I feel very sorry for what the kids have to go through because of the mistake of their parents. Don't you think the parents took certain things in India for granted. I mean would they have travelled to USA without carring the VISAs? And if they would have what do you think would have been the treatment given to them ?
Also if the kid asks what people in India behaved like this the asnwer would be that your mom and dad made a mistake. Visas are their for a reason.
