H1b visa stamping got yellow slip

Hi
I had interview on April 10th at 9.30… interview went well … vo gave yellow slip with no documents asked…
same day client got call to verify employment… next day client got email to confirm employment…
Any one gone through this type of situation…? We r just waiting now…
passport returned…
Any idea on how much time it will take…

This is pretty common, when you get a 221g situation. The time for processing is something that is really unknown and a black box. It can take few weeks to few months. You need to wait for the same. You can check Our 221g Tracker for Yellow slip Similar Cases
