Topic: No updates/ reply from NVC

Good day Amazon! I would like to extend my hearfelt gratitude for your monthly updates. I have been religiously waiting for every monthly Visa Bulletin released until my PD finally became current. My PD is July 25, 2007 EB-3 Phils. My concern is that I have been sending emails to nvcinquiry@state.gov regarding the status of my visa application and to add my son as a dependent. I haven't receive a reply at all, not even an autoreply. My case status no. is MNL2008698005. Pls. shed a light also as to how many months should I expect for an interview. Thanks...
