CIC has updated the eligibility requirements for applying BOWP under Express Entry. Seems like we cannot use the system generated AOR to apply BOWP. The AOR should be issued by CIO. So I am assuming if an application is in CIO Sydney with ecas status "Application Received" can be considered AOR. But I am not sure.
Determining if a positive eligibility decision has been made
The bridging open work permit (BOWP) requires that the foreign nationals have submitted their application for permanent residence and that CIC has provided a “positive eligibility assessment”. The positive eligibility assessment is considered to be made when the applicants receive their Acknowledgement of Receipt letter (not notice of receipt of electronic submission) and the following is confirmed in GCMS:
For FSWC applications
submitted prior to January 1, 2015, the status of the Ministerial Instructions activity has been set to “Met” or a positive Final Determination of Eligibility letter or email has been sent.
submitted on or after January 1, 2015, the Centralized Intake Office (CIO) has sent an Acknowledgment of Receipt letter that confirms the application has passed R10 completeness (this is not the Electronic receipt of APR notice but the letter [Acknowledgement of Receipt] issued in GCMS).
For PNP applications, the status of the Eligibility EC-QC/PNP activity has been set to “Passed” or the Acknowledgment of Receipt letter or email has been sent by the CIO.
For CEC applications, the status of the Eligibility CEC activity has been set to “Passed” or the Acknowledgement of Receipt letter or email has been sent by the CIO.
For FSTC applications, the Acknowledgement of Receipt letter or email has been sent by the CIO.
Express Entry
In the Express Entry application process, a notice and a letter are sent to the applicant. Only the letter (Acknowledgment of Receipt) can be used to support a BOWP.
A notice (Electronic receipt of APR) is automatically issued to the applicants on receipt of their electronic application submission. This notice indicates the following: “Your application is being checked to determine whether it meets the requirements of a complete application pursuant to section 10 and section 12.01 of the Immigration and Refugee Protection Regulations.” This notice cannot be used to support a BOWP, as it does not reflect that the applicant has received a “positive eligibility assessment” as required for a BOWP.
A letter (Acknowledgement of Receipt) is issued to the applicants once their application has passed a completeness check. This letter indicates the following: “CIC has reviewed your application and determined that it meets the requirements of a complete application as described in section 10 and section 12.01 of the Immigration and Refugee Protection Regulations.” This is the official Acknowledgement of Receipt letter and it may be used to support a BOWP if all other requirements are met.
