For our inland sponsoring case the security check is going on for like 5 month now. I believe that this is the only thing that is left, as we received AIP couple of month ago. We could wait more but there is a need for the principal applicant to visit the home country asap. So I have several questions: 1. Are there any standards/estimates/statistics how long the security check could last? 2. We don't know anything about PA that might be suspicious from the security point of view. Is there any way to know what is the reason for the delay? Is there a way to contact the agency that performs the security check? IRCC says that this has nothing to do with them, so we shouldn't contact them about the matter. 3. If the request was sent to the country of origin of PA than how long they will wait for the response? What happens if the country of origin never responds? Thank you for any input!
