[rohitjindal1184]

Hi,

I attended an interview in Calgary(Canada) on 7th Nov. VO kept my passport and said we need to further your application and gave a yellow 221g slip nothing ticked on it but retained the passport. She said I will get passport back after one week. I didn't get any update till now. Can I request my passport from the US consulate in an emergency. if yes what is the procedure
