Kudos to the Immigration officials for doing their duty!!! Absolutely on spot. I will request the NRI family in question to think about the whole incident in perspective and wonder if instead of them....it would have been some subversive elements......and if some bad incident would have occurred..we wud have gone blaming evryone; right from the immigration guys to the local havildar. You have made a mistake and have to face the consequences......
Enjoy your trip back to India ( with the requisite VISA's).....this is your country and your country is becoming efficient & powerful.JAI HIND
