Hello candidate,

There is no term actually like surrendering the seat used in college admission processes or even in counselling rounds.

Referring that you mean surrounding of seat as withdrawing from the Admission process, hence you should withdraw your application form at first for exiting from the next rounds.

You also have the option to get back your application fee, but for that you to exit from the the admission process within a certain time interval only and will not have to you submit any documents in further.

Have a good day. I hope that this answer helps you!!
