Just in case anyone is interested, I have just noticed on the UKBA website that the April figures for Visa Processing times (including settlement Visas) have been released over the last day or so.
These are as follows
4% - 10 days
4% - 15 days
12% - 40 days
87% - 80 days
100% - 90 days
These are working days I believe so approximately 87% of applications were processed within 3 months and 12% within 2 months. These figures appear similar to the times for March.
My Wife and I are in the process of awaiting a decision (submitted early April) so looks likely we will hear some time this month.....
