The process is similar to what colleagues have described. Applications are received and initial looks are done using the security indicators we've been updating. If a file needs to be referred for a further inadmissibility look, then that goes from the visa officer to the Canada Border Services Agency. They give us their advice and recommendation as to that inadmissibility, and if there is an inadmissibility found and we have that national interest component, then we go ahead and issue a public policy TRV.
