Once you pass the Eligibility stage you are Approved in Principle.Wow, last when I checked it was somewhere around 150-ish.
Can you recall what was your application status when applying for the BOWP?
I believe I only have the email that gives me the application number, and the Bio request that came with it, but none of the rest (Eligibility, criminality, medical, etc.) have shown "passed" in the online account yet. My understanding is that I can only apply for the BOWP once my application is "Approved in principle", but I don't really know at what status it is considered approved in principle.
Approved in principle / Approval in principle (AIP)
Your application is “approved in principle (AIP)” if:
you have received a letter from IRCC stating that you meet the permanent residence eligibility requirements, but
you still have to pass the medical, security and background checks for you and, if needed, your family members.
