I-864 Affidavit of Support: Required Documents Checklist (2026)

1. What the I-864 Is and Why the Supporting Documents Matter

Form I-864, Affidavit of Support under Section 213A of the INA, is a contract an individual signs agreeing to use their financial resources to support the intending immigrant named on the affidavit. The affidavit of support is a legally enforceable contract, and the sponsor's responsibility usually lasts until the family member or other individual either becomes a U.S. citizen or is credited with 40 quarters of work (usually 10 years).

Most family-based immigrants and some employment-based immigrants use this form to show they have adequate means of financial support and are not likely to rely on the U.S. government. The form itself is straightforward — the documents are where packages go wrong. Failure to provide the tax return or evidence establishing that you were not required to file will delay action on your relative's application for permanent residence. If this information is not provided, this will result in denial of an immigrant visa or adjustment of status.

The current edition of Form I-864 is dated 10/17/24. If you complete and print this form to mail it, make sure that the form edition date and page numbers are visible at the bottom of all pages and that all pages are from the same form edition. Always download the form directly from uscis.gov to confirm you have the current version.

2. Proof of Sponsor Eligibility (Status Documents)

Every sponsor must establish their legal right to file the I-864. A financial sponsor, including a petitioner, must be at least 18 years old and either a U.S. citizen or a lawful permanent resident (LPR). The sponsor must also have a domicile (residence) in the United States.

Proof of U.S. citizen or U.S. national status includes a copy of your birth certificate, certificate of naturalization, certificate of citizenship, consular report of birth abroad to U.S. citizen parents, or a copy of the biographic data page of a valid U.S. passport. Proof of lawful permanent resident status includes a photocopy of both sides of the Permanent Resident Card or Alien Registration Receipt Card (Form I-551), or a photocopy of an unexpired temporary Form I-551 stamp in either a foreign passport or DHS Form I-94 Arrival-Departure Record.

Petitioning relatives who have already filed proof of their citizenship or immigration status with Form I-129F, Form I-130, Form I-600, or Form I-600A do not need to submit proof of their status with this affidavit. If that applies to you, you can skip the status documents — but keep a copy of the earlier filing confirmation in your records in case a question arises later.

3. Tax Records: The Backbone of Your Package

You must attach a photocopy or transcript of your federal income tax return for only the most recent tax year. If you believe additional returns may help you establish your ability to maintain sufficient income, you may submit transcripts or photocopies of your federal individual income tax returns for the three most recent years.

USCIS generally prefers an IRS tax transcript over a full tax return. Transcripts are official summaries issued by the IRS and are easy for officers to verify. They are also more convenient for sponsors because they are shorter documents with fewer pages to miss or forget. You can order a transcript free of charge at irs.gov/individuals/get-transcript.

If you submit photocopied returns instead of transcripts, include every W-2 and every 1099 that relates to those returns. Missing a single schedule is a frequent RFE trigger. If you were not required to file a tax return in any of these years, you must provide an explanation. That explanation should be in writing and cite the specific IRS rule (e.g., income below the filing threshold) to minimize the chance of an officer inquiry.

4. Current Income Evidence

Tax returns reflect the past. The I-864 is not only about past tax returns — it's about proving a reliable current income level and ability to support the household. Tax returns matter, but weak current proof commonly leads to RFEs.

You are required to provide your U.S. federal income tax return for the most recent tax year as well as proof of current employment. In practice, USCIS expects a current employer letter stating your title, salary or hourly wage, and full-time or part-time status, combined with recent pay stubs (typically the most recent 3–6 months). Self-employed sponsors should submit a current year profit-and-loss statement and recent bank statements showing consistent deposits.

If your income changed significantly after the last filed tax return — upward or downward — document it thoroughly. A new job, a promotion, or a gap in employment should all be explained with supporting paperwork. Officers compare the tax return, the current-income evidence, and the income figure written on the form. Inconsistencies between those three points are a primary RFE source.

