The USCIS I-134 form, also known as the Affidavit of Support, plays a critical role in the U.S. immigration process, particularly for individuals seeking to enter the country on a non-immigrant visa. This form is primarily used to demonstrate that a visa applicant has sufficient financial support during their stay in the United States, ensuring they will not become a public charge. By completing the I-134, a sponsor, typically a U.S. citizen or lawful permanent resident, affirms their commitment to support the applicant financially. The form requires detailed information about the sponsor's income, assets, and household size, providing a comprehensive picture of their financial situation. Additionally, the I-134 must be signed under penalty of perjury, emphasizing the importance of honesty and accuracy in the information provided. Understanding the nuances of this form is essential for both sponsors and applicants, as it can significantly impact the outcome of the visa application process.
