NVC is the National Visa Center, it's the step after the NOA2. Once NOA2 is done, they send to NVC, after it get the case in some days they will send to the regional consulate of your country. Once the consulate get the case, they will send the Pack 3, it's the e-mail with the information of your interview in the consulate.

NVC es el Centro Nacional de Visas, es el paso después del NOA2. Una vez que se realiza el NOA2, envían a NVC , luego de recibir el caso, en algunos días lo enviarán al consulado regional de su país. Una vez que el consulado obtenga el caso, enviarán el paquete 3, es el correo electrónico con la información de su entrevista en el consulado.

Thank you
