Hopefully you get yours soon!!! Though it seems pretty standard to get it in about 90 days. I dont know that the K3 was ultimately worth it, since they both got put through at the same time, but its not like it cost any money Good luck!!
sorry its taken me a bit to respond. yes we're already married. the K3 is supposed to be pretty quick. though the USCIS website gives a 5 month waiting period, followed by the NVC time frame of course. Good luck!
