I have submitted my original certificate in another university and got admission. so,Should I need to submit the original certificates.

Original is mandatory for verification.
Admission don't required original but in time of certification.
You need to submit your original as well else u will get terminated on immediately.

Thanks,
Azim

You dont need to submit original documents to other colleges, xerox copies shall work out fine.

Only incase you secure yiur admission in another college then yiu hav eto withdraw admission from college you hav ebeen admitted with and take all certificates from them.

Because any college shall ask for original documents post admission.

Make sure you keep all original copies in one folder and all xerox copies in another.

Also do keep scanned cipies with you for safety and reproduction incase they are lost.
