Well, it's between 1-2 weeks for all results, and one to two weeks for it to be uploaded...
Numbers are not real, but it kinda gets you to the safe place.
So basically one moth after medical exam.
From my experience if your work doesn't require restrictions to be lifted - don't do that, don't put more pressure on the system.
Also from my experience - it took five weeks between 'application submitted' and 'work permit in the mailbox'.
If you want to lift restrictions just to have them lifted - it's not worth the wait.
