In TAT there mentioned to affix a recent photo and sign across photo,can I have clarity that who have to sign , me or my college principal?
Whenever there is mentioned that sign across the photo it means that you have to sign in such a manner that your half sign should be on the paper and half on the photograph which you have pasted. It must be done in one go, don't do overwriting even if nothing is visible on the photograph. You don't have to get it signed by your principal.
