Reacting to the controversy, Vishwanathan's wife Aruna said they were not disappointed but irritated at the developments.
"I don't think we are disappointed, it is just that it is irritating to answer these questions. Anand has always had an Indian passport and is still an Indian passport holder. So restating the obvious is a bit irritating.
"I was asked to send a copy of Anand's passport which I did. That is the only piece of information I have. I don't know what transpired between them. Every time you look at him win, you see an Indian flag right behind him that proves that he had an Indian passport and I don't understand from where this is coming and why it has been made an issue.
"Receiving a doctorate degree while being in Hyderabad would have been nice but I think that moment has passed," she said.
