As many times as you need to. Ideally you will have already submitted a substantially correct/complete application in the first place.
 
I got request letter to submit "PRCM - Fingerprint based criminal record check" document for myself and for my spouse. I think this is mandatory document for all applicants who are in Canada more than six months. I have submitted the same via webform. Can anyone tell me how IRCC confirms acceptance of the document. Are they going upload the document to my account ? Does anyone know what are various stages a webform goes through ?
