The processing of your case has been delayed. A check of our records establishes that your case is not yet ready for decision, as the required security checks remain pending. Until the security checks have been completed, we cannot move forward on your case. These security checks are required to be completed on all applicants who apply for the immigration benefit you are seeking. We will make every effort to make a decision on this case as soon as the security checks are complete.
