What is the task of NVC?

Question

what does the NVC do with my visa application?

Answer 1

The NVC is responsible for the collection of visa application fees and visa application documentation. When an applicant's priority date meets the most recent Qualifying Date, the NVC will contact the applicant and petitioner with instructions for submitting the appropriate processing fees. After the appropriate processing fees are paid, the NVC will again contact the applicant and petitioner to request that the necessary immigrant visa documentation be submitted to the NVC.
