The US Transport Security Administration (TSA) has proposed a one-stop security arrangement with India to expedite flow of passengers to their destinations by phasing out rescreening of passengers at transit hubs
Erm... pardon the question but how is this supposed to work? It has to be in combination with pre clearance where you will do US immigration & customs in India. Otherwise you get in contact with your baggage on arrival in the US and the security has to be done all over.
Preclearance in India is a non starter. There is a reason why only AUH and DUB have preclearance facilities... big can of worms.
