Depends on the Embassy. Have you checked the Consulate Review for your Embassy here on VJ. Select your flag and you'll be taken there. Also how about the sub forums for your country or region. There are lots of tools on VJ that will help answer that question and others.
I thought I'd start the new October 2018 129f thread.
Best of luck to all new filers Currently it takes at least 6 months to receive the NOA2 for I-129F.
One of the useful tools that the US petitioner should sign up for is the USPS Informed Delivery: https://informeddelivery.usps.com/box/pages/intro/start.action.
Update your VJ timeline so that others could answer your queries more appropriately.

Once you have your WAC you can create an account in the webpage!
Good luck and welcome to your new virtual Family!
