What exactly an "In process" update means these days is open to question. There was a time when it meant you were close to being finalised, especially as this update would come shortly before applicants received PPR, such as from Buffalo and London.
Nowadays...I'm not so sure, as the dates when people are getting "In process" are closer to when the file was initially received than when it was being processed months later. For example, my "In Process" says they began processing my file 5 days after the received it. To which my only response can be, "Kingston? Yeah, right. Pffffttt!"
I think eCAS updates should be taken with a truckload of salt right now until GCMS is fully in place and CIC gets around to explaining exactly what stage you are at when you get the various updates.
