Thank you. I already got GCMS notes, and submitted LOE and more information about my work experience. Previous responses to webforms raised said eligibility under review and background check not started, however this last one did not mention eligibility and said BG verification in process.You should order your GCMS notes so you know what the review required is about. I'll also suggest you put a call through to the IRCC call center and ask specifically about the reason for the review required that way, you can address the issue ahead of time.
Background in process does not mean eligibility is passed. The background check consists of criminality and security checks. Your account may show background check in progress right from the day you submitted your application and may not be a true reflection of the situation. Usually, your security check will not begin until eligibility has been passed. However, there could be exceptions.
Again, I'll suggest you call the customer service center to get more details while you also order your GCMS notes. I wish you the very best.
I just hope it's good news, I am just tired of the whole process.
