Reapplying for visitor visa

[pkt]

If parents visitor visa gets rejected first time, is there a waiting time that they need to wait before they re apply? Or they can get another interview date immediately?

Can they re apply several times till they get their visa? Please let me know how this process is done.

Thanks.
