This is entirely my opinion, I could be wrong:Hey guys my tracker was updated today: citizenship test request and finger prints. YAYYY. I have not received the email yet. Can I do the fingerprints without the email?
Best not to do anything without the email.
IRCC appears to be planning and allocating specific time windows for these steps.
Once you get the email, you'll also get the confirmation that tells you where RCMP needs to send your fingerprint results.
