IMPORTANT:
If your visa petition is currently processing at the National Visa Center, do not let more than one year pass without contacting NVC. If a period of one year passes from the last date of contact (by telephone, mail, or e-mail) with NVC, all submitted fees and documents expire. If this occurs, the fees must be paid again and documents must be resubmitted in order to continue the immigration process.
DO NOT mail original documents to the National Visa Center. You will need to bring these to your visa interview at the U.S Embassy or Consulate.
