We ask for 10-year residency, 10-year employment history and 10-year travel history. We compare that against the passport. We also use a variety of open sources of information to test whether people lied or misrepresented themselves. Through the intelligence function, we have certain countries and certain time periods that make us worried about associations, so there is an in-depth review of friends, family members and associates—a bit of a spider web of who the individual works with or spends time with.
Those are some of the tests that are applied to every single case. Then, as I mentioned, the intelligence services feed in a certain roster of individuals and aliases we should be worried about, and that screen is also applied.
