See if you are asked for the Physical verification, then you have to visit the college campus on the given date with all the documents, in order to get all the documents verified and hence confirming your admission. As a result, yeah! you have to go for the college if you are asked to.

Now you didn't mentioned the counselling through which you are taking admission. I would recommend you to call the helpdesk in order to get confirmed.

I hope this answer helps. All the very best for your future endeavors!
