I received the NOA2 on November 14th. I sent a public inquiry on December 10th. I received a response yesterday and received my NVC case number. However, part of their message mentioned, "...Due to your petition type, you will not receive a request for fee payment or document submission." I thought I would need to submit the DS160 before my file would be sent to the US Embassy. I must be mistaken. Perhaps when I receive the letter from NVC indicating my file has been sent to the US Embassy, there will be instructions to complete the DS160.
