I-864 Affidavit of Support: Income, Household Size, and Sponsor Options in 2026

The I‑864 Affidavit of Support is a key part of many family-based immigration cases. A complete and accurate form prevents delays and RFEs.

Key takeaways

• Household size drives the income requirement.
• Use current, verifiable income evidence.
• Joint sponsors are allowed but must qualify independently.

Calculating household size

Include the sponsor, the immigrant, dependents on taxes, and any previous immigrants still supported by the sponsor. Miscounting is a common error.

Income evidence to include

• Most recent tax return and W‑2s.
• Recent pay stubs and employment letter.
• Proof of assets if income is short.

Joint sponsor basics

A joint sponsor must be a U.S. citizen or LPR and meet the income requirement alone. Separate I‑864 forms are required.

Common pitfalls

• Using outdated tax years.
• Missing proof for self-employment.
• Incorrect household size.

When to get legal help

Complex household situations or mixed income sources can make the form tricky. A quick review can save months of delay.