5. Household Member Income and Form I-864A

If your income alone doesn't meet the 125% Federal Poverty Guidelines threshold, you can pool income from qualifying household members. If you are using the income of people in your household or dependents to qualify, a separate Form I-864A is required for each person whose income you will use. However, an intending immigrant whose income is being used must complete Form I-864A only if their spouse and/or children are immigrating with them.

You may count the income and assets of members of your household who are related to you by birth, marriage, or adoption. To use their income, you must have listed them as dependents on your most recent federal tax return or they must have lived with you for the last 6 months. They must also complete a Form I-864A, Contract Between Sponsor and Household Member.

Proof of each household member's residency in your household and relationship to you is required if they are not the intending immigrants or are not listed as dependents on your federal income tax return for the most recent tax year. Relationship documents can include birth certificates, marriage certificates, or lease agreements. Each I-864A-filing household member must also provide their own tax records and current income evidence, mirroring what the primary sponsor provides.

6. Assets, Joint Sponsors, and Special Situations

When income falls short of the 125% threshold, sponsors have two main paths: assets or a joint sponsor.

Using assets: Only assets that can be converted into cash within one year and without considerable hardship or financial loss to the owner may be included. The owner of the asset must include a description of the asset, proof of ownership, and the basis for the claimed value. To determine the amount of assets required to qualify, subtract your household income from the minimum income requirement (125% of the poverty level for your family size). You must prove the cash value of your assets is worth five times this difference. For a sponsored spouse or adult child of a U.S. citizen, the minimum cash value of assets must be three times the difference between the sponsor's household income and 125% of the federal poverty guideline for the household. Bank statements, brokerage statements, property deeds with a current appraisal, and mortgage payoff statements are standard asset documentation.

Using a joint sponsor: Petitioners who cannot meet this level have two choices: find a "joint sponsor" who will agree to also financially support the visa applicant, or use the income of a household member to meet the Poverty Guidelines. A joint sponsor's separate I-864 and supporting documents are required if a joint sponsor is needed. A joint sponsor's package is completely independent — they submit their own I-864 plus their own status proof, tax transcripts, and current income evidence. The petitioner still submits their own I-864 as well.

Active-duty military: If you are the petitioning sponsor and on active duty in the U.S. armed forces or U.S. Coast Guard and are sponsoring your spouse or child using 100% of the Federal Poverty Guidelines, provide proof of your active military status.

Accompanying family members: If the principal applicant is required to have a Form I-864, then any accompanying spouse or child must also be included on that affidavit of support. To meet the requirement, the accompanying spouse or child must submit a photocopy of the principal applicant's Form I-864. A photocopy of the principal's supporting documentation, however, is not required.

Foreign-language documents: If you submit any documents in a foreign language, you must include a full English translation along with a certification from the translator verifying that the translation is complete and accurate.

8. Common RFE Triggers to Avoid

The following table summarizes the most frequently documented problems with I-864 packages, drawn from USCIS's published form instructions and checklist guidance.

One detail many sponsors overlook: you must submit all pages of the Form I-864 even if they are blank. Submitting an incomplete form — even if all the relevant sections are filled in — is treated as a deficient filing.

Glossary of key terms used in this post:

• RFE (Request for Evidence): A USCIS notice asking for additional documents or clarification before a decision is made. An RFE extends processing time and does not mean the application is denied.
• Federal Poverty Guidelines (FPG): Annual HHS income thresholds used to calculate whether a sponsor qualifies. The I-864 requires 125% of FPG for most sponsors, 100% for qualifying active-duty military. The Poverty Guidelines in effect on the filing date of an Affidavit of Support are used to determine whether the income requirement is met.
• Form I-864A: A separate contract a household member signs to allow their income to be counted toward the sponsor's threshold. It does not replace the sponsor's own I-864.
• Joint Sponsor: A separate person (not the petitioner) who files an independent I-864. They must independently meet the 125% threshold for their own household size plus the sponsored immigrant.
• IRS Transcript vs. Tax Return Copy: An IRS transcript is an official IRS-issued summary of a filed return. A photocopy is a copy of the original form. USCIS prefers transcripts because they're harder to alter and easier to verify.
