Thank you for the detailed responses, they are very helpful. I had a couple more follow ups, you mentioned that you emailed nvcresearch and submitted a public inquiry, can you elaborate a little more on these two processes please. What is the exact nvcresearch email address as I tried to look it up online but couldn't find it. The other question was once NVC creates a case number and the case is sent to the embassy, than the beneficiary can apply for the DS-160 while the documents arrive at the embassy? Is there a specific status you need to wait for such as "in transit" before applying for the DS-160 or can you go ahead once you get the case number from the NVC?
