The Affidavit of Support is how the United States shifts public-charge risk onto a private sponsor for many family immigrant cases. Treat it as a contract, not a courtesy letter.
Who needs Form I-864?
Most family-based immigrant visa and adjustment applicants need a qualifying sponsor to file Form I-864. The sponsor is usually a US citizen or lawful permanent resident petitioner who meets domicile and income rules. Check the current Form I-864 instructions for exemptions and substitute forms; do not assume every relative petition uses the same package.
Sponsors show income with tax transcripts or returns, W-2 or wage evidence, and household-size counting against the Federal Poverty Guidelines table USCIS publishes for I-864P. If income is short, a joint sponsor or household member’s Form I-864A may be required. Keep filings organized in a USCIS online account when the case path is online.
How does this connect to the rest of the move?
The affidavit supports immigrant residence paths, not tourist entry: Apply for a residence permit and Change status of residence. After approval, the new resident still needs ordinary setup such as a green card process where applicable: Get a residence card.
Sponsors should keep clean tax records because returns are evidence: File federal taxes. Banking trails help prove ongoing income: Open a bank account. Arrival checklist: Paperwork after moving.
Common misconceptions
Assuming a one-page “I will support them” letter replaces I-864 fails.
Assuming sponsorship ends at the airport also fails; the contract can continue until specific legal end points listed in USCIS guidance.
Summary
Use Form I-864 with real income evidence and the correct household count, add a joint sponsor if needed, and read the obligation length before you sign. Family immigration cases stall when the affidavit math does not clear the guideline line.
