Hi dear,
It's important for the student to come in person. However in case of any mishappening if you are unable to go then you can send any representative of yours with a authority letter mentioning the reason of your absence.
Hope this helps

Dear Manoj, yes. For Document verification, the candidate in question needs to be physically present. This is also samenfor Admission process. The verification cannot be done without the presence of the Candidate and authorities will not allow any exceptions for this rule. Nonguardians, sponsors or parenrs will be allowed for document verification in behalf of the candidate.
