.I have answered this question. Do go through this thread.@Bryanna is it advisable to wait for some time or should be withdraw the application?
Is there some reason why you want to withdraw her application? It won't work though.
This is not unusual. Maybe IRCC is doing checks on certain facts of her application.... or else maybe her application has been selected by a random process for audit purposesHave you ever seen any such case before? What was the outcome?
