An Affidavit of Support is a legal document that is used to provide evidence that an individual or organization is financially responsible for another person or entity. It is typically used in situations where an individual or organization is sponsoring someone else, such as a student, immigrant, or refugee. The affidavit is a legally binding contract between the sponsor and the sponsored individual or organization that outlines the financial obligations of each party. The most common type of Affidavit of Support is the Form I-864, which is used to sponsor an individual for permanent residency in the United States. The Form I-134 is another type of Affidavit of Support used to sponsor an individual for temporary residency in the United States. Other types of Affidavit of Support include Form I-360 for refugees and asleep, Form I-945 for those admitted into the U.S. as a refugee or Ashlee, and Form I-526 for those petitioning for an alien relative.
