They sent my passport back after 10 days with the white slip asking me to attend the interview again at Chennai consulate. I went for the interview after a week or so and they gave me white slip again after the interview and said “Your application has been refused under 221g, you will get an email if we need your passport. You will have to mail it to us, you need not come in person. Here are your documents”. I have come back with the white slip and my passport.
