For Texas, all we had to do was send them a test file for them to review a part of MU stage 1 req. This was done via uploading to their location per registry direction. The registry does not have to be fully operational.
Pls consider calling the registry.
Chances are the same organization will offer Immu and surveillance. At least that is how it is for Texas. So if Immu is not setup, the surveillance may not be setup too.
