Really amazing timing on my application!!
28/11/2008 Submitted papers via local (Islington) NCS appointment
(held by them until the following Monday as I was going to France on a day trip that weekend)
01/12/2008 Sent from Islington to Home Office
09/12/2008 Letter acknowledging receipt
19/01/2009 Letter from Home Office congratulating me on the approval of my application! (Received today 22/01/2009)
The letter says that I'll have notification from the local council within 2 weeks of my citizenship ceremony date, and that I'll get my certificate then. I was fully expecting to wait another four months!
