Ya people like you congradulate officials until it happens to you.Last year when I was travelling to US from kochi,immigration officials look at my pasport and told you have a problem,you dont have ICNR Stamp(Immigration clearence not required)on the passport.Infact US govt does'nt have any such requirement (only gulf countries insist) still this fellow was behaving ackwardly.He did'nt let me go for half an hour until I said to him,i dont mind cancelling my trip but I'll make sure you'll suffer legally if not illegally.
