    What is an Affidavit of Support?

    An Affidavit of Support is a legally binding document that a U.S. citizen or permanent resident (the sponsor) signs to accept financial responsibility for a foreign national who is coming to the U.S. This document is primarily used by the U.S. government to show that the immigrant won’t become a “public charge” or burden on the state for financial support.

    Let’s take a look in more detail.

    Affidavit of Support Format

    An Affidavit of Support should include:

    • The affiant’s full name, address, birthdate, and place.
    • Their relationship to you and your spouse.
    • How they met you.
    • Duration and frequency of their interactions with you.
    • Date and signature.

    While notarization isn’t mandatory, adding a statement affirming the document’s truthfulness, like “I swear under penalty of perjury that this information is accurate to my knowledge,” can add credibility.
