FYI

I only applied in Feb 09 and was approved after 4 weeks, so I guess this
info is "hot off the press".

I blacked out all the account numbers on my bank account(s) and various
investment fund(s).
I attached a covering stating that these would be provided (if neccessary)
DIRECTLY to a named person at the UK Embassy.... and never heard
anything.

National Insurance (NI) number ..... no point deleting, as you have to include
it on the form (as darren-b pointed out)

Best wishes
