Dear Hossein Arefi,
Sorry mate I didn't really get your question. Anyway, I assume your question is all about e-case status change and MR. E-cas doesn't say anything about MR. We normally receive MR a few weeks from the time 'we started processing.....' line appears. In my case, I've just got 2 lines 'we received your application...' and 'we started processing....' . In case of people who cleared their medicals they've the 3rd line ' medical results received..'
In short, when you've got your 2nd line give it a couple weeks for MR to arrive. If that doesn't happen, fire them a cse to make sure it's not lost in the post. I hope this helps and I hope I've not made a complete fool of myself.
