Immigration Visa for Parents

[mailgip]

Hi,

I am applying for Immigration visa for both my parents.
Petition is already approved.
Case is at NVC.

Question is where do I have to submit supporting documents (eg birth certi/marriage certi etc)?

At NVC in USA, or they can submit at Mumbai US Consulate.

I am just asking it because on NVC website, it says I have to submit original documents, then I going to need 2 original/certified documents, like birth/marriage certificate of my parents and mine too.

I live in Illinois, filed petition from here.
My parents live in Ahmedabad, so it's Mumbai Consulate area.

Thanks.

You would submit the originals at NVC.
