What Is the Affidavit of Support, and Why Is It Required?

If you have any experience with family-based immigration, you’ve likely heard the term “Affidavit of Support” as you learned about the different legal procedures involved in bringing a loved one to the United States. But what does that even mean? The family immigration process involves many steps, and proving that your relative will have adequate financial backing through this particular form is one of the most important.

At the Law Office of Marron Gebremeskel PLLC, we understand how stressful immigration-related paperwork can feel. Our firm provides the clear, supportive guidance you need to help you understand every requirement and reunite with your family.

Here is a summary of what you need to know about the Affidavit of Support:

  • It is a legally binding contract to financially sponsor an intending immigrant.
  • It proves that the immigrant will not need to rely on government financial assistance.
  • Sponsors must meet specific age, residency, and income thresholds.
  • Financial obligations usually last for about a decade or until the immigrant becomes a U.S. citizen.

Below, we explain these points in greater detail to help you prepare for your sponsorship journey.

What Is the Affidavit of Support in Immigration?

The Affidavit of Support, officially known as Form I-864, is a formal contract between an individual sponsor and the U.S. government. By signing this document, you agree to use your financial resources to support the intending immigrant named on the form. The person who files the initial immigrant petition is usually required to be the primary sponsor once their relative applies for a green card.

Why Is Financial Sponsorship Required?

The United States government requires financial sponsorship to confirm that new immigrants will not become a “public charge.” The government wants proof that the immigrant has adequate financial support and will not need to rely on means-tested public benefits, such as Medicaid or food stamps. A signed, accurate Form I-864 gives the government a guarantee that the intending immigrant has a sufficient financial safety net.

Eligibility and Income Requirements

Not everyone is eligible to submit an Affidavit of Support. To qualify as a sponsor, you must meet a few basic criteria.

First, you must be at least 18 years old. You must also be a U.S. citizen or a lawful permanent resident, and you must maintain a primary residence (domicile) within the United States or its territories.

You must also meet specific financial guidelines:

  • Minimum Income: Your household income must be at least 125% of the U.S. federal poverty level or higher for your specific household size.
  • Military Exception: If you are on active U.S. military duty and are sponsoring your spouse or child, your income only needs to meet 100% of the poverty level.
  • Alternative Options: If your earned income is too low, you may be able to count the cash value of certain assets, such as savings accounts or property. You might also use the income of household members or the assets of the sponsored relative to help you meet the income requirement.

What Obligations Do Sponsors Take On?

When you sign Form I-864, you accept a serious legal responsibility. You are promising to financially support the sponsored immigrant. If the immigrant you sponsored ends up receiving means-tested public benefits, the agency that provided those benefits can legally require you to repay the costs, and even sue you in court if you refuse.

This financial obligation does not end easily. It generally continues until the sponsored immigrant:

  • Becomes a U.S. citizen.
  • Is credited with 40 quarters of work in the U.S. (which typically takes 10 years).
  • Ceases to be a lawful permanent resident and permanently departs the U.S.
  • Passes away.

It is important to note that a divorce does not end your sponsorship obligation to a former spouse.

The Affidavit of Support involves major financial commitments and strict government rules. You do not have to figure out all the implications on your own. Working with a knowledgeable legal team means greater peace of mind that your paperwork is accurate, your income calculations are correct, and your family’s future is protected.
