a lease agreement, a property deed, or equivalent documents. Sponsors temporarily abroad may qualify by showing intent to return.
• Demonstrate income of at least 125% of the federal poverty guideline for the sponsor’s household size. Active-duty military personnel sponsoring a spouse or child qualify at the 100% threshold.
• Submit the correct petition form: I-130 for family cases, I-140 for employment cases.
• Pay the applicable fees for each form in the process.
• Accept the long-term obligation, which continues until the immigrant naturalizes, accumulates 40 qualifying quarters of Social Security-covered work, permanently departs the United States, or dies.

Updated Process Costs

USCIS updated its fee schedule in April 2024, and those amounts remain in effect in 2026. Costs may vary by case, but the table below summarizes the primary charges.

The total cost, counting only government fees, typically falls between $1,500 and $2,500 for a standard family case, not including attorney fees and the medical exam, which vary by jurisdiction and case complexity.

Minimum Income Requirements for 2026

The minimum income calculation is based on the HHS Poverty Guidelines published annually by the Department of Health and Human Services. The 2025 guidelines, applicable for I-864 purposes in 2026, set the 125% thresholds for the 48 contiguous states and the District of Columbia as follows:

Each additional person adds approximately $6,875 to the threshold. Separate figures apply to Alaska and Hawaii, where the federal table uses correction factors. The household count includes the sponsor, their spouse, dependents claimed on tax returns, the sponsored immigrant, and any other immigrants covered by active I-864 forms signed by the same sponsor.

When Income Falls Short

Sponsors with insufficient income have three options. The first is to present liquid assets that make up the deficit, valued at specific ratios: three times the deficit for spouses of U.S. citizens, five times for all other cases. The second is to include a household member who signs Form I-864A, adding their income to the combined total. The third is to recruit a joint sponsor, who signs a separate I-864 and assumes full responsibility equivalent to that of the primary sponsor.

How Joint Sponsorship Works

A joint sponsor is essential when the primary sponsor cannot independently meet the 125% poverty threshold. The requirements for a co-sponsor are the same as those for the primary sponsor, with two additional rules: the co-sponsor must reside at a different address from the primary sponsor and must independently satisfy the income requirement. Unlike a household member arrangement, incomes are not combined — each sponsor must independently cover the 125% threshold for their own household, including the sponsored immigrant.

Immigrants Not Required to Have an Affidavit of Support

Certain categories of immigrants are exempt from the I-864 requirement by law, including:

• Immigrants who have accumulated 40 quarters of coverage under the Social Security Act through their own work or that of their spouse.
• Self-petitioners under Form I-360, including widows and widowers of U.S. citizens.
• VAWA self-petitioners under I-360, victims of abuse by a U.S. citizen or lawful permanent resident spouse.
• Children who will automatically acquire U.S. citizenship under the Child Citizenship Act upon entering the United States.
• International adoptions by U.S. citizens under specific procedures.

The Sponsor’s Legal Obligations

Form I-864 is described by USCIS itself as a legally enforceable contract. Its implications are significant:

• If the sponsored immigrant receives means-tested public benefits, the benefit-providing agency may sue the sponsor to recover the amounts disbursed.
• The immigrant has a direct cause of action against the sponsor to compel financial support up to the 125% poverty threshold, and courts have upheld this claim even after divorce.
• Personal bankruptcy does not automatically extinguish I-864 obligations, as established by settled case law across multiple federal circuits.
• In marriage-based cases, the obligation persists after divorce until one of the legally defined terminating events occurs.

Events That End the Obligation

The sponsor’s liability ends, and only ends, when one of the following events occurs:

• The immigrant naturalizes as a U.S. citizen.
• The immigrant accumulates 40 quarters of Social Security-covered work, either their own or credited from a spouse.
• The immigrant permanently departs the United States, abandoning lawful permanent residence.
• The immigrant dies.
• The sponsor dies, though the sponsor’s estate may still be liable for obligations that had already accrued.

It is important to note that the end of a marriage, in cases based on a marital relationship, does not terminate the obligation. Sponsors who divorce often seek private agreements to govern the financial relationship, though such agreements do not bind the U.S. government or the immigrant in a direct legal action.

Penalties for Non-Compliance

Failure to comply with the obligations can result in consequences of various kinds. Failing to notify USCIS of an address change within thirty days exposes the sponsor to fines ranging from $300 to $2,000. When the sponsor knew the immigrant was receiving public benefits and failed to disclose it, the fine may reach $5,000. In extreme cases, non-compliance may constitute immigration fraud, with potential consequences for the sponsor’s own immigration status.

Sponsoring a Friend

There is no immigration category that allows an ordinary U.S. citizen to directly sponsor a friend for a Green Card. Family-based immigration is limited to specific degrees of relationship: spouse, children, parents, and siblings. What a citizen friend can do is sign on as a joint financial sponsor, supplementing the income of a legitimate family petitioner — or potentially establish a company that offers qualifying employment to the friend, opening a path to a Green Card through an employment-based category, with all the requirements specific to that route.

Practical Steps to Begin the Sponsorship Process

1. Confirm personal eligibility: U.S. citizenship or lawful permanent residence, minimum age, U.S. domicile, and sufficient income.
2. File Form I-130 for the qualifying relative, with documentation proving the family relationship.
3. Track the I-130 approval by USCIS.
4. Wait for the case to be transferred to the NVC, if the immigrant is outside the U.S., or enable adjustment of status via I-485, if the immigrant is lawfully present in the U.S.
5. Submit the I-864 with complete financial documentation.
6. Attend the consular interview or USCIS Field Office interview, depending on the applicable processing pathway.
7. After approval, fulfill all long-term obligations set forth in the Affidavit of Support.
