I called them. My eligibility was passed (conclusively), yes. Security started less than two weeks after CV and student form was uploaded. You can raise a webform and inquire about different parts of your application (eligibility, medical, security, etc).CV was requested mid-august (6 months after my AoR).
Did you order GCMS notes or send a webform since you got the request? Do you know if getting the CV request means the eligibility is conclusively passed by a case officer, or just by an analyst?
