The problem is that the airport staff are not enforcing this all the time
I have an OCi which is supposed to be a different queue and that worked very well in October and I was able to clear immigration in around 10 or 15 minutes.. Was very happy after the 2 hrs plus I ended up on my previous trip when they introduced finger prints..
on my last trip last month many e visa holders were also allowed into the OCI queue and e visa takes time to process
Took me over an hour to clear immigration !!
The e visa section ( far end on left side ) was literally empty when I passed through after all this .
so the experience varies depending on the staff on the day
