I got the same email from Ottawa saying file is under review and requires additional verification, this tempted me to send email to Ralph but he replied eligibility and security not initiated yet, all confusingI believe with additional verification they mean review required. Are you sure there are no comments by the agent in your latest GCMS? The next time you call just ask the agent specifically that in which part is the additional verification required, is it eligibility, proof of funds, POE, Security, Criminality or something else.
