This thread is meant for information for those who are going for interview and for those who are in the last stages for 485. As we all know after the Interview the INS officer does a security check , before putting a stamp in the passport, some get the reply after the interview that security check is not completed and decision will be know later. For other they say no visa number available. What could be really happening with in this procedure ? All our experience readres please post your suggestions what you think may be happening at the INS when they do security check for the last time, is this again a IRS/ FBI check which is already completed, which does not make sense.
