Dear Wello,
Louay is bang on right.
Security checks resume after the Medicals are submitted and through. Thats the reason why visa are delayed for applicants who have travel record to another countries after their age of 18 years with a stay of more than 6 months. Other wise, it doesn't take time.
As per the procedure of CIC, In Process status is updated only after Paper Verification of the entire File, it should not be confused with Background Checks been finished.
Infact, after In Process, Background checks (to check the genuity of all your docs submitted) and verifications are not done for each and every file.
CIC quotes "Visa offices will be expected to undertake both targeted and random verifications to detect and deter fraud. The number and percentage of cases subjected to verification should be high enough to
act as a meaningful disincentive to those who would attempt such practices. A40 makes material
misrepresentation a grounds for inadmissibility in its own right and prescribes a two-year ban on those
both directly and indirectly involved in such practices. Interviews, site visits and telephone checks have proven to be the most effective ways to detect and to combat fraud. The information gained at interviews where fraud is detected will help officers to identify current trends and patterns and to refine their profiles for ongoing use."
Verification is must for education if done from Distance Learning Institutes.
