Does the letter replace Form I-864?

No. The I-864 is the legally enforceable document. The letter is supporting material and never substitutes for the form where USCIS requires it.

Does it need to be notarized?

The I-864 does not require notarization. For a support letter it depends on the context; check the specific requirements of your filing.

Can I write it in Spanish?

USCIS requires documents in English or accompanied by a certified translation. Writing it in Spanish means you will need that translation.

No. The letter is generated entirely in your browser. Nothing is sent to or stored on any server.

This letter does NOT replace Form I-864. The legally enforceable commitment lives in that form, not here.

A starting-point template. Have an immigration attorney review it before filing, especially if your finances are complicated.

First: the letter is not the I-864

This is the costliest confusion in the topic, so it comes first. A sponsor letter is a supporting document. The legally enforceable commitment to the U.S. government lives in Form I-864, not in the letter.

Submit a letter believing it replaces the form and your case does not move. The letter accompanies, contextualizes and humanizes — but the signed I-864 is what USCIS requires.

So what is it for

A well-written letter does real work: it explains the relationship between sponsor and immigrant, gives context about finances that raw numbers do not convey, and serves as a summary for the officer reviewing the file.

It is also used where the I-864 does not apply: support letters for visitor visas, school paperwork, or accompanying an I-134 in temporary cases.

What it should contain

Sponsor's full name and status (citizen or permanent resident).
Address and contact details.
The immigrant's full name and the relationship between them.
An explicit statement of the commitment to provide financial support.
Annual income and a mention of the evidence attached.
Signature and date.

Recurring mistakes

Promising more than you can sustain. The letter must be consistent with what your tax returns say. A discrepancy between your claims and your documents does more damage than writing nothing.

Signing without understanding the obligation. If you also sign the I-864, you are accepting financial responsibility for that person until they become a citizen, earn 40 qualifying work quarters, permanently leave the country, or die. Divorce does not end it.

Review before filing

This template is a starting point, not a finished document. Every case has its own circumstances, and an immigration attorney should review it before you file — especially if your finances are complicated.
