When applying to any foreign universities, it is mandatory that each and every transcript is officially signed by the office of the Controller of Examination put in official envelope sealed with the official Emblem of the university. Infact the theoretical necessary that the university should directly send the letter to the concerned University. However in case University cannot do so they can't give the seal letter to you and you can forward it to your respective University of choice. When you apply for official transcript the concern office will always follow this procedure they will give the seal in each and every page of the transcripts and thereby will also seal the envelope. Do not worry every university in India has the official application form by which you can apply for this transcript. Hope this clear your doubt.
