The I-864 Affidavit of Support is a crucial document in the U.S. green card application process. It’s submitted to U.S. Citizenship and Immigration Services (USCIS) to demonstrate that an applicant will not become a public charge. This form requires a sponsor – typically a family member or relative – to prove they have sufficient financial resources to support the applicant. USCIS assesses the sponsor’s income and assets to determine if they meet specific requirements. Failure to adequately complete or meet the criteria outlined in the I-864 can lead to delays or outright denial of the green card application. Understanding the requirements of this affidavit is therefore essential for applicants seeking permanent residency in the United States.
