Mehta, who had been invited by the University of Florida, applied for a J-1 visa given to exchange visitors. The 10-minute interview was, according to him, "bizarre, shameful, undignified and insulting". The US officer commented that Mehta was lying when the latter told him that his expertise was in "organic synthesis" (the jargon for his work). The scientist, who was given the Padmashri in 2001 and is the president of the Indian National Science Academy, was told he was "hiding something" when he answered that the IISC was involved in educational and academic activities. The essence of the interview was that both Mehta and IISC were probably involved in chemical warfare.
