I assume each case is different and they say it can take up to 6 months. Never the less, I had mine within 3 weeks so I would think you should have it fairly quick.
Usually my case would be updated after 5-6pm Afghanistan time but in recent days it has been updating right when the embassy opens daily around 9am. Is that a good thing? Im heading into my 7th month in AP. I dont know what is taking so long, if they were to deny my case they would have done so right away but It is still pending. Usually they take long time on the male visas but i am a female and have been waiting for so long.
