NILE tour to India has been canceled due to visas issues. Here is the official statement by the band on their Facebook page

We are extremely sad to inform this to our fans in India that our Tour of India has been called off as the visas for 3 of the members were refused today by the Indian Embassy in Washington D.C. 2 people in the travel party were granted the visas in Houston and in Athens, but the rest were not – for reasons that none of us know . The Indian embassy has not cited any reasons for rejection of the visas. It was and is beyond the control of the band, either of the promoters or the artist management. We did all we could to make this happen and tried working on getting the 3 visas for almost a month !
The promoters – Dream Rigs Entertainment (Delhi) and Obliquity India, Lanyard Entertainment and ARK Events (Bangalore) want all fans to know who have booked tickets “online” that they shall be refunded in full by the respective ticketing companies for Delhi and Bangalore concerts. But this is not the end and all of us are going to try to get Nile back to India.
