Greetings aspirant!

Delhi university changes application status once they verify all the documents. Since you are asked to provide your original marksheet, you can mail them the documents asked ( on the mail that told you about your application status). Mostly in such cases the college's administrative staff calls you and ask you to mail the documents on a given e-mail id. But since you have not received any such information, mail it to the official e-mail id of the college. Once verified, your application status will be changed by the college officials.

Once you're approved by the Principal, step to the payment process and complete it.
