Hgg,
The process began in Jul2009.
Since then I have been requested additional documents etc etc
Nov152011 was the interview
Nov242011 Re-Medicals received at CHC London
Now awaiting either next set of documents / re-medicals / or passport request.
my advise to you, just await patiently. There is nothing you can do, but follow their requests, and hope that all goes well.
Good Luck to you
