We are planning to send in a completed FBI background check with my American husband's application to avoid any additional waits. We were just looking up how to get one and it says that he needs to submit his fingerprints to get the background check. But US citizens do not need to give biometrics as per the cic website. I know that they state in the guide that the background check will be requested at a later date...does everyone get a formal request for a background check? or does the IRCC pick and choose?
