In our ountry as well as through out world , lot of people are being denied with Visa and I myself have seen that USA is euqually checking ( in Montreal & Boston) all the passenger irrespective of their cast & nation including americans too.
Denying a visa to one person cannot be related with Constituencies because Indian Constituency is bigger than these type of small & petty matters.
Let us not drag contituency in this chapter and all the media should discourage this practice.
