What are the nationalities of the substantiated claimants in the USM?
A substantiated non-refoulement claim is one that has been approved, which allows the claimant to remain in the territory.
An increasingly large proportion of USM claims are substantiated on appeal.
This suggests a high rejection rate of USM claims at the initial application stage to the government.
80% of applications to work by USM claimants have been approved.
Non-refoulement claimants whose claims have been approved are not automatically granted the right to work. In order to work, one would need to apply separately to the Immigration Department. The request for approval to work is not considered through a formal system but on a “case-by-case” and “exceptional basis“.
