My first time at CW was last year after moving from another area. At that time they wanted all pages of PP and 1 year record from bank, all ins/outs.
Was told it was because it was my first time in CW. Was also told this year would not require those,
all pages and full statement, just copy of bankbook and front pages, entry stamp pages, TM6 and copy of extension from last year.
Usual photos, blue book, wife's ID etc
Edit.
My money in bank always in excess of 400,000 all year
