Thanks. I noticed that the status of the background checks had been set to "complete" the day the first set of fingerprints was received more than a year ago. Now, almost a month after finishing my test, and two days before my interview, I noticed that the status of the background checks have been set back to "in progress" again. I'm pretty sure that's because the first set of fingerprints are now expired and I'm going to be asked to submit fingerprints again, but IRCC's procedures are difficult to predict.
