The DS-160 form is an online application used by individuals seeking a non-immigrant visa to enter the United States. This form collects essential information about the applicant, including personal details, travel plans, and background information. It is a crucial step in the visa application process and must be completed accurately. Once the DS-160 form is submitted, applicants receive a confirmation page, which they must print and bring to their visa interview at a U.S. embassy or consulate. Completing the form correctly is vital, as any errors can delay the visa processing time.
