The National Visa Center will send an appointment letter to all interested parties notifying them of the date, time, and location of the interview. Notices are generally received approximately one month prior to the interview date. When we receive notice of the interview date, our firm will prepare the materials the applicant will need to take to the interview at the U.S. Embassy or U.S. Consulate abroad. Our firm will also provide guidance to the applicant(s) on scheduling and completing the required medical exam abroad by an authorized physician prior to the scheduled interview appointment.
