This the email :
This email confirms that you have successfully submitted your permanent residence application.
We’ll review your application to make sure you:

uploaded all required documents correctly
paid the fees
We’ll send you a confirmation email (an acknowledgement of receipt or AOR) once an agent has confirmed your application is complete.
Please note that we’ll return your application to you if it is incomplete.
It can take some time before you receive the AOR.
Check your email regularly to see if you’ve received it. To avoid missing our emails, check your junk or spam folder.
