The necessary security checks have a short shelf life, Smulian said, adding to the BCI's workload. A check must be started within 15 days of receiving an application, and it expires 35 days after the check is completed. Since no applications are completed that quickly, Smulian said, the checks are done several times for every applicant.
"The cases have been piling up and piling up and piling up. It's a vicious circle. The longer the cases sit, the more times you have to do a security check," Smulian said. "It's basically a system that is literally out of control."
Adding to the problem is that most immigrants have no real way to find out the status of their applications, or even whether they are being processed.
