Hey there,

Hope you are doing well and keeping fine..

So heres the answer to your query though your query is not very proper enough to be understood...

Still according to what i understood,your answer...

See if you take migration from a particular seat of a college or university and you are trying to get it back after migration then you are highly mistaken dear, since once a seat it gone it would be made available to another deserving candidate .. hence you cannot get that seat back once again.

Hope i have cleared your query...

With best regards.
