Similar situation with my wife. My wife did biomatric on the border when she extended a visa. but CIC asked my wife the finger print for the criminal record for PR(she did biomatric on the border on Jan. 2019). so I asked it RCMP, and the officer suggested us do it again. so my wife did it again.My timeline

Today I received biomatric request of My wife but she already did it biomatric when she was in india.So she need to do it again in canada
