so, the best way to contact a live [person in the center is choose option for scheduling an interview there..However, in our case, it said on the I-140, to start contacting them, if our file wouldn't be moved to NVC in 30 days.After 30 days, when we called, they told us to wait full 90 days, and only then to start contacting them, through that interview option on the phone. But in total, it took us 4 months, for NVC to create our file eventually. I don't know what to tell you. It is very frustrating, but nothing else you can do. Hopefully, it will go quicker for you.
On a side note... is your interview consulate going to be Paris? Do you know by chance the wait time for the E visasa interview there?
Thank you.
