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.
