U.S. visa applicants who are familiar with the dropbox application process may be aware that, prior to September 1, 2019, eligible applicants could just complete the visa application form, create / update profile on www.ustraveldocs.com/in, pay the visa application fee, generate the dropbox letter and submit applicable documents at one of the eleven CGI document drop-off locations from Monday to Friday, 10 a.m. to 4 p.m. This is no longer possible without an appointment. Effective September 1, 2019 eligible applicants must schedule an appointment with one of the CGI document drop-off locations to submit the same. It is important for eligible applicants to note this procedural change and plan accordingly. 

It is also important to know that at the discretion of the visa officer, the applicant may be required to appear for a personal interview. In such cases, the applicant must appear for the interview only at the consular post for which the visa application form DS160 was submitted. So, one must choose the desired consulate accordingly.
