The marriage-based green card process is filled with forms, but few cause as much anxiety as Form I-864, Affidavit of Support. It is the government’s way of ensuring that an immigrant will not become a “public charge” (dependent on government welfare).
For the sponsoring spouse, this form carries heavy legal weight. For the applicant, it is the key to proving financial stability. But the form itself is only half the battle. The real challenge lies in gathering the evidence to back it up.
If you submit the form without the correct evidence, USCIS (United States Citizenship and Immigration Services) will issue a Request for Evidence (RFE). An RFE pauses your application timeline, often adding months of delay to your case.
To help you avoid that, we have created the ultimate i-864 documents checklist for 2026. Whether you are a petitioner, a joint sponsor, or using assets to qualify, this guide breaks down exactly what you need to submit.
ℹ️ Key Takeaways
- Form I-864 is mandatory for almost all family-based green card applicants.
- IRS Tax Transcripts are preferred over photocopies of tax returns.
- Proof of current income (pay stubs/employment letters) is just as important as past tax history.
- Joint Sponsors must submit their own separate I-864 and supporting documents.
- Digital scans are now widely accepted, but clarity is key.
What is the I-864 Affidavit of Support?
Before diving into the paperwork, it is helpful to understand why this form exists. The I-864 form is a legally binding contract between the sponsor (the U.S. citizen or green card holder) and the U.S. government.
By signing this, the sponsor agrees to use their financial resources to support the intending immigrant. This responsibility lasts until the immigrant becomes a U.S. citizen, earns 40 quarters of work credit (usually about 10 years), dies, or leaves the U.S. permanently. Notably, divorce does not end this obligation.
Because the stakes are high, USCIS requires concrete proof that the sponsor actually has the money they claim to have. That is where your i-864 documents checklist comes in.

The Ultimate I-864 Documents Checklist
The documents required can vary depending on your specific situation (employed, self-employed, retired, or using a joint sponsor). However, the core requirements remain the same for most people.
Here is the breakdown of what you need to gather.
1. Mandatory Documents for the Sponsoring Petitioner
Every sponsoring spouse (the person filing the petition) must submit these items, regardless of their income level.
- Proof of U.S. Citizenship or LPR Status:
- Copy of U.S. Passport (biographical page); OR
- Copy of U.S. Birth Certificate; OR
- Copy of Naturalization Certificate; OR
- Copy of both sides of your Green Card (Permanent Resident Card).
- Most Recent Federal Tax Return:
- Best Option: An IRS Tax Return Transcript for the most recent tax year. (This is the gold standard because it comes directly from the IRS database).
- Alternative: A photocopy of your Form 1040 and all supporting schedules (W-2s, 1099s, Schedule C, etc.).
- Note: While only the most recent year is mandatory, providing the last 3 years is recommended if it strengthens your case.
2. Proof of Current Income
Your tax return shows what you made last year. USCIS also wants to know that you are still employed now.
- Pay Stubs: Copies of pay stubs from the last 6 months.
- Employment Verification Letter: A letter from your employer on company letterhead stating:
- Dates of employment.
- Job title.
- Nature of the job.
- Salary or hourly wage.
- Whether the position is temporary or permanent.
3. If You Are Self-Employed
Freelancers and business owners face more scrutiny. Your i-864 guide for self-employment includes:
- IRS Tax Transcripts: Strictly required (photocopies of returns are often insufficient without transcripts for self-employed individuals).
- Schedule C: Ensure this was included in your tax filing.
- Business License: If applicable in your state/city.
- Bank Statements: Personal and business bank statements for the last 6–12 months showing steady deposits.
4. If You Are Using Assets to Qualify
If your income does not meet the Income Requirements for Sponsoring Immigrant 2026 threshold, you can use assets (savings, stocks, property) to make up the difference.
- Bank Statements: Statements covering the last 12 months, showing the date the account was opened and the current balance.
- Stock/Bond Certificates: Proof of ownership and current value.
- Property Deeds: Proof of ownership, a recent appraisal by a licensed appraiser, and documentation of any liens or mortgages (you can only count the equity, not the total value).
Who Needs to File an I-864 Form?
It’s not just the main petitioner who might need to file. Depending on your financial strategy, you might have multiple people submitting forms.
The Petitioner (Primary Sponsor)
Always files an I-864. Even if the petitioner has $0 income, they must submit a form to accept legal responsibility.
The Joint Sponsor
If the petitioner doesn’t make enough money, a Joint Sponsor can step in.
- Form Required: A separate I-864 form.
- Documents: They must provide the full i-864 documents checklist listed above (Proof of status, taxes, pay stubs, employment letter).
A Household Member
If the petitioner lives with a relative (parent, adult child, sibling) who wants to contribute their income to the total household count.
- Form Required: Form I-864A (Contract Between Sponsor and Household Member).
- Documents: Proof of relationship to the sponsor (birth certificate, marriage cert) and proof of residence at the same address.

