I got my fingerprints done from the State Crime Records Bureau - I got two sets so I paid a whopping Rs.1000. I had brought with me printouts of the fingerprint form on bond A4 paper, but the agency guy suggested I do it on "board" paper - a thick A4 sheet that's also slightly glossy.
I came back with this after the Xerox hassle and the stupid process of going all the way to SBI in another part of the city to make the payment, got my prints done and submitted them to FBI.
FYI, I don't live in Chennai either.
Result? Fingerprints rejected by FBI after 5 months of waiting!!
I'm now sending fresh prints myself with using nothing but "kaajal".
What is the limit to how many sets you can send? I'm planning to send 5-6. Also, how many corrections can you make and do they give a damn if it's not a "Re-Tab" ? Some BS terminology!
