Though I feel sorry for the kids.. I will ask the parents two questions about this incident:
1) Instead of traveling to India from U.S, if they were traveling to some other country like U.S would they be as negligent as they were in not even bothering to take Visa for the Kids.
2) Lot of people still face issues with valid documents when traveling to US from India, how many of these things get this kind of attention in the media
