Hey Scottishmaple,
I just checked my ecas a couple minutes ago thinking I'm going to see the same stuff, and they have added "Decision made" under sponsor and "Medical received" under both sponsor and applicant! So maybe the file has to wait until it is sent to the visa office to say "medical received" ?? If so that's also good news that maybe the file has already found its way to the visa office!
Anyone? Medical received can appear any time? or when the file gets to visa office and they match it up to my husband's file is when they will write medical received?
