ok, as i said above (Which you must have skipped over, because that would be the only reason why your response focused on the "medical received" comment):
remember they were closed yesterday, so there wouldn't have been any updates done.
from what i've learned, just because our postal tracking says it's been received by the office, doesn't mean it has been opened.
also, if the request they sent you had a specific number of days to send in the medical, they may not even touch your application again until that date, which is called a "bring forward date". So let's say, the letter said they must receive it in 60 days... sometimes they will wait until that date to "receive" it and add it to the file. If it didn't have a specific date, just be patient. One thing we know for sure is they are slooooow. and it takes time for them to attach a document to a file after opening it.
as for decision made, i have no idea. from what others post on this thread, it seems people receive a real letter. i'm not sure why you are stressing so much about decision made when you know it's months and months away.
quite honestly, it seems you are stressing yourself out way more than is necessary. i understand this is a frustrating process, especially when we don't know what's going on until they tell us. continually focusing on what they haven't told you is only going to make the process seem longer. celebrate having sponsorship approval, and start ordering your GCSM notes if you want to know what CIC thinks of your application. they may provide insight, and they may not. The bottom line is, continuing to obsess over what ECAS doesn't say, and what you're not getting from CIC is only going to make you crazy, sick, and unbearable to be around. Just have faith that all will turn out as it should. it always does!
