I am a Nepalese Citizen and had received a Chinese Visa to travel to Beijing via Delhi for a Holiday. I was told in delhi Airport that I had to return directly to Nepal on my return and that I would not be allowed to come out of New Delhi Airport on my return (even though Nepalese do not require a VISA, and that we were planning to stop in Delhi for a few days - because my wife and children hold an Indain Visa. Can you let me know - if this is correct ? ...and if so why is this done. If it is not correct - where can i file a formal complaint on this ?

Thank you, A concerned Citizen - SP
