Interesting. I had a lot of family fly in from different parts of the world for a wedding a couple of weeks ago. They all landed in DEL. I had gone to pick up my uncle & his kids who flew in from DFW. I had VIP access to greet him beyond the immigration counters. I saw him come down the escalator, get into the business class line & clear through in under 5 minutes. He is an American citizen without an OCI.
