Because, under U.S. law, visa records are confidential, only select individuals may submit a visa application on behalf of someone else. If you are illiterate or otherwise unable to independently complete the DS-160 visa application, you must obtain a third party to assist you. That individual must be identified on the “Sign and Submit” page of the application.
If you are under 16 years of age or are physically unable to complete the application, your parent or legal guardian may complete it for you, including clicking the “Sign Application” button. If you are under 16 years of age or are physically unable to complete the application and do not have a parent or legal guardian, then your application may be completed by anyone who has legal custody of you or a legitimate interest in you.
As always, please do not hesitate to contact Garfinkel Immigration Law Firm by phone at 704-442-8000 or via email with any additional questions and to receive more information.
