The Bureau of Consular Affairs generally requires the individual applying for a visa to be present during the application process, as each applicant must provide their own personal information, biometrics, and signatures. Therefore, family members cannot apply for a visa on behalf of someone else. However, they can assist in gathering documentation, filling out forms, and providing support during the application process. It is important that the applicant reviews all requirements and ensures their application is accurate and complete. Additionally, applicants should be aware that visas cannot be issued without an interview in most cases, and the applicant will need to attend this interview personally. For detailed information about the application process and specific requirements, it may be helpful to refer to the relevant section on the Bureau of Consular Affairs' website.
