1. Both Vjay and Vaishali is educated and they are living in US. Now a days lot of airport threaten happened all over the world. Forget the visa is a very big mistake.
2. Both are accepted that the problem is their side. It is genuine. Normally in our India Mumbai Immigration is very tough. So that they behave like this. Anyway both are children they have to thing about and give a chance... It is absolutely wrong..
3. In your letter you stated I feel ashamed of being an Indian... Remember our Indians only not plan properly (You planned this trip 3 or 4 months before itself but u forget to the visas)
Any way as a human tentancy Mumbai immigrations people should allow them...
