Our name check took long because my SO's name in Mandarin translates to many common names, many "hits". I did have two FBI agents knock on my door one Saturday, posing as Jahovas and I was cleared about two weeks after that. Remember, you will not be notified when you are cleared. You must be proactive at this point. I found out by emailing "NVCinquiry@state.gov". Do this once per week until they tell you your case has been forwarded to GZ. You never know, your file may just be sitting on someone's desk. Remember that government employees aren't like your bank; they don't get points for customer service. Let them know you are out there.
