@qorax one more question:
Even if I ask for rescheduling "
after they inform a test date", can all of us ask for rescheduling? I am asking this because only I will be out of station and family will be here; But we prefer to do it together. Will IRCC approve their rescheduling since they are here (and a test date is fixed for them)?
(If they will allow that I can wait to reschedule till they inform a test date during my absence. Otherwise I will have to inform in advance , not to schedule during that time period.)