Income Requirements for 2026: The “Poverty Guidelines”
To sponsor an immigrant, you must prove your household income is at least 125% of the Federal Poverty Guidelines for your household size. (For active duty military sponsoring a spouse, the requirement drops to 100%).
In 2026, these numbers are adjusted for inflation. While the specific numbers change every year (usually released by HHS in January or February), the concept remains the same.
How to calculate household size:
- Yourself (the sponsor).
- The intending immigrant (your spouse).
- Any dependent children (under 21).
- Anyone claimed as a dependent on your latest tax return.
- Anyone else you have sponsored using an I-864 in the past who is not yet a citizen.
Real World Example:
Scenario: John lives in Texas. He wants to sponsor his wife, Maria. They have no children, but John claimed his younger brother as a dependent on his taxes last year.
Household Size: 3 (John + Maria + Brother).
John must look at the 2026 Poverty Guidelines for a household of 3 to see if he qualifies.
If John’s income is too low, he needs a Joint Sponsor.
How to Fill I-864: A Step-by-Step Overview
Knowing how to fill I-864 correctly is just as vital as the attachments. Here are the sections that cause the most trouble.
Part 1: Basis for Filing
Check the correct box. Usually, you are the “petitioner.” If you are a joint sponsor, ensure you select the box that says “I am the only joint sponsor” or “I am the first of two joint sponsors.”
Part 5: Sponsor’s Household Size
This is the math section. Be careful not to double-count people. For example, if you are sponsoring your spouse, do not count them again in the “persons not sponsored in this affidavit” section. The form creates a sum at the end—make sure that number matches reality.
Part 6: Sponsor’s Employment and Income
List your “Current Individual Annual Income.” This is what you earn this year based on your current job, not necessarily what your tax return says. You will use your employment letter and pay stubs to prove this number.
However, later in this section, you will input the “Total Income” from your tax returns for the last three years. These numbers must match your IRS transcripts exactly.

Common Mistakes to Avoid
Even with a perfect i-864 documents checklist, simple errors can result in rejection.
- Missing Tax Schedules: If you submit a photocopy of your 1040 return but forget the W-2s or Schedule C, USCIS will reject it. Solution: Just use the IRS Tax Transcript. It removes this risk entirely.
- Using Gross vs. Net Income: On the form, always use “Total Income” (Gross) from your tax return, usually found on line 9 of the 1040 (this line number can change by year, so check the instructions). Do not use your “Adjusted Gross Income.”
- Unsigned Forms: In 2026, USCIS accepts scanned signatures, but the form must be signed. You cannot type your name. You must print, sign with a black pen, and then scan it.
- Leaving Fields Blank: Never leave a field blank. If a question doesn’t apply to you, type “N/A” or “0”.
FAQ: I-864 Documents Checklist
Here are answers to the most common questions we receive at Greenbroad regarding the i-864 guide.
1. Can I use a tax return photocopy instead of a transcript?
Yes, you can, but it is risky. If you submit a photocopy of your Form 1040, you must include every single corresponding schedule (W-2, 1099, Schedule C, Schedule D, etc.). If you miss one page, you will get an RFE. We strongly recommend downloading your free Tax Return Transcript from the IRS website to avoid this error.
2. What if I didn’t file taxes last year?
If you were required to file but didn’t, you must file your late taxes immediately before submitting the I-864. If you were not required to file (e.g., your income was too low or you were a student), you must write a simple explanation letter stating why you were legally exempt from filing for that year.
3. Does the Joint Sponsor need to live with the Petitioner?
No. A Joint Sponsor does not need to be related to you or live with you. They simply need to be a U.S. citizen or Green Card holder, over 18, living in the United States, and willing to accept the financial liability.
4. Can I use my foreign income to qualify?
Generally, no. USCIS usually only counts income earned in the United States. However, if you are working abroad for a U.S. company or the U.S. military, or if you can prove your foreign income will continue unchanged after you move to the U.S. (rare), it might be considered. Most couples in this situation use a Joint Sponsor or assets.
5. How old can the supporting documents be?
Documents like pay stubs and employment letters should be recent—ideally less than 6 months old at the time you mail your application. Tax returns should always be for the most recent tax year available.
For official USCIS instructions, you can always visit the USCIS I-864 page.
Conclusion
The Form I-864 is the gatekeeper to your spouse’s green card. While the government takes it very seriously, thousands of couples successfully navigate this requirement every month. The secret is organization.
By following this i-864 documents checklist, you are doing more than just filling out forms—you are building a case that proves you are ready to build a life in the United States. Remember: detailed tax records, clear proof of current employment, and honesty are your best tools.
