ThanksGCMS stands for Global Case Management System. It is is CIC’s single, integrated and worldwide system used internally to process applications for citizenship and immigration services. And hence all information regarding your EE application is updated here, so in order to view what is going on with your application and which processing stage it is in, you can (under Access to information act) order GCMS notes (for 20 CAD i think), these notes will arrive in around 30 days after ordering and will help you understand your application status in detail.
