Kiểm tra hồ sơ online?

Anh chị cho mình hỏi khi kiểm tra hôd sơ online mình nhận được thông báo : Please follow the instructions you received from the National Visa Center (NVC) that list the six steps you must take before NVC can schedule your visa interview appointment. This includes submitting to NVC various fees, forms and documents. Once NVC has received all the required items, they will let you know if anything is missing or incomplete. You can also find these instructions online at http://nvc.state.gov/ (English)

Cho mình hỏi như vậy mình phải đợi hay mình phải làm gì tiếp. Mình cám ơn rất nhiều
