What Documents Do You Need for an Affidavit of Support (Form I-864)?

If you are sponsoring a family member for a green card, one of the most important parts of the application is the Affidavit of Support (Form I-864). This form is a legally enforceable contract between the sponsor and the U.S. government showing that the intending immigrant will have adequate financial support and is unlikely to become dependent on certain public benefits.

One of the most common reasons for delays in family-based immigration cases is submitting an incomplete Affidavit of Support package. Knowing which documents to include can help your case move more smoothly.

What Documents Do You Need for an Affidavit of Support?

When preparing an Affidavit of Support (Form I-864), USCIS or the National Visa Center (NVC) will generally require documents proving the sponsor's identity, immigration status, income, and, in some cases, assets.

The exact documents needed depend on your circumstances, but the following are commonly required.

1. Completed and Signed Form I-864

The sponsor must complete the current version of Form I-864 and sign it before it is submitted. An unsigned form will generally be rejected or result in a request for additional evidence.

2. Proof of U.S. Citizenship or Lawful Permanent Resident Status

The sponsor must demonstrate that they are eligible to file an Affidavit of Support. Acceptable evidence may include:

• U.S. passport

• U.S. birth certificate

• Certificate of Naturalization

• Certificate of Citizenship

• Permanent Resident Card (Green Card)

3. Federal Income Tax Returns

Sponsors are generally required to provide evidence of their most recent federal income tax return.

Depending on the case, it may also be helpful to provide:

• IRS Tax Return Transcript

• Complete federal tax return

• W-2 forms

• 1099 forms

• Schedules filed with the tax return

Tax transcripts from the IRS are often preferred because they are official government records.

4. Proof of Current Employment

Even if your tax return shows sufficient income, current employment evidence helps demonstrate that you continue to earn enough to support the intending immigrant.

Examples include:

• Recent pay stubs

• Employment verification letter

• Offer letter (if recently hired)

Affidavit of Support Income Requirements

To qualify as a financial sponsor, your household income generally must meet at least 125% of the Federal Poverty Guidelines for your household size.

Household size may include:

• You

• Your spouse

• Your dependent children

• Anyone else claimed as a dependent on your tax return

• Certain immigrants you have previously sponsored

• The intending immigrant(s)

Military sponsors petitioning for certain immediate relatives may qualify under a different income threshold.

What If Your Income Is Too Low?

If your income does not meet the required level, you may still have options.

These can include:

• Using qualifying assets

• Including the income of certain household members (with the appropriate forms)

• Obtaining a qualified joint sponsor

Each option has specific legal requirements, and not every source of income or asset qualifies.

Documents for Assets Used on Form I-864

If assets are needed to qualify, documentation may include:

• Bank statements

• Investment account statements

• Property appraisals

• Mortgage payoff information

• Vehicle ownership documents (in limited circumstances)

The value of assets must generally be documented carefully and meet applicable legal standards.

Common Mistakes When Preparing an Affidavit of Support

Some of the most common issues include:

• Forgetting to sign Form I-864

• Using outdated forms

• Submitting incomplete tax documentation

• Miscalculating household size

• Listing income that cannot legally be counted

• Failing to provide supporting documentation

• Assuming a joint sponsor is automatically acceptable

These mistakes often lead to Requests for Evidence (RFEs), additional delays, or processing complications.
