It was 19,000 people that applied, potentially effecting 80-100,000 family members, so wife and 2 kids each.
900 have been relocated with 3500 family members.
600 and their families are to be moved before the scheme closes.
As far as I can find it's 61,000 total. They are all required to complete strict security checks.
Now does this mean that bad actors are not exploiting the schemes? No. but they will hopefully get caught and their, photos, fingerprints etc are taken. If they break the law one would expect them to face the full extent of it.
