I differ to this from the beginning. No changes should be done to profile on which you got nomination. There is a rejection case for this from SINP who removed some work and shifted to personal history as suggested in the forum. I am against doing it.
you can take your decision. I dint remove though I had the same problem. not taking risk.
you can remove all work above 3 yrs because you are not claiming points...LOL not done ( to me if you dont show it in work and show it in PH then you are not in poistion to justify your job which is even bad )
