my friend has an undocumented status in the US for more than 10 years now. He got married to his girlfriend who is Canadian Permanent resident on August 2016. His wife filed for spousal sponsorship last November 2017. While in process he was requested an FBI clearance, which he did accomplished. Until now, the application has not been decided. Just want to know some idea as to what other things will be requested and how much more time will it take before the application will reach a decision. Or what happens next after providing the FBI clearance.
