Hello there, I just have a question. My brother sent his Citizenship Application April 2018. I am just curious what is the next step after that? Do they email him?
yes, he will receive an email - AoR
AOR: Acknowledgement of Receipt (email or physical mail informing him that his application has been received)
After, the application will go "In process" when his file is sent from Sydney (where he originally sent his application) to the Citizenship and Immigration Canada (CIC) office closest to his home for processing.
During "In process" state, the CIC office will complete all the verification and background checks and he will be sitting for the citizenship test and interview.
Once he passes all of this and CIC is convinced he meets or do not meet the eligibility criteria, his application will change to "Decision Made" and he will be waiting for oath invite (if his application has been accepted).
