Hi All,
Please note the following information. It may provide more clarity to a cluster of people on this forum.
1) If anyone did not receive an AOR (Acknowledgement of Receipt), but confirmed their "Application No." through any means: Linked Application to GCKey secure account, Biometric Instruction Letter (BIL), or IRCC agent has confirmed this information.
Do not worry, AOR is just mere a confirmation letter that IRCC has received your application and begun processing it. AOR is sent by the system automatically once an agent or case analyst start working on an application and sometimes applicant receive their AOR in the middle of processing of their application or it may also be possible that an applicant never receive an AOR.
2) Applicants can submit their documents/information via IRCC webform after receiving their "Application No." otherwise IRCC will not consider your sent documents/information.
