The USCIS I-864 form, also known as the Affidavit of Support, plays a crucial role in the immigration process for family-based visa applicants in the United States. This legally binding document is designed to ensure that immigrants will not become a public charge, meaning they will have adequate financial support upon their arrival. The form requires a sponsor, typically a family member, to demonstrate their ability to financially support the immigrant by meeting specific income requirements. It includes detailed information about the sponsor's financial situation, including their income, assets, and household size. Additionally, the I-864 form may require supporting documentation, such as tax returns and proof of employment, to verify the sponsor's financial claims. It is important for sponsors to understand their obligations, as they may be held accountable for the immigrant's financial needs, including healthcare and basic living expenses. Failure to properly complete or submit the I-864 can lead to delays or denials in the immigration process, making it essential for sponsors to approach this form with care and attention to detail.
