About this service
Form I-864 is a binding contract, not just a paperwork requirement — the sponsor is legally agreeing to financially support the family-based immigrant, at a level that keeps the household income above a set percentage of the federal poverty guidelines, for as long as the obligation remains in effect. USCIS uses it to confirm the immigrant isn't likely to become primarily dependent on public benefits after receiving a Green Card. When the primary sponsor's income alone doesn't clear the required threshold, a joint sponsor can step in and take on that same legal obligation alongside or in place of the petitioner. DocPrep helps the sponsor organize tax returns, employment records, and household size documentation, and prepares the affidavit itself, but the financial commitment being made is between the sponsor and the U.S. government — that's worth thinking through carefully, and possibly with a financial advisor or attorney, before signing.
Who this may apply to
- U.S. citizen or permanent resident petitioners sponsoring a spouse, parent, or child for a Green Card
- Joint sponsors stepping in because the primary petitioner's income doesn't meet the threshold alone
- Households with additional dependents whose income needs to be counted toward the sponsorship requirement
What DocPrep can help prepare
- Preparing Form I-864 based on the sponsor's household size and income situation
- Organizing financial evidence such as recent federal tax returns, W-2s, and employment verification letters
- Explaining the general income threshold the sponsor's household needs to meet
- Coordinating a joint sponsor's separate affidavit when the primary sponsor's income falls short
How it works
- 1
Assess household income
We review the sponsor's household size and income against the general threshold that applies.
- 2
Determine if a joint sponsor is needed
If income falls short, we identify what a joint sponsor's affidavit would need to show.
- 3
Gather financial evidence
You provide tax returns, pay stubs, and employment verification supporting the affidavit.
- 4
Prepare the affidavit
We complete Form I-864 (and a joint sponsor's I-864, if applicable) using your documentation.
- 5
Final review
You review the completed affidavit before it's submitted with the immigrant's application.
Documents you may need
Requirements vary depending on your situation. Commonly requested information may include:
- Most recent federal income tax return with all W-2s or 1099s
- Recent pay stubs or other proof of current employment income
- Employment verification letter
- Proof of U.S. citizenship or permanent resident status (passport, naturalization certificate, or Green Card)
- Household size documentation, including any dependents claimed
- Joint sponsor's separate financial documentation, if applicable
Important notes
- Signing Form I-864 creates a legally binding financial obligation that can last for years and doesn't simply end if the relationship with the immigrant changes — DocPrep prepares the paperwork but does not advise on the legal or financial consequences of taking on this obligation.
- If your income alone doesn't meet the threshold, a joint sponsor with their own separate affidavit may be needed; we can help coordinate that filing too.

Related questions
Form I-864, Affidavit of Support, is a contract in which a sponsor accepts financial responsibility for a family-based immigrant, showing the applicant will have adequate financial support. It's typically filed by the U.S. citizen or permanent resident sponsor, and sometimes a joint sponsor if the primary sponsor doesn't meet income requirements alone. We help the sponsor organize income and household documentation and prepare the affidavit — the financial obligation itself is legally binding, so if you have questions about that commitment, consider speaking with a licensed attorney or financial advisor.
No. We prepare forms and organize documents based on the information you provide, but we cannot advise you on immigration strategy, eligibility questions that require legal judgment, or how the law applies to your specific circumstances. For legal advice, please consult a licensed immigration attorney.
The specific documents depend on the service and your individual situation. Common examples include identity documents like a passport or birth certificate, prior immigration notices or receipt numbers, and civil documents such as marriage or birth certificates for family-based filings. After you submit a request, our team will confirm the exact checklist for your situation.
