My wife went for immigrant visa interview about 2 weeks ago.She said the vo didnt ask for or check any of her documents..she was asked about 3 questions which she answered..then Vo returned her passport and gave her a white form that says you case need further administrative processing, that she will be contacted within 2 weeks.its been 2 weeks already and didnt hear from the consulate..what kind do at this point?
