Hello aspirant,
You can collect your original certificate by writting mail or a application form to your Hod that you want to leave college and then they check for dues if any.
After that you will receive Noc certificate from college which means college as no objection  and you are leaving by your own choice.
You can collect original certificate like Transfer certificate, migration certificate from office after producing Noc issued by your department.
Congratulations for your new journey.
Hope this helps you
