Good gracious. OMG. Why? I know some neta got visa denied. Were they trying to bring 5 more extra people? Why? Organizers do this for good motives but these artists. How can we respect these artist when they come in one visa and stay to work here. I think they should join college if they want to stay here. That is a good reason for staying in America. Also they will get some American education which otherwise would have become hard for them to get. 
In Nepal they can earn more respect than here. Why to stay here. Whoever stayed here they have no respect from Nepalese American. They lost their popularity.
