Just get it signed by your principal,I also got it at the time of the first attempt. Its no big deal.

so afterwords any scrutiny nahi ata hey na?

nahi yar aisa kuch nhi hota,its just like a confirmation that you are still in service at the time of giving of exams I guess.. Just chill,but do send it for sure..

bhai itna kya darna yaaaaaar jo hoga hoga yar its not kargil na itna matt ghabraa bhai 

BHavik dont think same may due to routine checking or on some compalint beacause some articles donot get the service certificate signed from their C.A.'s and they himself sign the same because they donot want to go their CA's for any reason whenever CA came to know of it he might complained the same to the Institute

So to avoid and traceout same fraud ICAI demanding service certificate again
