Is it possible to set up the scanner and notification for US-only jobs, even if my agency is not registered in the US? I would like to receive at least notifications about the appearance of US-only jobs, since we have one Agency member who is in the US.

To have an opportunity to receive notifications about US-based jobs, you need to connect a US-based business manager to your agency (only after that, filter with US-only jobs becomes available).

But, currently, we cannot add such managers to non-US-based agencies, so, unfortunately, receiving notifications about US-based jobs is not possible at the moment.
