U.S. nonimmigrant visa applicants applying from India need to provide the address for delivery for the passport if a visa is issued at the time of scheduling the visa interview. If delivery is not available to their address, they may choose to hold the passport at the VFS or the Blue Dart location. If the applicant needs to modify the address provided for delivery, s/he may do so up to two working days prior to the date of visa interview by using the modify address option available here.
