As per the suggestions from Duke's attorney, I should collect not more than 8-10 reference letters including people with whom I have worked and neutral professional peers familiar with my work and achievements.
I am planing to have 2 RLs from India, 2 from Germany, 1 from Japan, and 5 from USA. Given the positive consents from DK Srivastava (VECC) and Alok Saxena (NPD), I think, at the moment, I am good from India side and don't need any more letter, unless the content of these letters are not at par the requirements. In that case, I will certainly need your help with getting RL either from Naik or your seniors.
So, how the things are going on? Time is passing pretty
