There is the basic case processing part, when the officer receives the file. There is an interview, and so on and so forth. Here you must perhaps wait on other agencies. There are medical issues, but also issues of security. It cannot be boiled down to "been there, done that, got the T-shirt". You cannot tell the persons responsible for security issues to speed it up because you need the data. They themselves are complaining of a lack of resources.
Are you satisfied with the time spent on processing cases, in terms of security?
